Tried out this muzzle brake by JL Billet on a .308. Before I had Precision Armament's M4-72, the cat's pajamas of brakes in terms of performance.
PA's brake does reduce felt recoil to a gentle soft nudge that was most welcome and impressive but had the blast of a miniture howitzer. I felt like doubling-up on foam inserts and muffs was not enough with that plus the concusive shockwave became enough to relocate your spleen to a random place. So I tried out this other brake. I was most pleased. It has a well thought out design that not only looks great but is enough to tame the recoil without excessive gasses or flash. It has only a 15° back angle in the first chamber then less each slot after that before the exit, with each tilting down (directs muzzle to fight upward tendency). They put cut-outs in places that most likely aid in the reduction of pressure by diverting the gasses via interupting the walls to not give a place to linger. The top center channel is cut out and has a groove inlayed to channel what does escape upwards out and away with some downward force. Holes milled on top and in the face reduce pressure further.
I'd venture to guess if one were to compare the M4-72's performance to this one it would be 90% vs 75% reduction in recoil. I felt no sharp harsh thrust in the body as without a brake on the 18" barrel but a good firm push back, just not as soft as what the M4-72 did; yet none of the obnoxious blasting out, and eve...
