54-599: The CZ 805 BREN was created to replace the Sa vz. 58 in the Czech Army in 2006, which later sprung a family of rifles; CZ 807 , CZ BREN 2 , CZ BREN 2 BR , CZ BREN 2 PPS and in 2024 CZ BREN 3 . The CZ 805 BREN is used by various police and military forces, including in the Czech Republic, Indonesia , and Mexico . Czechoslovakia had the distinction of being the only Warsaw Pact member whose army did not issue

108-572: A DBAL-A2 (AN/PEQ-15A) laser target designator were also ordered. In May 2010, the Army requested changes to the design before it could be operational including the change from a folding and telescoping stock to just a folding one, a pin-stabilised magazine well, a pistol grip with changeable backstraps, and the change from a 7-lug bolt to a 6-lug bolt. The first delivery of the CZ 805 occurred on 19 July 2011 with 505 guns and 20 grenade launchers. The initial order

162-408: A U.S. trademark on the term "M4." In April 2004, Colt filed a lawsuit against Bushmaster and Heckler & Koch , claiming acts of trademark infringement , trade dress infringement, trademark dilution , false designation of origin, false advertising , patent infringement , unfair competition , and deceptive trade practices. Heckler & Koch later settled out of court. On December 8, 2005,

216-629: A forward assist, a bolt release integrated into the trigger guard, dual plunger ejectors, and an anti-bump system to prevent malfunctions. Constructed from lightweight aircraft-grade 7075-T6 aluminum alloy and carbon fiber polymer , the BREN 3 weighs approximately 3 kg. It supports a modular multi-caliber system, allowing users to switch between two calibers: 5.56×45mm NATO with barrel lengths of 185 mm (7 in), 280 mm (11 in), 367 mm (14.5 in), and 420 mm (16.5 in), and .300 AAC Blackout with barrel lengths of 180 mm (7 in) and 229 mm (9 in). The CZ BREN 2 BR

270-433: A fully adjustable front post and a tangent rear sight with a sliding notch with range denominations from 100 to 800 m, graduated every 100 m. Besides this, the left side of the rear sight leaf is marked with the letter "U" ( univerzální meaning "universal"), for snap shooting, firing at moving targets and night combat at ranges up to 300 m. The rifle's sight radius is 15 inches (38 cm). The front sight base also serves as

324-408: A groove cut in the underside of the bolt and the case is flung upwards clear of the gun. The spring-loaded extractor and firing pin are both housed inside the bolt, while the fixed ejector is slotted inside the receiver. The extractor retains the firing pin and is powered by its own plunger and spring. The weapon does not have a conventional rotating hammer but a linear hammer instead. The hammer

378-415: A locked breech with rotating breech block driven by combustion gases tapped from the barrel and features a manual gas regulator. The CZ 805 BREN assault rifle is fitted with folding iron sights, but also includes an integral Picatinny rail on top of the receiver and is capable of accepting a wide variety of additional sighting equipment (red-dot or telescope day sights, night sights, lasers etc.). The weapon

432-468: A magazine well that accepted AK-74-type magazines. Converting it to accept STANAG magazines would have required the receiver to be redesigned and to have cost too much. The Army of the Czech Republic was interested in acquiring a new rifle but did not award any contracts. The Lada was then offered for export under the name CZ 2000 . In 2014, the Slovak Army began to replace its vz. 58 rifles with

486-470: A minimum 16 in (410 mm) barrel for a rifle. There is also a military M4 Type Carbine which comes with a 14.5 in (370 mm) barrel and a removable "bird cage" flash suppressor. An M4 Type Post-Ban Carbine was developed for the 1994 United States Federal Assault Weapons Ban requirements. Since the ban expired in 2004, this rifle has essentially been replaced by the M4A2 and M4A3. Some states in

540-523: A mounting platform for the vz. 58 edged bayonet . Several modernization accessories have been manufactured for the vz. 58 platform from different companies. Accessories include "tactical" bolt release, extended and/or ambidextrous magazine release paddles, ambidextrous fire mode selectors, custom handguard rails, several types of sight mounting options and various muzzle brakes and compensators. Both civilian and military users use these upgrades, and they also see frequent use with private military companies in

