We are the only ones who managed to launch and successfully sell of own product, which has found dozens of satisfied users. The first series was designed on the basic performance of about 120 m/s (394 fps). In the second generation due to many improvements we could supply this weapon to users with muzzle velocity about 150 m/s (492 fps) and the possibility of using the original folding stock, without limitation in battery location.
