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!
Product Specs;
*When testing these devices, we found that high rates of fire such as full auto or “mag dumps” could cause damage to the device due to the excess heat, pressure, and gasses from unburnt powder on shorter barrels.
Compatibility;
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!
Additional Pictures can be found HERE!
*Reduces flash on barrels 12" and longer.
