I'll start the ball rolling with this one, which is actually pretty rare. It was manufactured by AR Sales in 1969. It was known as the Mark IV. This is an early one, with a 3-digit serial number. The G.I. national match barrel was fitted to the gun at the factory as a favor to me. I replaced the original walnut stock with a G.I. fiberglass stock for ruggedness and accuracy. The action is VERY strong. I once loaded some .311 bullets I got a gun show (without miking then - never do that again), and when fired, the primers blew out of the cases, falling into the trigger housing group and jamming the rifle. However, the action held and the headspace remained the same. As an aside, the apparent selector switch lock is a dummy for the sake of appearance. It's a plastic part attached to the stock to fill in the selector switch hole. This was one of the first semiautomatic M14 clones made in this country, and cost me all of $150 when new.
Let's see what ya got!
