Thanks Mr. Rumore, I believe it is an early one... SN in the 60's
I am really surprised my BRO actually found a custom guy and a well researched one at that. I did not know he had it in him. He is ex army airborne and is familiar with the AR so I guess wanting a good one should not be unusual at all.
I am lookin foward to shooting it for sure!
I only got into the rifle seen after the first AWB and was a pistol guy mainly for years. The rifle scene is as bad as far as wanting "one more"
