Arisaka Defense Mk2 OMM Optic Mount - Fits EOTECH EXPS Holographic Sights, 1.93" Height taller stance - Cerakote Flat Dark Earth Finish - OM2-EXPS-193-FDE
Product Description
Equipping a modern defensive carbine, personal defense weapon (PDW), or gas-piston short-barreled rifle (SBR) with an EOTECH® holographic sight reveals an immediate ergonomic bottleneck: a standard lower 1/3 co-witness factory mounting height. Low-set optics force shooters into an aggressive, hunched-over cheek weld that stresses the cervical spine and slows down situational scanning. If you attempt to transition to target lines while wearing tactical communication headsets, full gas masks, or passive night-vision goggles (NVGs), the low clearance of a standard base completely blocks your visual path. The **Arisaka Defense® Mk2 OMM Optic Mount (OM2-EXPS-193-FDE)** completely shatters these head-down boundaries, elevating your holographic window to an upright, natural **1.93-inch height center line** straight from your workbench layout.
Precision CNC-machined in the United States from a solid block of certified, domestic **7075-T6 structural aircraft-grade aluminum alloy billet**, the monolithic framework of the Mk2 Mount provides extreme cross-axis stiffness and unyielding zero-retention security under violent recoil cycles. The entire chassis is treated with a beautiful, wear-resistant **Cerakote® Flat Dark Earth (FDE) finish protective layer**. This high-grade ceramic-composite shield actively repels trail moisture, carbon baking, and abrasive scratching while blending cleanly with earth-tone furniture patterns on your armorer's bench. The advanced structural layout incorporates a rock-solid **dual-clamp interface profile** engineered to lock firmly onto standard 1913 Picatinny rails with immense clamping force.
In high-speed competitive dynamic multi-gun fields, tactical training loops, or low-light passive night-vision tracking operations, the elevated physics of the **850067813583** platform yield an exceptional operational edge. Elevating the EOTECH EXPS platform to a 1.93-inch height centers the visual plane perfectly with a natural, heads-up posture, boosting peripheral awareness and speeding up target transitions. The specialized modular design allows armorers to attach optional, integrated **Mk2 auxiliary accessory arms** directly to the front or rear of the mount block. This means compact backup red dots or magnifier flips can be anchored directly to the optic chassis, ensuring a unified structural assembly that cuts out redundant rail clutter.
*Armorer Bench Notes & Technical Field Assembly Guidance: The Arisaka Defense OM2-EXPS-193-FDE Mk2 mount arrives factory-completed with all rail-clamping attachment hardware on your workbench. CRITICAL FITMENT & OPTIC CONFIGURATION LAWS: This specific mount block features an elevated Picatinny rail section tailored natively to accept **EOTECH EXPS series holographic sights** (EXPS2, EXPS3) and matching quick-detach base footprints. It will *also* host standard XPS series sights, but because the XPS lines lack the built-in factory riser of the EXPS, an XPS sight will sit significantly lower than the intended 1.93-inch tracking target height. **Armorer Workbench Installation Sequence:** Before mounting, verify the host long gun is completely unloaded and cleared. Position the Mk2 base onto your upper receiver's Picatinny rail slots, ensuring it bridges securely clear of your handguard interface. Apply a minimal drop of medium-strength removable blue threadlocker to the side clamp fasteners. **Torque Drive Parameters:** Tighten the heavy-duty side rail fasteners incrementally to exactly **50 in-lbs** using a calibrated torque wrench tool. Pro-Tip Continuity Guidance: Do not over-torque past 55 in-lbs to prevent marring your receiver rail slots. Once anchored, slide your EOTECH EXPS unit directly onto the mount's top Picatinny rail segment and lock the factory quick-detach lever down firmly, ensuring a rock-solid, wobble-free interface downrange.*
