Look into EMISSARY DEVELOPMENT Hand Brakes either their full size or mini. They are great and low profile….. Added bonus they are not 90 deg. so technically can be used on AR pistols. I tried one out I got from PA and never looked back. I used to be that guy whom put BCM angled fore-grips on, until I used Emissary’s brake…. Just spreading the knowledge when I can. P.S.A. The tinging will go away after you shoot it a bit…I think I remember you having a Centurion Arms “Sandcutter” Chrome BCG, have you used it yet and your thoughts? Kicking around picking one up with their new dual ejector bolt
