JMAC really designed this muzzle brake for recoil reduction.

by JAVI50L, Verified Owner from FL, United States Written on September 5, 2024
JMAC really designed this muzzle brake for recoil reduction. The difference between the stock A2 birdcage and the JMAC RRD-4C is like day and night during rapid fire or double taps. It will affect your zero after installation, plus is a key mount suppressor ready as a bonus.
Pros:
  • Great design & sturdy build
Cons:
  • kind of heavy
Best Used for:
  • competition
Would recommend: Yes

Great brake

by Ray, Verified Owner from TX, United States Written on September 10, 2023
Solid product per usual when buying JMac. The brake works flawlessly to reduce recoil and allows Keymo capable devices to connect quickly. While shooting I did not notice any flash. The brake is on the long side but I have it on a 18” SPR so OAL does not bother me. This device did not come with shims so you will have to purchase a set.
Pros:
  • Reduces recoil and muzzle flip
  • Nice finish and fit
Cons:
  • None
Would recommend: Yes
