Hello, Im new to this board and AR15 rifles in general, but after shooting a couple of my friends rifles, I seem to have become obsessed with owning one of these fine firearms. The problem is, almost all of the dealers in my area cannot get a hold of the rifle that I am interested in and the dealers that can are way overpriced. The rifle I am interested in is the Bushmaster M4 carbine with the A2 receiver, 14.5" barrel with the mini y comp and the pinned stock. I have a dealer that will do the transfer for $15 and I was wondering about some reputable online sources for purchasing this rifle. I would like to keep the price after shipping and transfer as close to $800.00 as possible. Any input or experience is greatly appreciated. Thanks for your time.
