[ARCHIVED THREAD] - Questions about Knight's Armament M4 rail system

Posted: 10/24/2004 1:47:05 PM EDT

I bought a slightly used one today at the fun show, but it didn't come with instructions of any kind, and I can't figure out how to remove the rib panels, or how to mount it correctly. I am more worried about damaging it than anything else, so I didn't experiment with it too much before logging on.

Any help would be appreciated.

Is it the RAS or the RIS? The RAS has a locking tab and screw at the rear of the top handguard rail portion.

The panels are added or removed by depressing the center of the metal tab so that it spreads way from the rail notchs.

The rails are cut for the metal locking tab at either end of the rail section.

OK, I got the panels off, but I still can't slide the larger portion of the RAS under the handguard retention ring.

Remove the screw at the rear that retains the hook. Allow the hook to hang loose and lower the RAS onto the rifle while you hold the delta ring back. Make sure the hook slips over the gas tube and then under the barrel nut. After everything is in place, put the screw back in and make it real tight. Some loctite wouldn't hurt.
Hope that helps.

I got the RAS, three 11-rib panels, a side sling adaptor, and handguard removal tool for just under $375, including tax.

Hmm seems a bit high to me for a used system with the side sling adaptor. New RAS units go for around $300...

Used RAS: $250
Three rib panels: $45
Side sling adaptor: $30
Handguard removal tool: $20

He charged me tax because I had to use my debit card, otherwise the total would have been $345.

Considering how bad the rest of the show was, I was happy with this deal.

Just so you know the RAS comes with three panels! So you paid retail for for the RAS. The sling mount is a fair price...

Ouch. he hosed ya on the panels. what a dog. I picked mine up from a fellow poster at lightfighter, it was nint witth 3 panels for $250.

if it makes ya feel any better, I saw a guy at a fun show awhile back with a Used RAS with the VFG and he was asking $450. I laughed when he told me the price. takes all kinds. but you'll be happy with it. good solid piece of kit that will serve you well.
