Czech small arms manufacturer Česká zbrojovka has introduced an improved, lighter variant of its 805 Bren rifle, called the 806 Bren 2. reports:

By the end of 2015, the Czech national arms manufacturer Ceska Zbrojovka provide the army last game of the ordered four years ago, 17,678 rifles CZ 805 Bren subkarabinków A1 and A2 CZ 805 Bren. They are announced additional purchases of construction to 2020 completely replaced in line and reserve previously used 7.62-mm rifles vz. 58.

Already in 2011, the first CZ 805 went with Czech soldiers to Afghanistan, where the weapon was tested in combat conditions. That testing also revealed problems in childhood, modified in real time by specialists sent from the country. Complained about the high price of weapons (How much is the CZ 805 BREN?, 2014-08-16), a very large mass, poor ergonomics, as well as the bad balance of the gun during firing. CZ 805 first series production also had a very long, steady flask with uncomfortable cheek pad. Soldiers also drew attention to the negative shaped handle and tensioning levers switch. Worse yet, in contrast to almost all modern construction, the cocking lever would not stop in a rear position after using all of the cartridges in the magazine. User can also easily distribute gas system for cleaning weapons.

In the course of production changed, among others, flask, introduced enlarged wings switch the type of fire. In the second production batch it was decided to replace the drain chamber. Hence, the first 7737 Brenów supplied with transparent plastic magazines construction CZ (can be used interchangeably with the German magazine H & K G36), wypinanych lever similar to the AK. Other 9700 rifles CZ 805 (200 first series and all the other) are served with typical cartridge magazines of M16 (Soon contract for weapons for ACR, 2013-12-07). The release levers are located on both sides of the chamber drain.

The refinement of weapons involved was Colonel Josef Kopecký, the Czech commander of the 7th Mechanized Brigade, which is why he and his soldiers were the first to get acquainted with a new, refined variant of Ceska Zbrojovka carbine. October 6 at the shooting range in Bzenec presented rifles CZ 806 Bren 2 A1 and subkarabinki CZ 806 Bren 2 A2 as chief of the General Staff of ACR gen. Josef Becvarovi.

Bren 2 rifles family were announced at the DSEI arms fair in London (DSEI 2015: CZ Bren announced carbine 2, 2015-09-18). This structure formed on the basis of export varieties of CZ 807, which competed in the Indian weapon trials, canceled the program MCAR. Weapon referred to as the CZ 806 is adapted for ammunition 5.56 mm x 7.62 mm and 45 x 39, while maintaining the same drain chamber. The exchange will only be subject barrel, the castle and the magazine. In a variation of 5.56 mm would be a standard magazine M16, when the gun is supplied with the cartridge Russian model will be used for identical dimensions of the upper part of the hull.

The CZ 806 Bren 2 introduced a number of amendments requested by the soldiers using weapons. First of all slimmed down carbine, mainly by removing excess material with aluminum castle chambers, reducing its mass by 0.5 kg. For comparison, the mass of subkarabinka CZ 805 Bren 1 A2 280 mm barrel is 3.39 / 4.10 kg (without iron sights and magazine / with a full magazine and sling), while his counterpart CZ 806 Bren 2 A2 of the same length barrel – only 2.76 / 2.99 kilograms.

Also redesigned from the cocking lever moving during the shot. The CZ 806 when voltage is disconnected from the breech and remains stationary in the conduct of fire. It also includes new mechanism of gas which decomposes to clean in a much simpler manner than in the model CZ 805 has also changed its setting number of two to three. CZ 806 has a new, folding on the right side of the flask with a plastic adjustable foot position. The latter ends with a prominent, removable from the shock.

The main difference between the first and the second version is changed Brena drain chamber. It is no longer a separate module shared with the magazine slot, the CZ 806 is it with him one. Pistol grip can be equipped with one of two straps, matching it better to hand the shooter size M and L. Bren 2 has a new, improved trigger. The designers of the CZ abandoned the option series 2-blasting. In the model CZ 806 switch the type of fire has only three settings: protected, fire a single and continuous fire.

The rifle changed the position of the manipulators by introducing two release levers mobile assembly from the rear position in which it remains after the last shot. The first is almost identical to the known M16, located on the left side, conveniently manipulated with the thumb of a hand putting slot magazine. The second is hidden on the front wall of the interior of the trigger guard. It is shaped like the letter C, the pressure on the lower edge releases the bolt carrier with a rear position, while raising his finger top allows them to be blocked at the inspection. It also includes reciprocal release of the magazine, placed in front of the trigger guard on both sides of the magazine slot.

The armed forces of the Czech Republic, which next year are going to buy the next batch of military weapons from Ceska Zbrojovka, probably decide to purchase a new variety CZ 806. Just Czech defense minister and the generals are perfectly aware that the early adoption of weapons to arm increases its export opportunities.

However, if such a decision will be made, it will mean that by the time a major overhaul, the Czech soldiers will be well until three versions rifles Brennan: CZ 805 Bren one of the chambers drain to the Czech magazines, CZ 805 Bren 1 of chambers trigger for magazines of M16 and modified CZ 806 Bren 2, in many ways different from the original model. That may create in the future a number of logistical problems associated even with the supply of spare parts. In practice, during renovations a few years, the older models will probably adapted to the latest standard.

For me, the second model Bren is an expected development. The Bren 805 rifle was originally designed for a polymer upper receiver, something that shows in its contours, which appear more well-suited to injection molding than milling. At some point in development, the material was changed to aluminum, but the receiver’s dimensions were not, resulting in an expensive and heavy assembly. The new rifle has an upper receiver apparently designed for aluminum from the start, which certainly brings the weight down, and mostly likely also greatly reduces cost. Indeed, the new rifle appears to address all of my major complaints about the 805, with the exception of the bolt removal procedure being armorer-level; no word yet on whether that has been changed. [EDIT: overlander in the comments points out that the pin holding the bolt group together is readily driven out. CZ reps had told Tim and myself that bolt removal procedure was armorer-level, and the pin has a divoted end that I had assumed was a rivet/staking. Mea culpa on that one]
