BudsGunShop.com - muzzle break on a shotgun???

Hi Dave and welcome. No Sir. I use a similar Brake and have not had an issue, even with bird shot. Cheers and stay safe!

no the brake diameter is large enough that the slug or shot charge should not make contact. Now if it is effective and helps anything is subject to opinion. IMO it is marketing Hype I have ported choke tubes on my competition skeet gun and they dont cause any issues with plastic or lead the do develop a lot of carbon that needs to be cleaned off
