I have a GGP 16” mid-length 1:7 twist 5.56 ar15 that I would like to trade for a 14.5” mid-length pin and welded ar15. The upper and lower is a fully ambi GGP set. It had a 15” Griffin Armament mlok rail. 50 rounds has been fired through it to sight the scope in. The light, stock, scope and mag will not be part of the trade.
