Wonderful for my sbr 556 - Midwest Industries 7.25in Combat Rail T-Series One Piece Free Float Handguard

Fits well for my 7.5 in barrel in 556 if you want a flush fit with suppressor I used this hand guard for a 7.5 barrel then used a YHM full size Srx muzzle device has enough clearance for suppressor without the use of shims or accu washers. This only worked for 556/223 barrels barrel type was .223 wildy tribe defense barrel 7.5
