Midwest Industries® MK2 Series QD Lever Optic Mount – Fits Aimpoint® ACRO Footprint – Lower 1/3 Co-Witness Height – Hardcoat Anodized Black Finish – MI-MK2-QDACRO1-3
The Midwest Industries® MK2 Series Quick-Detach Lower 1/3 Co-Witness Aimpoint® ACRO Optic Mount (MI-MK2-QDACRO1-3) represents a premier mechanical benchmark in professional-grade combat rifle integration, masterfully engineered in the USA to blend split-second adaptability with absolute return-to-zero structural consistency. Designed specifically to anchor enclosed-emitter tactical red dot sights to modern AR-15 carbines, defensive weapons, and sub-caliber platforms, this quick-detach mounting hub eliminates the compromise between modular flexibility and immutable alignment. While generic QD mounts are notorious for suffering internal lever binding, losing true tracking alignment across continuous mounting loops, or using low-grade clamping brackets that chew into receiver finishes under torque, the Midwest Industries MK2 platform overrides those structural flaws. This professional asset (812102035831) delivers an uncompromised high-precision baseline, serving as an exceptional primary upgrade for active law enforcement patrol rifles, defensive staging arrays, and intensive tactical training programs.
The operational core of this high-efficiency quick-detach platform is driven by a **patented premium QD lever mechanism engineered by Elite Defense**. Universally celebrated across competitive and tactical spheres as one of the smoothest, most reliable lever locking arrays in the industry, it works in perfect tandem with an innovative **multi-faceted external adjustment nut**. This specialized tool-free system allows operators to fine-tune the mount's exact cross-bolt tension in seconds, enabling it to match flawlessly with non-standard or heavily worn Picatinny rails that fall outside strict Mil-Spec tolerances. The overbuilt clamping shoe is specifically shaped to distribute massive lateral compression forces uniformly without coining, marring, or scarring the underlying finish of your weapon's receiver rail, ensuring smooth detachment and true return-to-zero reliability shot after shot.
The structural foundation of the riser is CNC precision-machined from a monolithic block of premium certified 6061-T6 aircraft-grade aluminum billet. Treated with an advanced, deep-penetrating **Type III Mil-Spec Hardcoat Anodization**, the matte black core is completely armored against chemical gun solvents, relentless carbon gas corrosion, and deep holster abrasion. Engineered to achieve a standard **Lower 1/3 Co-Witness geometry (1.60-inch optical centerline height)**, this mount places your red dot sightline at the perfect natural height for standard AR stock combs, leaving your physical backup iron sights neatly visible within the lower third of the viewport window. Weighing a negligible 3.00 ounces, this American-made mounting layout delivers supreme mechanical authority, ensuring your high-performance optic remains locked, ready, and completely immovable under the violent kinetic recoil of rapid defensive strings.
Includes: (1) Midwest Industries MK2 Quick-Detach Lower 1/3 Co-Witness ACRO Optic Mount (6061-T6 Aluminum Body, Patented Elite Defense QD Lever Assembly, Matte Black Anodized), and (1) Proprietary Midwest Industries Optic Fitting and Adjustment Cardboard Staging Tool.
*Quick-Detach Lever Tensioning & Alignment Guidance: The MI-MK2-QDACRO1-3 features a tool-free adjustment system designed to achieve perfect clamp lockup. When initial fitting occurs on your 1913 Picatinny rail, ensure the QD lever is fully open before rotating the multi-faceted nut to take up excess slack. The lever should close with firm, crisp thumb pressure; if forcing the lever requires extreme strain, back the nut off one click to prevent over-insertion stress. Never coat the internal ACRO alignment indexing lug or the lever assembly tracks with heavy wet grease, as it will collect unburnt powder grit and impair the mechanism's self-locking detents.
Key Features
- Patented Elite Defense QD Lever: High-performance quick-detach mechanism delivers ultra-smooth operation and instant, one-handed optic removal and reattachment.
