I've heard these things are a pain to strip, and that it needs cleaning every thousand rounds or so. I'll put a few hundred rounds through it this week and get cracking
The magazine disconnect is what makes stripping a pain. Remove that and it's a breeze, plus it will also improve your trigger quite a bit as well. I also think the slingshot mod
is a must have. It's easy to complete and makes the bolt stop function like it should In the first place!
