Diamondhead t-brake - Diamondhead T-Brake 7.62 Muzzle Compensator Black 3207

I put this brake on my Remington 700 SBS ACC 308, I'm very impressed! Felt recoil was almost non existent, I put 40 rounds through it first day. I looks awesome as well! If I had anything negative to add it would just be the fit. The back end has a taper kind of flat on the sides, maybe for using a wrench? This just takes away from the custom fit/ look. I would definitely recommend this product.
