LRRPF52, I've got a CQB-C that I played with briefly, just enough to make some brass marks on the deflector, and took apart and put back in the box. It was so tight I had to use a leather mallet to slide the lock on an off. Since I will likely never build a carbine length firearm again, I would be glad to just send it to you to let you play with if you want. It does have dedicated rails, but I don't know what gen it was, I've had it for a year or two. If you don't want it fine, I might trade it for something sometime, but because you've put up with my undereducated BS on this site, I'd send to you to have for free. This offer only applies to you, so no PM's from other people please.

I've been much happier with the VLTOR uppers, which are much beefier, but not quick change.
