Curious to see if anyone elses RAS II fits like mine does. I just bought it recently and after installing it as per Knights instructions I noticed that it has a little bit of play to it. Is this inherent in the free floating handguards or is it particular to the RAS II. I have a CQD vertical grip installed and when I rock the grip back and forth I feel the RAS shift in the front where the bottom handguard inserts into the top handguard. I can do the same thing by just grabbing the two handguards all the way to the front and squeezing them together with my fingers. Just a very little amount of play but I wondered if it was normal. Thanks. |
| I don't think I can get them any tighter. It's not on the receiver end where the two screws are that I have the play, it's at the front sight side that it is doing it. I can grab the two rails with two fingers one on the top and the other on the bottom and sqeeze them together and get a little play where the bottom slides into the top handguard. I can actually make them click when I squeeze them. |
I didn't realize you had a separate post on this issue, so i copied my response, hope this helps:
That is normal for the area you described. For the benifit of those who don't have a RAS II in front of them to refrence, this is the area toward the muzzle, where the lower handguard is retained by hooking (more or less) into cutouts in the upper handguard section. The rear of the lower guard can either be retained by the force of the delta ring (like regular HGs for quick removal & swap to an M203), or secured by the clamp to the barrel nut. This lower section will have some play in it because regardless of the rear clamped area, the front is only hooked in. The one-piece top handguard should be absolutely rigid, as it comprises both the top rail (for optics/lasers) and the side rail. (lasers/lights) I noticed this too the first time i took mine out, but not to worry, this lower section does not have to be absolutely rigid unless your using a laser mounted on the bottom rail.

I've got mine right in front of me and cannot get anything to move. |
I don't think it's supposed to say SSS on it. The Shot Show Special was special pricing that Knights released for the RAS II (i.e. ~$276 for RAS II, VFG, and extra rail panel). |
| I cant say for 100% sure, but I have one of the earliest RAS IIs on one of my guns and have installed probably 10 SSS RAS IIs on other folks guns and I have not noticed a single difference in them. Clearly these 11 samples is a small test group to go by, but it is 100%. To be honest, the overall finish on the 10 SSS special I worked with was actually smoother than the one I have! |
Hmm. I would try reinstalling it. Here is a link for the instrctions they are much eaiser to read than the paper one that comes with the unit. quarterbore.com/library/pdf_files/rasii22243inst.pdf Good luck |

I bought my RAS II long before the SSS. The movement I refer to in the lower handguard is very very slight, but it is there. It's best noticed when you press the rifle hard into the carpet floor, with some cloth to cushion a little. Now pulling on the forwardhandle from side to side you can feel it move maybe a 32nd, or a 64th of an inch. (a little subjective however.) Tex78 |

I have the SSS too. I have noticed that I can make the front section "click" when I put the vert frip in the middle and really torque on it. This problem seems to go away the futher forward the RASII is installed. The RASII is really close to the front handgaurd cap like this but it is rock solid, no click. I didn't like how close it was getting to the front handgaurd cap as the RASII is a free floater system. I now have it installed all the way back (large gap between handgaurd cap and RASII) but with a "gasket" ,or a shim. I got matches and torr off the cover and split the cover in 1/2 by rolling it in my palms, I then cut off small, thin strips of paper and lined the front part of the RASII with it (the part that hooks the halves together). It worked perfectly, no more click. Let it be known that the click was nothing to worry about. the gap that caused this was so small I won't even guess. the only reason I put the gasket ther is because I am nothing more than an Armchair commando, so the click kinda buged me. It in no way affected the performace of the unit. The RASII is great. |