594-684: A new rifle for the entire military, but special forces did receive Bushmaster M4A3 carbines. With the prospect that the Army would re-arm gradually rather than on a large scale, CZUB drew up entirely new specifications in late 2005. Project 805 became the CZ XX, and then the CZ S805. Two types of guns were drawn up: ' A' models chambered for intermediate rounds including 5.56×45mm NATO , 7.62×39mm , and 6.8mm Remington SPC ; and 'B' models chambered for rifle rounds like 7.62×51mm NATO and even .300 Winchester Magnum . All had three barrel lengths to act as

648-527: A permanently fixed "Izzy" flash suppressor attached to a 14.5 in (370 mm) barrel, which brings the barrel to a total length of 16 in (410 mm). Bushmaster also produces the Patrolman's Carbine variant which features the more common removable "bird cage" flash suppressor, attached to a 16 in (410 mm) barrel, bringing the total barrel length to 17.5 in (440 mm). Both of these comply with current U.S. federal law which states

702-404: A port drilled in the barrel, 215 mm (8.5 in) from the chamber, opening into a hollow cylinder located above the barrel that contains a short-stroke piston. The vz. 58 does not have a gas regulator and the full force of the gas pressure is exerted on the piston head, propelling it backwards in a single impulsive blow. The piston is driven back only 19 mm (0.7 in) when a shoulder on

756-447: A program to create a new rifle under the name Lada S . A design was approved in 1984 that fired the smaller 5.45×39mm cartridge and could fill three roles: a subcarbine with a 185 mm (7.3 in) barrel; a rifle with a 382 mm (15.0 in) barrel; and a light support weapon with a 577 mm (22.7 in) barrel. They followed the variant family of AK-74 rifles and mostly took after their designs except for differences in

810-629: A rifle based on the Soviet AK-47 / AKM . They developed the Sa Vz. 58 in the late 1950s and although it fired the same 7.62×39mm cartridge and externally looked similar, its operating system and features were dramatically different. It was effective at the time it was introduced, but by the next decade was obsolete and hard to modify. In 1977, the Brno General Machine-Building Plants R&;D Center began

864-564: A rifle, close quarters carbine, and designated marksman rifle /LSW. A CZ S805 was presented to the Army chief of staff in November 2006, but still was not ordered. CZUB then presented the weapon publicly and spent three years showing it at exhibitions. It wasn't until November 2009 that the Czech Army finally released a tender for a new infantry rifle. The company reduced its modularity for

918-503: A simpler cleaning routine and a new lightweight folding and adjustable foot. In January 2016 the Czech Army confirmed that they had signed contracts with CZUB for 2,600 CZ BREN 2 rifles and 800 CZ 805 G1 underbarrel grenade launchers. The decision about the purchase had been taken in late October 2015 under an urgent requirement procedure because of new security threat and the migration crisis within Europe and Egypt. The CZ 805 BREN utilises

972-418: A wedge-like surface on the bolt carrier moves under the hinged breech locking piece and lifts it up and out of engagement with the locking recesses in the steel body. The hinged breech locking piece swings up and this movement provides the leverage required for primary extraction . The breech block is then carried rearwards extracting the empty cartridge casing from the chamber. A fixed ejector passes through

1026-445: Is chromium-plated to prevent fouling. The locking system features a locking piece hinged from the bolt and housed in the bolt carrier that contains two locking lugs which descend into and engage locking shoulders in the receiver 's internal guide rails. The weapon is unlocked by the short tappet-like stroke of the piston rod as it strikes the bolt carrier and drives it rearwards. After 22 mm (0.9 in) of unrestricted travel,

1080-516: Is .223 Remington/5.56×45mm NATO, and the barrel is hard chrome lined in both the bore and chamber. Unlike the current Colt M4 Carbine which features a four-position telescopic stock , the Bushmaster has a six-position stock. It is compatible with most standard AR-15 parts, can mount various attachments such as options on its picatinny rails and has the ability to accept all AR-15/ M16 type STANAG magazines . The standard M4 Type Carbine features

1134-789: Is a semi-automatic or select-fire carbine size assault rifle manufactured by Bushmaster Firearms International , modeled on the AR-15 . It is one of the Bushmaster XM15 line of rifles and carbines. The M4 Type Carbine is a copy of the Colt M4 carbine . The semi-automatic version is marketed to the U.S. civilian market in compliance with the National Firearms Act . A select fire variant can be ordered by military or law enforcement organizations with three-round burst or fully automatic capability. The rifle's caliber

