Should I worry about that little nick on my crown? I installed a PWS FSC556 Suppressing Compensator and noticed that the some finish was coming off the barrel after 400 rounds through it. So I took it off to wipe clean the muzzle to see how much finish was taken off. The pics below is after cleaning. That’s when I noticed a little nick on crown. I’m going to go back to the stander A2 flash hider as I didn’t see a major gain with the PSW FSC 556. Is the nick something to worry about?    |

I just had to cut off a permed PWS 556. I couldn't take the noise and blast of it, and I wanted to put a silencer mount on the barrel anyway.
The finish didn't come off of mine with 1400 rounds through it. It is a BCM barrel. 
I can't imagine not being able to feel the benefit of the brake though. It's obvious to me that the recoil is reduced... it's just not worth the noise and blast. (I wouldn't worry about the finish being gone.... my barrels usually have a little CLP left over in that area after cleaning anyway.) |

This is the S&W factory installed barrel. I didn't notice much reduced recoil. this is a carbine gas system. It did not reduced as much recoil as the KKF brake I had on another gun. To be fair the other gun is a 20" rifle gas system, But compared to other 20" AR with the same gas system, the KKF did an excellent job and made it feel like a 22LR gun. With the FSC 556, it reduced the recoil, just not as much as I expected. KKF Brake  |
