Alright, I got my build all put together but had a question before I stuck my upper on my lower. I'm gonna buy the CMMG 14.5 Mid-Length Upper w/Permanent Hider and I wanted to make sure I'm not gonna break any laws. Can I put that upper onto my lower with the pistol grip, collapsible stock and the perm hider as long as it's got the P50 in it? Or is the perm hider a no no? Or possibly do I have too many features?