1188-530: Is a different design based on a short-stroke gas piston . The only similarity it has with Kalashnikov rifles is the ammunition. Development of the weapon began in 1956; leading the project was chief engineer Jiří Čermák assigned to the Konstrukta Brno facility in the city of Brno . The Soviet Union had begun insisting that the Warsaw Pact forces standardize on a common ammunition. As a result,

1242-641: Is a gas-operated, select fire battle rifle chambered in 7.62×51 NATO calibre which is derived from the CZ BREN 2. It features a 407 mm (16 in) barrel and feeds from a 25-round magazine. The CZ BREN 2 PPS ( Czech : Puška pro Přesnou Střelbu, lit . Rifle for Precision Shooting ) is a DMR developed from CZ BREN 2 BR. The rifle is using 7.62x51 NATO cartridge, its length is 1300 mm, barrel length 457 mm (18 in), weight 4.6 kg, effective of range 600–800 m. The rifle has replaced SVD Dragunov and SVDN-3 Tiger rifles in selected units of

1296-436: Is a steel cylinder hollowed from one end almost throughout its entire length to accommodate its own operating spring. At the open end of the cylinder, a plate is welded and a groove is cut in each side of this to slide on the receiver guide rails. This linear hammer enters the hollow bolt and drives a free-floating firing pin forward with each shot. The vz.58 uses a trigger mechanism with a lever-type fire mode selector, which

1350-411: Is also a manual safety against accidental discharge. When the selector lever is placed in its rear position ("1"—single fire) the sear is disabled and the left hammer catch is rotated by the disconnector, which is depressed by the bolt carrier after every shot and is therefore disconnected from the hammer catch. The forward setting of the selector lever ("30"—automatic fire) disables the disconnector, and

1404-471: Is equipped with side-folding buttstock, which is adjustable for length of pull , and can be completely removed if maximum compactness is required. Additional equipment also includes a new, specially designed 40 mm underbarrel grenade launcher and a bayonet. The fire control unit includes a ambidextrous safety/fire selector switch, which permits semi-automatic, 2-round bursts and full automatic fire. The charging handle can also be installed on either side of

1458-432: Is similar to the vz. 58 P but includes a receiver-mounted dovetail rail bracket (installed on the left side of the receiver) used to attach an NSP2 night sight; it also has a detachable folding bipod and an enlarged conical flash suppressor . For the first two variants, the two types of stock are interchangeable and mount to the same mounting point on the rifle itself, which is identical in either variant. A successor to

1512-450: The 5.56×45mm NATO cartridge by replacing the magazine well module and swapping out the barrel. The CZ BREN 2 is a modular assault rifle that improves upon the original CZ 805 BREN design based on the experience of users. The CZ BREN 2 can be chambered in either 5.56×45mm NATO or 7.62×39mm cartridge. Switching the calibre of the rifle can be done by swapping out the barrel and mag well. CZ offers three different barrel lengths for

1566-597: The Czech armed forces . Vz. 58 The vz. 58 (or Sa vz. 58 ) is a 7.62×39mm assault rifle that was designed and manufactured in Czechoslovakia and accepted into service in the late 1950s as the 7,62 mm samopal vzor 58 , replacing the vz. 52 self-loading rifle and the 7.62×25mm Tokarev Sa 24 and Sa 26 submachine guns . While externally the vz. 58 resembles the Soviet AK-47 , it

1620-482: The Army had no funds. The country itself was splitting apart, and on 1 January 1993 it separated into the Czech Republic and Slovakia , ending 74 years of the country of Czechoslovakia. The Lada was not likely to be bought in large numbers by the smaller army. By then Česká zbrojovka Uherský Brod , which had taken over the design, had become privatised, and the company shelved the weapon for several years. In

1674-400: The CZ 805 BREN was abandoned. The cyclic rate of fire is around 850 (±100) rounds per minute. Disassembly and assembly for routine maintenance can be carried out without the need for any tools. The materials that are used to build the rifle are non-combustible as well as being resistant to impacts and mechanical damage. In 2023, a telescopic stock variant with a 207 mm (8 in) barrel

