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. 

*Can be permanently attached to a 14.5" barrel to achieve 16" OAL.

Product Specs:

• 5/8-24 Threads
• KeyMo & KeyMicro Suppressor compatible
• 10mm Bore
• 2.23" Long
• 17-4ph Stainless Steel
• Black Nitride*Not intended or recommended for barrels shorter than 10.5” (see below) 

*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.
