Midwest Industries MK2 QD 30mm Scope Mount Standard Black MI MK2 QD30SM UPC 812102035749
Product Description
The Midwest Industries® MK2 Quick Detach 30mm Scope Mount (SKU: MI-MK2-QD30SM / UPC: 812102035749) represents the apex of American engineering for modern semi-automatic tactical and competition rifles. Built specifically for flat-top AR-15 and AR-10 platforms, the MK2 series establishes a rock-solid, repeatable interface between your host weapon and 30mm variable-power or low-power variable optics (LPVOs). Engineered to deliver uncompromising return-to-zero capabilities in rapid field detach scenarios, this standard-height cantilever mount delivers immediate target acquisition, consistent eye relief, and absolute structural confidence under sustained recoil impulses.
Precision CNC-machined from billet 6061-T6 aircraft-grade aluminum, the MK2 mount is engineered to endure harsh operational environments while trimming excess bulk down to an agile 7.9 ounces. The exterior surface is treated with an ultra-durable MIL-A-8625 Type III Class 2 Hardcoat Anodized finish, providing exceptional defense against chemical solvents, aggressive field conditions, impact scratching, and atmospheric corrosion. Featuring an integrated 1.400-inch cantilever forward offset and a 1.550-inch optical centerline, this mount positions the scope at the ideal height for standard military cheek weld, naturally clearing rear backup iron sights and accommodating massive objective bells up to 56mm.
At the mechanical core of the MI-MK2-QD30SM is the patented Elite Defense quick-detach camming lever mechanism—widely recognized as one of the smoothest, most rail-friendly locking systems in the tactical industry. The lever assembly utilizes a specialized 12-sided multi-faceted adjustment nut that allows operators to calibrate exact clamping tension by hand, seating securely onto both standard Mil-Spec rails and out-of-spec commercial extrusions without tool requirements and without coining or gouging the rail surface. Furthermore, the MK2 architecture accepts Midwest Industries' modular top-cap ecosystem, giving shooters direct staging access for auxiliary 12 o'clock or 45-degree offset micro red dot sights (such as Trijicon RMR, Aimpoint T-2, or Aimpoint ACRO footprints).
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Optimized for all MIL-STD-1913 Picatinny upper receiver rails on AR-15, M4, and AR-10/SR-25 pattern rifles; fits all 30mm diameter riflescopes with up to 56mm objective lenses. CRITICAL: DO NOT bridge the mount base across the receiver rail and handguard rail. Bridge mounting introduces severe thermal deflection and rail torque during firing sequences, causing erratic zero shift. Scope ring screws must be degreased and torqued to a maximum of 20–25 in-lbs using an alternating cross (X) pattern; verify optic manufacturer maximum tube torque prior to final tightening to prevent optical tube deformation. Adjust the 12-sided QD nut by hand until firm thumb-pressure lockup is achieved; do not hammer or force the lever.
- Ensure the host firearm is completely clear, magazine removed, and chamber visually and physically verified empty.
- Clean and degrease the host upper receiver Picatinny rail slots, then unlock the patented Elite Defense QD lever by pressing the safety release lock button and pivoting the lever out 90 degrees.
- Place the mount base exclusively on the monolithic upper receiver rail, push the mount firmly forward toward the muzzle to bias the integral recoil lugs against the forward rail slot faces, and test lever closure; adjust the 12-sided tension nut so the lever closes smoothly with firm, positive resistance.
- Seat the 30mm riflescope into the lower ring cradles, set proper eye relief in your standard shooting position, level the reticle using a precision bubble level or wedge, and install the ring caps using the included Midwest Industries Optic Mount Tool.
- Evenly torque the Torx ring cap fasteners in an alternating X-pattern to 20–25 in-lbs while maintaining equal ring gap spacing on both sides; function test all firearm controls, verify throw lever clearance, and confirm zero repeatability at the range.
