I just purchased my first AR after 30+ years of not carrying an M16 and I'm reaquainting myself with the bugger. I've watched some youtubes on building them. Larry Potterfield has a good series on the tools required and the application of them. I had a Springfield M1A for years but tough times had me selling it in the late 80's. I never thought about an AR for myself until Pelosi started spouting gun control.
So spill on the AR, what brand or what internals if it was a custom build. Give us the gun porn man! And I missed firing my m16, though the AR I currently have is way over gassed and has 0 padding on the stock so after about 60 rounds my shoulder starts to complain. Hence the reason I'm doing this build (with an adjustable gas block). But yeah, the smell of the rounds, the feel of shooting it, brings back memories and is just fun to shoot.
