I have a Knight RAS forend I put on my M4 about 6 to 8 years ago. It has a fair amount of wobble on the bottom piece. This is very noticable when I have my vertical fore grip attached. It doesn't affect how the gun shoots but I notice it... Any way to quick fix it to keep it from moving short of running a drywall screw through it.? I notice my Surefire rail doesn't do this. Has Knight corrected this in newer models..? Any help on this is appreciated.... |
This is surprising and unfortunate. My M4 RAS fits tight and doesn't have any wobble what so ever. |

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. |
is this all it does? why was it made as a separate item? |
| 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? |

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. |
