(R)ecoil (R)eduction (D)evice (2)ports (C)ompensator (28)1/2-28 threads (S)lim (9)mm

A SLIM & COMPACT version of our ever so popular RRD-4C. The RRD-2C is a shortened version of our popular RRD-4C muzzle brake. The RRD-2C was created by removing the 2 smallest ports from the RRD-4C, creating a more compact package while still maintaining the ability to mitigate recoil.

Product Specs:

  • 1/2-28 Threads
  • 10mm Bore
  • 17-4ph Stainless Steel
  • Black Nitride
  • Bore machined for 9mm projectiles
  • Not intended or recommended for barrels shorter than 10.5” if used with rifle calibers (see below)*

*When testing these devices with rifle caliber ammunition, we found that high rates of fire such as f“mag dumps” could cause damage to the device due to the excess heat, pressure, and gasses from unburnt powder on shorter barrels.

*This will require a crush washer for most applications, including KP-9 and AK-V.
