Colt Carbine 5.56, all stock except theres a magpul rear flip up which was $54.99, monstrum drop in quad rail $34.99 $12.99 vertical grip, bought the rifle at gun show for $1100, put 200-300 rounds through it at the range. I have two of them built the same way, both are dead nuts accurate to the flip up peep sights. Ready for range out of the box (comes with original box no pictured).
