I've got a problem with the KAC panels staying locked in place after shooting a couple of rounds. I know on the end of the rails it's notched so the metal clip on the panels will lock in place to prevent movement. Anyone know a fix for this when the panels are not on the ends of the rail? I figure someone else has come across this issue before. hinking.gif

Either notch the rail or get different panels.

Proper use is to run the clips at either end and trim as necessary.

Try inserting a small screwdriver under the panel clip, and then lightly prying the clip up. I used this method to lock in KAC panels on YHM rails which had no cuts in the rails for the clips to engage.

QUIB is right. If they don't want to lock in place pop up on the metal tab with a screw driver. You should even hear a "click" noise. I have never had any come loose after popping up on the tab.

I’ve had some that didn’t “click” so I omitted that from my post. But yea, your right about the “click”.

And yes, I have also had some not click too so don't toss them out if they don't make a noise You will know when they are locked in place.

Maybe on a lightweight YHM rail, but how can you click on a normal spec rail?
The KAC clip is effectively held outside the groove until a notch is present.

I had at one time the standard YHM two-piece hand guards and the screwdriver trick worked.

Yeah, those cuts look screwy too...(compare them to the upper)

Can you click a KAC cover on say a KAC or LaRue in any other spot than the notched ends?

Screwy? They were the standard for YHM four railed HG's. No different than any other.

Don't know. Never had a reason to try.

ETA: Could just be a trick that works on YHM only.

I think that is the trouble the OP is running into -

YHM appears to cut the grooves of their rails on a lathe rather than flat on a mill.
Each slot is essentially like the ends of most spec rails.

You can also try running a veru small bead-line of silicone along the inside of the rail that hugs the rail. I saw that posted here awhile back. All of my KAC panels are pretty much impossible to move once in place..never had a problem with them moving. I've used the above technique on some fake rails and it did the trick.

I originally came up with that fix and posted it here.

Some KAC panels are a bit loose on MI rails. My fix was to apply black silicone sealant to the rail panel to tighten up the fit. This will not secure the rail to the panel, just tighten it up if loose.

I just cut 1-2 notches of a cheap ladder rail cover and use it to lock the panel in place. Of course, you need a couple of empty pic rail positions to do this.
