The CZ 805 BREN is a gas-operated modular assault rifle designed and manufactured by Česká zbrojovka Uherský Brod. The modular design enables users to change the calibre of the weapon to 5.56×45mm NATO or 7.62×39mm intermediate cartridges by quick change of barrel with gas tubes, breech block, magazine bay and magazine.

The CZ 805 BREN is used by various police and military forces, including in the Czech Republic, Indonesia, and Mexico.

The CZ 805 BREN was created to replace the Sa vz. 58 in the Czech Army in 2006. CZ continues to refine its design, and later released improved models; CZ BREN 2, CZ 807, CZ BREN 2 BR, CZ BREN 2 PPS and CZ BREN 3.

History

Czechoslovakia had the distinction of being the only Warsaw Pact member whose army did not issue 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 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 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, 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 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 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 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, 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.

On 13 December 2024, JSC Ukrainian Defense Industry announced that assembly of BREN 2 rifles has begun in November 2024

Project 805

For the domestic Army Replacement Rifle program development, the Lada was re-designated Project 805. The Army still did not wish to buy 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 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 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 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 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 was to be completed in 2013.

Design

The CZ 805 BREN utilises 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 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 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 CZ 805 BREN features a separate detachable magazine housing which can be replaced easily to allow 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 BREN 2 is a modular assault rifle that improves upon the original CZ 805 BREN design based from the combat experience of its users.

In October 2015, CZUB introduced an improved and lighter evolution of the CZ 805 BREN series, designated as the CZ BREN 2 (unofficially, CZ 806 BREN 2) with significantly improved ergonomics and functionality. It incorporates a number of amendments requested by the soldiers in the field, including a reduction in weight of .5 kg (1.1 lb), a re-designed cocking mechanism, 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 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 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 the CZ 805 BREN was abandoned. The cyclic rate of fire is approximately at 850 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 was introduced.

  • The CZ BREN 2 Ms was introduced in 2019. It is a semi-automatic only variant of the CZ BREN 2, intended for the civilian market and has essentially replaced the CZ 805 BREN S1.

CZ BREN 2 BR

The CZ BREN 2 BR 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.

CZ BREN 2 PPS

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 the Czech armed forces.

CZ 807

See also: CZ 807

The CZ 807 is a modular dual calibre assault rifle chambered for either the 7.62×39mm cartridge and has the ability to quickly change calibre to the 5.56×45mm NATO cartridge by replacing the magazine well module and swapping out the barrel.

CZ BREN 3

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 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, 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).
