Ar-15 bayonet mount picatinny rail - Pro Mag AR-15/M16 Bayonet Lug Accessory Rail PM216

I used this mount on a Bushmaster QRC rifle. It works as advertised to mount my bipod. It did take a little filing to make the screw holes line up. In general, a five minute job turned into a 30 minute job, but it does work well once it is installed. The mount has two slots for a sling. My 1 1/4 inch wide sling worked, it is a little tight, but not a problem.
