rail cover installation
 

I got one of those KA standard rail covers for my scar, but I'm having difficulty installing it...it's the ones with those metal locking clamps at one end of the cover.
Do I just slide the thing on from one end of the rail and when it gets stuck on the metal clamp part I just force it in?
Or do I line up the clamp part with a slide and instead of sliding the thing in, I just kinda force the whole thing on from on top?

Thanks.

Slide in, when hit the metal clip, press down and hold the clip from top, slide the rest in. Done.

Got it, thanks!
