EOTech HHS UNITY I Holographic Sight EXPS3 0 with G33 3x Magnifier and UNITY FAST Mounts Black HHS1 FTCU BLK UPC 672294601241
Product Description
The EOTech® HHS UNITY® I Complete Holographic Hybrid System (SKU: HHS1 FTCU-BLK / UPC: 672294601241) integrates the battle-proven EXPS3-0 Holographic Weapon Sight (HWS) and the precision G33 3x Magnifier onto factory-supplied UNITY Tactical FAST mounting hardware. Engineered specifically for professional end-users, tactical law enforcement, and dynamic carbine competitors, this hybrid package delivers uncompromised close-quarters speed alongside rapid mid-range target identification and precision shot placement across variable operational envelopes.
Built to withstand extreme duty conditions, the EXPS3-0 optical engine is encased in a nitrogen-purged aluminum core protected by a ruggedized 7075-T6 aerospace aluminum roll-bar hood, providing submersion sealing down to 33 feet (10 meters). The accompanying UNITY FAST Optic Riser and FAST FTC OMNI magnifier mount are CNC-machined from billet 7075-T6 aluminum and treated with MIL-A-8625 Type III Class 2 Hardcoat Anodizing for superior abrasion, chemical, and environmental resistance. Premium multi-coated anti-reflective glass lenses within the G33 magnifier preserve light transmission, edge-to-edge optical resolution, and absolute reticle clarity under harsh ambient lighting.
By elevating the optical centerline to 2.26 inches above the rail, the HHS UNITY I encourages an erect, heads-up shooting posture that dramatically reduces cervical strain, accelerates visual target acquisition, and provides seamless clearance when operating with night vision goggles (NVGs), gas masks, or plate carriers. The revolutionary Flip-To-Center (FTC) mechanism completely eliminates the bulky outboard snag hazards of legacy flip-to-side designs by stowing the magnifier directly within the receiver’s central profile below the primary optic sightline when disengaged.
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Directly compatible with true MIL-STD-1913 Picatinny rails on AR-15, M4, AR-10, SR-25, and modern tactical rifle platforms. CRITICAL: Requires approximately 8.35 inches of uninterrupted rail space. Never bridge optic or mount clamps across the upper receiver-to-handguard junction. Torque the UNITY FAST clamp fasteners to 35 in-lbs using a calibrated torque wrench. Do NOT overtighten. Verify proper EXPS3-0 quick-detach cam tension prior to live-fire zeroing.
- Ensure the host firearm is completely clear, magazine removed, and chamber visually and physically verified empty.
- Clean and degrease the receiver MIL-STD-1913 rail slots, checking for finish burrs or foreign debris.
- Mount the UNITY FAST Optic Riser to the receiver, secure the EXPS3-0 onto the riser clamp, and adjust the quick-detach cam lever tension nut until firm lockup is achieved without binding.
- Install the G33 magnifier into the UNITY FAST FTC OMNI mount ring, torque the ring screws evenly in an alternating X-pattern to 13–15 in-lbs, seat the mount directly behind the primary optic, and torque the rail clamp screw to 35 in-lbs.
- Perform a complete function check: cycle the FTC magnifier pivot arm between deployed and stowed positions to ensure positive detent engagement, focus the diopter ring to your dominant eye, verify reticle illumination across daylight and NV settings, and proceed to zero at your designated operational distance.
Key Features
- Integrated 2.26-Inch Optical Centerline: Delivers rapid heads-up target acquisition optimized for night vision pass-through aiming, plate carrier clearance, and minimal neck fatigue.
- Revolutionary Flip-To-Center (FTC) Technology: Drops the G33 magnifier cleanly below the EXPS3-0 sightline within the weapon profile, completely eliminating outboard snag points and off-axis weight distribution.
- Battle-Proven EXPS3-0 Holographic Engine: Features a true 68 MOA circle with a 1 MOA center aiming dot, projecting a parallax-free holographic reticle that remains operational even if the front objective window is shattered.
- Comprehensive NV Compatibility: Features 20 daylight brightness settings and 10 dedicated night vision settings compatible with Gen I through Gen III+ night vision systems.
- Billet 7075-T6 CNC-Machined Hardware: Premium UNITY Tactical mounts treated with MIL-A-8625 Type III Hardcoat Anodizing for maximum structural rigidity and hard-use durability.
- Tool-Free Magnifier Centering: G33 provides precision elevation and azimuth centering dials and an adjustable diopter ring for razor-sharp visual clarity.
