This is surprising and unfortunate. My M4 RAS fits tight and doesn't have any wobble what so ever. |

yea they offer the "sas" lower portion as a seperate option. It has a screw and fingers that snug up against the barrel nut just like the upper portion has.

Mongo,
I don't mean to insult you in any way, and I expect that you've checked these, but I thought I'd throw them out there just in case: 1. You're sure the bottom piece is mounted the right direction? 2. The wobble is on the whole bottom piece and not just the VFG? My KAC VFG wiggles loose from time to time. It's a shame, my KAC RAS fits very snugly. HTH. |

I have both the RAS and the oider RIS system on two of my rifles. The RAS is brand new has a little side to side play but the RIS old and beat up is tight as can be. I was told that it would be the other way around.

I'm having a different problem with my RAS. For some reason it doesn't fit on my new DPMS carbine. Does the Knight's RAS only fit on crabines with a triangular handguard cap? That's where my pproblem seems to be. The leaf spring doesn't fit under the lip of the circular cap. Any thoughts?

The field expedient method (read cheap) is some heavy duty black plastic tie wraps. They need to be at least 11.5" long or longer. I found some at Ace Hardware that fit in the grooves on a standard picatiny rail and are thus low profile and out of the way.

Mine (fairly beat up) had a slight wiggle that I tried to tighten up with folded up
strips of aluminum foil along the mating surfaces. Worked pretty well until I just decided to get the SAS lower rail. Now it's nice and snug!

IT'S AN ISSUE OF TOLERANCES.
THE CULPRIT IS NOT THE KAC HANDGUARD BOTTOM RAIL, NECESSARILY. IT IS OFTEN AN OUT OF SPEC FOREND CAP. DO A FEW MUZZLE STRIKES WITH THE AID OF A VERTICAL GRIP AND A PERFECTLY GOOD FOREND CAP BECOMES OUT OF SPEC. THIS IS WHY THE UK-SAS ASKED KNIGHT'S TO COME UP WITH THE PREVIOUSLY MENTIONED BOTTOM RAIL FOR THEIR M-4'S. WES GRANT M.S.T.N. |
