Saw them at ehobby some days ago. Looks like a decent mish-mash of ACM parts, and they're priced the same as the standalone ACM Larue RAS' out currently. The only thing it's missing is a gas block. Though, I did find it strange that the 9" RAS didn't come with an outer barrel and flash hider.

Surely after all this time an ACM company should make a Larue ris with the notches on the last segment of RIS to allow a knights style rail cover to fit

?

Hopefully these don't suck at mounting like the old ACM ones did. I'm getting a 11.0" soon.

I just wanna know if they fit onto KJ M4's.

Getting one for my STAR MBK - might do a Review once it gets here.
