Ray's Review of JMac Customs 4C 1/2-28 4-Port Muzzle Brake w/ KeyMount
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
