Light, Concentric, effective


I got this in an effort to have a Keymo mount option that had decent flash suppression and did not also increase the overall length by 3 inches. Its an excellent little device that does require timing. Make sure you have some spare 5.56 shims around because this doesn't ship with any. 5 stars if it shipped with a shim kit given it needs to be timed.

TLDR, Good, Short, Light, Rocksett and you're off to the races