1728-440: The CZ 805 BREN. In November 2016, the Czech Army received its first batch of CZ BREN 2 modular assault rifles. In 2017, French GIGN received 68 CZ BREN 2 assault rifles chambered in 7.62×39mm and is expected to order more, in order to replace most of its Heckler & Koch HK416 . The CZ BREN 2 in 7.62×39mm was also issued to Egyptian airborne forces and Republican Guard in 2017 and 2018 respectively. On 29 September 2023,

1782-637: The Deputy Minister of Defense of the Czech Republic, Daniel Blazhkovec announced that Ukraine will receive a license to produce CZ BREN 2 rifles. These rifles will be produced under the Sich (Січ) brand, while Sellier & Bellot will set up an ammunition factory in Ukraine. For the domestic Army Replacement Rifle program development, the Lada was re-designated Project 805. The Army still did not wish to buy

1836-667: The Middle East. Additional equipment supplied with the rifle includes: 4 spare magazines, a magazine pouch (in either canvas, leather, or leatherette), vz. 58 bayonet and scabbard, cleaning brush and rod, muzzle cap, oil bottle, unified sling, front sight adjustment tool, disassembly aid and a threaded blank-firing adaptor . The vz. 58 also has a proprietary bipod, flash hider and scope mount for NSP-2 night vision scope (vz.58 P variant). Grenade launching inserts, as well as under barrel grenade launchers were developed but never adopted. Bushmaster M4A3 The Bushmaster M4 or M4A3

1890-567: The U.S. have kept these laws, so the rifle is still being produced. A trademark dispute between Bushmaster and Colt's Manufacturing Company concerned the use of the "M4" name. The M4 was developed and produced for the United States government by Colt, which had an exclusive contract to produce the M4 family of weapons until 2009. Several other manufacturers, including Bushmaster, offer M4-like firearms, nicknamed "M4geries." Colt previously held

1944-411: The charging handle back and cocking the weapon. The weapon is fed from a detachable box magazine with a 30-round cartridge capacity and made from a lightweight aluminium alloy . When the last round from the magazine is fired, the bolt will remain locked open on the bolt catch, activated by the magazine's follower. The magazine release tab is located at the base of the receiver on the left side, behind

1998-456: The competition and submitted a 5.56 mm rifle (A1) and 5.56 mm carbine (A2), as well as similarly configured 7.62 Soviet-chambered guns. This was eventually reduced to just the 5.56 mm system. When the tender was released, 27 weapons were submitted, but were reduced to just the CZ 805 and FN SCAR-L . The CZ 805 won narrowly from emphasis on a domestic design and the result was made public on 1 February 2010. FN Herstal did not contest

2052-401: The decision, and the CZ 805 was officially ordered on 18 March 2010: 6,687 CZ 805 BREN A1 assault rifles; 1,250 CZ 805 BREN A2 carbines; and 397 CZ 805 G1 proprietary grenade launchers. Each one was equipped with Meopta ZD-Dot red dot sights and iron sights. For special forces, 1,386 enhanced optical suites consisting of Meopta's DV-Mag3 daylight 3× magnifier , NV-3Mag night 3× magnifier, and

2106-517: The gas operation. In 2011, the Czech army started replacing vz. 58 with CZ-805 BREN . While vz. 58 still remains the main assault rifle of the Slovak army, the Slovak army has also been eyeing CZ-805 as a possible replacement to the aging vz. 58 rifles. The vz. 58 is a selective fire gas-operated weapon that bleeds expanding combustion gases generated in the barrel from the ignited cartridge through

2160-453: The late 1990s, the Lada project was restarted with the prospect of the Czech Republic becoming a full member of NATO . It had been converted to fire .223 Remington ammunition shortly before it was shelved, mainly because the program did not involve producing 5.45×39mm ammunition and Sellier & Bellot was already producing .223 cartridges. The restarted rifle program rechambered the rifle to NATO standard 5.56×45mm ammunition, but retained

2214-476: The left hammer catch meshes with the sear mechanism. The center ("safe") setting with the selector lever pointing vertically downwards, mechanically lowers the trigger bar and the disconnector so there is no connection between the trigger and the semi-automatic sear which holds the hammer. The rifle also has an internal safety, which prevents the weapon from discharging when out of battery. The right linear hammer catch disables it, and it can only be released by pulling

