In order to use this device with a suppressor, it must be installed by a professional - to ensure it is properly mounted and aligned. Do NOT shoot without checking alignment with bore rods. JMac Customs is not responsible for any damage to the suppressor, or any injury resulting from improper installation. Some firearms are NOT suitable suppressor hosts, just because you can thread this muzzle device on, does NOT mean it is safe to use.

The RRD-2C is a shortened version of the RRD-4C by removing the 2 smallest ports creating a more compact package!

At 2.23" it still adds 1.53" and can be permanently attached to a 14.5" barrel to achieve 16" OAL

Written by Tony Arnott on Nov 28th 2021

Jmac customs makes the coolest am accessories, the RRD muzzle breaks work great as a break and flash suppressor, personally have used and am a fanatic about many of their products

JMAC is Whatsup!

Written by Phillip Manofsky on Apr 18th 2020

This muzzle break is really nice. Machining and finish is high quality. Whether it is their muzzle breaks or their railed stock adapters, JMac Customs is probably my favorite company for aftermarket AK parts. I love this brand!
