About the YHM 5.56 low-profile muzzle brake
YHM's 3 Chamber Low Profile Muzzle Brakes offer great recoil reduction, increasing recovery time on target. Their low profile design allows a gas block with an inside diameter of 0.75" to be installed and uninstalled without the removal of the Muzzle Brake. The product's small outside diameter is great when pinning and welding the Muzzle Brake on a 14.5" barrel. Since it allows both the gas block and the handguard to be installed directly over the Muzzle Brake.
Muzzle device length is 2.225" w/.155" crush washer - 2.38". Length added to barrel is 1.755" (on barrels with 0.6" threads).

Perfect for a pinned brake
I bought this to pin onto my 14.5” barrel to keep my barrel at a 16” legal length. This brake worked perfectly for its purpose. As a word of advice: use the crush washer they provide. I reused my old crush washer because it was easier to time but it flares past the brake and now my gas block won’t easily come off. I could get it off, but it would probably scratch the inside of the block in the process.
