I picked up this brake to test for an upcoming SBR (short barrel rifle) build and wanted to test if what I heard about the brake was true. Well, it is. Pros––-greatly reduces the perceived noise level for the shooter and it reduces the blast to those on your side. Cons––-slightly more perceived recoil. There was very little and statistically insignificant difference in bullet performance but the data is posted below.


Chrono Data:

62gr HP Silver Bear 223

Birdcage-2741fps. 1034 ft/lbs of energy
Claymore––2733fps. 1028 ft/lbs of energy


I ran this on my PSX as well and the results were pretty much the same FWIW....
