Here's mine with one of Tacticool22's free float adapters used to attach a delta ring. I just used a quad rail gas block on mine. The handguard end cap had a lot of play which let the handguard move around, but I put a 10/32x1/2" SHCS through the gas tube hole and it doesn't move at all, now.






I am just waiting for some MOE rail sections I ordered so I can remount my MBUS on the MOE handguard. It's also going to get a Magpul ACS stock so it matches the AR I'm building.
