Jmac Customs RRD 2 PORT COMPENSATOR .45CAL KEYMO 5/8-24'' RRD-2C-30S-KM-4

The RRD-2C is a shortened version of JMac’s 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
• .45 Cal compatible (0.50" Diameter bore)
• KeyMo & KeyMicro Suppressor compatible
• 2.23" Long
• Added length: 1.53"
• 17-4ph Stainless Steel

• Not intended or recommend for barrels shorter than 10.5” when using rifle calibers

When testing these devices with rifle calibers, JMac 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.

Not compatible with Dead Air Ghost.
