Just wanted to say hello. I stumbled onto the forum while searching the web for info and have found plenty of good info here. I have 2 AR's a Bushmaster M4 and a panther M4 both about 10 years old and completely stock so far. I have a collection of Russian shotguns that I enjoy shooting as well as various handguns and rifles including some AK's. I would like to thank all of you that contribute information to the forums and to the administration and moderators.
