I have bought a Tactical RIS hand guard for my t68 and a M203 launcher a month or so later, and as i try to mount it on the ris handguard no matter how hard i try to tighten it down there is alot of play in it. Now on the hand guard that this one replaced it worked just fine so i find this odd. Also i packed greese in the 203 shell because i have seen on here that that needs to be done but the shell will not charge, the air comes out of it as soon as i start to charge it.
