I think a major problem, so few of us are allowed to own automatic weapons. The same goes with weapons with less then a 16in barrel. In my state(CT), it is also illegal to own an AK.
I live in Enfield Connecticut, so you can look it up. Determine if its to far for you.
I don't have an M4 per say. I have a carbine though. My friend's have M4s. One is a Stag and a Colt. The Colt in identical to a M4 short of full auto. I don't think the Stag has the larger handrails of the M4. The colt also has a nice Aimpoint Red Dot sight.
There is a range on private land I goto a few minutes away. Its pretty secluded. I tend to go durning the day as I work 3rd shift. I've been pretty going every week now that I own my own AR15. You are more then welcome to send some rounds down range with my rifle.
I'm sure if a few other CT people are interested, we could make a trip to this range without the "rule" of local gun ranges.