2268-600: The magazine well. The bolt carrier has a built-in guide rail used for reloading from 10-round stripper clips (from the SKS rifle). Despite their similarity, vz. 58 magazines are not interchangeable with those of the Kalashnikov-pattern weapons. An interesting feature on this rifle is the ability to quickly change the type of stock. The vz. 58 can appear either with its original fixed stock (in either beech wood or composite material) or folding steel stock, or with one of

2322-414: The many aftermarket stocks available – including AR-15 style stock adapters that mount a buffer tube to the receiver. The latter usually has the buffer tube slightly angled down as to compensate for the very low ironsights on the vz. 58. Switching between the various options requires merely removal of a bolt at the rear of the receiver and swapping in the stock of choice. The rifle's iron sights consist of

2376-422: The piston rod butts against the seating and no further movement is possible. There is a light return spring held between the piston shoulder and the seating which returns the piston to its forward position. The gas cylinder is vented after the piston has traveled back 16 mm (0.6 in) and the remaining gases are exhausted into the atmosphere on the underside of the cylinder via two ports. The entire piston rod

2430-476: The prototype, known as the "Koště" ("broom"), was designed to chamber the intermediate Soviet 7.62×39mm M43 cartridge, rather than the Czech 7.62×45mm vz. 52 round, used in both the earlier vz. 52 rifle and the vz. 52 light machine gun . The assault rifle entered service in 1958 and over a period of 25 years (until 1984), over 920,000 weapons had been produced, fielded by the armed forces of Czechoslovakia, Cuba and several Asian and African nations. The vz. 58

2484-412: The rear. The rifle also features a 4-position telescopic foldable stock, derived from the BREN 2 BR variant, which now locks into a more durable aluminum adaptor instead of the plastic one used in the BREN 2. Additionally, a PDW-style collapsible stock is available as an option. Other notable features include a chrome-lined, hammer-forged barrel, an ambidextrous, folding, non-reciprocating charging handle,

2538-590: The receiver cover, sights, and safety selector. The weapons were built by late 1985, tested starting in 1986, and was approved for production in November 1989. Shortly after that time however, the Cold War was ending and Czechoslovakia's communist party had stepped down following the Velvet Revolution . 300,000 Lada systems were planned, but by the time it was declared fit for production in February 1990,

2592-471: The two calibres, ranging from 207 mm (8 in) for the 5.56×45mm and 227 mm (9 in) for the 7.62×39mm, 280 mm (11 in), and 357 mm (14 in). The CZ BREN 2 has a lower weight compared to the CZ 805 BREN. It features a fully ambidextrous fire selector, magazine release, bolt release and charging handle. It has a simplified trigger system with three positions for "safe", "semi-auto" and "full-auto". The "2-round burst" firing mode of

2646-400: The use of STANAG or HK G36 5.56×45mm NATO magazines. It is also capable of housing a 5.56×45mm NATO 100-round Beta C-Mag . In standard configuration, the CZ 805 BREN uses a 5.56×45mm NATO proprietary 30-round magazine made of transparent polymer made by CZUB. The CZ 807 is an assault rifle chambered for either the 7.62×39mm cartridge and has the ability to quickly change calibre to

2700-402: The vz. 58 was proposed in the 1990s; the 5.56×45mm NATO ČZ 2000 assault rifle has been suggested as a possible replacement but due to a general lack of defense funds within the Czech Republic , the program was postponed. Another recent contender is the ČZW-556 assault rifle and ČZW-762 light machine gun which both use lever-delayed blowback which has more reliable accuracy and performance over

2754-417: The weapon, depending on user preferences. The CZ 805 BREN has two barrel lengths. A 360 mm (14.2 inch) barrel length for the standard assault rifle variant, the CZ 805 BREN A1 and a 277 mm (10.9 inch) barrel for the carbine variant, the CZ 805 BREN A2. The barrel is chrome-lined for accuracy and durability. The rifle features a separate detachable magazine housing which can be replaced easily to allow

The CZ BREN 3 , introduced in 2024, is an enhanced version of the BREN 2 assault rifle, operating on a short-stroke gas-piston system with a three-position adjustable gas port. Compared to its predecessor, the BREN 3 offers several improvements, such as a detachable M-LOK handguard, replacing the fixed handguard of the BREN 2, and 7 quick-detach (QD) attachment points—2 at the front and 5 at
