This is the low fixed mount for a Comp M1 M2 or M3 scope. Has thumb screw for mount/dismount. Nothing fancy but cheapest mount for that scope. Perfect for mounting Aimpoint on the forward handguard scope mount of an M1 Carbine. Would be too low for an AR with a standard front sight (get the higher one).
Pros: Solid well made military grade piece
Cons: none
