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 3 oz in weight! 

Product Specs;

  • Material: Military Grade 17-4PH Stainless Steel
  • Length: OAL 2.5"(63.5mm), Added length 1.5" (38.1mm)
  • Weight: 3.70 oz
  • Finish: Matte Black Nitride
  • Caliber: .360" bore will work with 5.56x45 and 7.62x39
  • Manufactured in the US and counts as 1 922r compliance part


  • M92 (PAP) Pistol and Carbine 
  • M85 (PAP) Pistol and Carbine
  • Spring and Detent required to install

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!

* Reduces flash on barrels 11" and longer

Huge improvement over the stock booster. the shipping was speedy, it came a whole day early. My gun shoots so flat it's insane.

beautiful piece, a+ fit and finish

Bought this to replace my Bulgarian 4 piece muzzle brake. This thing is a work of art. Already had the detent/pin installed, so putting this on was a breeze. If I get another AK, I'm definitely getting another product from Jmac.
