Midwest Industries® MK2 Series Non-QD Fixed Optic Mount – Fits Aimpoint® ACRO Footprint – Ultra-Low Profile Height – Hardcoat Anodized Black Finish – MI-MK2-ACROL
The Midwest Industries® MK2 Series Fixed Low-Profile Aimpoint® ACRO Optic Mount (MI-MK2-ACROL) represents a premier mechanical benchmark in structural rifle optics integration, masterfully engineered in the USA to deliver absolute structural rigidity for enclosed-emitter red dot sights. Purpose-built to interface with the revolutionary Aimpoint ACRO footprint, this fixed mount platform is optimized for hard-use firearms where compact stealth and structural consistency override the need for rapid quick-detach manipulation. While generic aluminum reflex mounts are notorious for shifting zero under hard impact loops—and often rely on weak cross-bolts that shear under intense field strain—the Midwest Industries MK2 unibody architecture fundamentally shifts survival limits. This premium component (812102035978) acts as an unyielding tactical foundation, functioning as an exceptional primary asset for duty-vetted patrol carbines, tactical defensive shotguns, and low-profile submachine gun staging setups.
The structural foundation of this high-efficiency mounting engine is CNC precision-machined from a solid block of premium certified 6061-T6 aircraft-grade aluminum billet. Treated with an advanced, deep-penetrating **Type III Mil-Spec Hardcoat Anodization**, the mount easily shrugs off relentless carbon gas scouring, abrasive field handling, and harsh environmental humidity. Moving past traditional low-tier mounting tabs that splay out under torque stress, the MK2 platform integrates an ultra-tough **4140 heat-treated steel alloy cross-bolt clamp system**. This heavy-duty clamping core generates monumental lateral clamping force across any standard Mil-Spec 1913 Picatinny rail, guaranteeing repeatable, repeatable return-to-zero tracking bounds that remain entirely immune to the violent reciprocating slap of heavy 12-gauge shotgun shells or high-velocity rifle recoil pulses.
The true operational highlight of this American-made milestone lies in its ultra-low height profile and minimized structural mass. Designed specifically to drop your optic down as close to the receiver rail as mechanically possible, the Low configuration establishes an optimized cheek weld on firearms featuring flat comb stock lines, entirely bypassing excessive height-over-bore trajectory liabilities. Precision-engraved with crisp alignment indicators, the mount ensures an immaculate visual profile that flows seamlessly with your optic's chassis. Weighing a featherlight 2.20 ounces, this rugged mount delivers absolute mechanical authority, shipping complete with a custom **Midwest Industries Optic Installation Tool** to achieve flawless torque values right out of the box.
Includes: (1) Midwest Industries MK2 Fixed Low ACRO Optic Mount (6061-T6 Aluminum Body, Matte Black Anodized), (1) 4140 Heat-Treated Steel Clamping Block assembly, Integrated Torx Hardware Fasteners, and (1) Proprietary Midwest Industries Optic Installation & Adjustment Tool.
*Torx Hardware Fastener & Picatinny Rail Torque Guidance: The MI-MK2-ACROL mount requires a clean, debris-free interface with your 1913 Picatinny rail. To ensure absolute return-to-zero performance and prevent structural thread stripping, tighten the main 4140 steel cross-bolt fasteners to a maximum torque value of 35 in-lbs using the enclosed tactical tool. Never use liquid thread-locking compounds on the internal ACRO optic wedge clamp screw; instead, rely on dry factory friction alignments to lock your enclosed red dot securely onto the mount's integral indexing lug.
Key Features
- Optimized Aimpoint ACRO Fitment: Engineered to natively index with the Aimpoint ACRO P-1, ACRO P-2, and Steiner MPS footprints without requiring adaptive plates.
- Ultra-Low Profile Geometry: Positions the optic base flush against the receiver rail, ideal for tactical shotguns, sub-caliber carbines, and hunting platforms.
- 4140 Heat-Treated Steel Clamps: Industrial-grade steel clamping shoe locks down relentlessly onto Picatinny rails to eliminate lateral or forward mount shifting.
- 6061-T6 Aircraft Aluminum Base: Monolithic CNC precision-machined aluminum block core balances high-velocity structural mass with duty-grade impact armor.
- Type III Hardcoat Anodized Shield: Deep matte black chemical finish shields the underlying alloy against saltwater corrosion, mud abrasion, and harsh solvent damage.
- Proudly Sourced & Built in the USA: Manufactured entirely in America by veteran technicians, backed by Midwest Industries' comprehensive limited lifetime warranty.
