The new RRD-4C muzzle brake/compensator

The RRD-4C is a lightweight Muzzle Brake Compensator that not only reduces recoil by 20% and virtually eliminates muzzle rise but also REDUCES FLASH*! This one of a kind combination device gives you control over your firearm like you've never had before while only adding 1.5" in length and 2.75 oz in weight!

Since the release of the original RRD-4, we have been tweaking the design to improve muzzle control and reduce weight. The RRD-4C has cut-outs on the top sides to allow gas to vent upwards in turn forcing the barrel downwards and virtually eliminating muzzle rise with an extremely low flash signature!

Outstanding performance! Using a 7.62x39 AK has never been easier! Makes your rifle shoot super flat and the muzzle flash is almost nonexistent. Super satisfied!

This device is awesome. It does a real good job at taming recoil, and allows for fast follow up shots.
