Blast Deflector muzzle attachment available


Even so compensators and flash hiders are quite popular among sport shooters, they also have some disadvantages. If you are lined up on a shooting range next to each other, the neighbor will get the full muzzle blast sometimes including particles and smoke residue. This is not only awkward but could also be dangerous.

When shooting from the prone position, the muzzle blast will raise dust, dirt and even small stones. This is not only irritating, it also blocks the shooters vision and can lead to jams. In these cases, the B&T Blast Deflector is the perfect solution. It is installed on all Rotex-IIA or NATO/Rotex-V compatible flash hiders and compensators (.223/5.56mm and/or .308/7.62 mm) in less than five seconds. The B&T Blast Deflector slows down the hot gases leaving the muzzle and prevents lateral dispersion. Thus any endangerment of neighboring shooters as well as the dispersion of dirt is prohibited. Due to its weight of a little more than 200 gram the B&T Blast Deflector helps to reduce the muzzle movement when shooting , enabling the shooter for fast follow up shots. The B&T Blast Deflector does not reduce the sound signature.

B&T polymer lower for USW-320

The perfect upgrade for the SIG Sauer P320!
The revolutionary USW concept from B&T is now also available for the P320. The practical polymer conversion kit transforms a normal P320 (full-size or compact) in less than two minutes into a USW-320 with integrated stock. Just transfer the trigger group, the slide and the magazine release onto the USW-320 frame. The USW-320 lower equals the full-size P320 lower, so 17 round magazines (and bigger) can be used.
Due to the integrated folding stock, accuracy and range is improved significantly.
