Works with bcm govt - Rock River Arms AR0010B HandGuards A2

works with bcm govt profile upper that doesnt come with handguards (20 in barrel, rifle length gas). good finish, quality. looks and feels great. its the round-slimmer style ones. not oval like dpms. let me tell you though, free float is a much better way to go. i never believed it , but found out that i can flex a barrel 10 moa with plastic handguards like this.... yes. even a bcm. it makes a cool retro but with inconsistency like that ill never consider it a “shooter”.
