thanks for the warm welcome, i'm in the process of building a lightweight AR on a budget, and the plethora of information this website has to offer is astonishing. at one time, i was the proud owner of a bushmaster ar, rock river ar, glock 22, springfield ultra carry 1911, mossberg shotgun, walther p22 and sig p229. currently, i own the p22, and mossberg, but am excited to refill my inventory.
