The Primary Arms Deluxe AR Scope Mount (brand part no. 9100158) is built for M4, AR-15, and similar flat-top 1913 Picatinny platforms, giving 30mm-tube scope owners a solid, no-nonsense mounting option. Made by Primary Arms, this mount uses aluminum construction with a durable matte black anodized finish, and it offers 2.52 inches of clearance between the rings for scopes with larger objective bells or turret housings. It places the center of your 30mm tube 1.5 inches above the rail, a height that works well for most AR-pattern rifles and cheek riser combinations. The mount is backed by a lifetime warranty, and Primary Arms recommends torquing the mount nut clockwise until resistance, then an additional half turn, staying within 35-40 in-lbs if using a torque wrench.
