Additional information

additional info

The individual purpose and way of using a weapon requires an individual approach to selecting the individual components of which it is composed. It is possible to choose between a medium-heavy barrel with excellent rigidity or a lightweight version if you prefer lower weight and high mobility comfort. The gas system available in two lengths is outstanding. For barrels in lengths 10.5 "-14.5", we use Carbine length. For barrels in lengths 16.5 "and 18" the distance from the chamber to gas hole is 2 inches longer – Mid length, to keep full increase of the speed of the bullet and thus increasing long-range stability and accuracy. Long barrel with short gas hole distance just does not make sense. Depending on the purpose, the muzzle device is selected. The rifle is equipped with a muzzle device with the maximum effect of the VULCAN series. To reduce the weight of the weapon we also developed the MICRO series.

The handguards meet the standards of the so-called free float handguards and are designed as a tactical carriers and also serve as a solid and reliable grips. They are fixed to the barrel nut and allow it to oscillate freely. They are made of hardened aluminum and coated with a thick layer of hard anodizing, even when delivered in CERAKOTE® coating. For the purpose of attaching accessories, it is possible to choose between a standardized rail system STANAG 4694 NATO (PICATINNY 1913 compatible) or M-Lock slots combined with a NATO top rail. User comfort is enhanced by consistent beveling and rounding of sharp edges. It also significantly extends the life and reliability of repetitive clamping of tactical accessories. Rounded and bevelled edges can withstand friction and mechanical loads far better. It is also important that both the weapon and its components keep a new look for as long as possible.
