CH Precision GLOCK MOS to Holosun EPS EPS Carry Adapter Plate Matte Black GL EPS UPC 616943735086
Product Description
The C&H Precision V4 MIL/LEO Adapter Plate (SKU: GL-EPS / UPC: 616943735086) delivers an ultra-rugged, duty-ready mounting interface specifically engineered to bridge standard full-size GLOCK Modular Optic System (MOS) slides with the enclosed-emitter Holosun EPS and EPS Carry reflex optics. Factory stamped steel or thin MIM adapter plates often suffer from loose tolerances, thread stripping, and shearing under high-round-count recoil impulse. C&H Precision eliminates these critical failure points by providing an exact-tolerance CNC billet solution that drops directly into the GLOCK MOS slide recess, creating a rigid, low-profile mechanical bond that withstands heavy duty cycles and competition demands.
Precision-crafted in Coastal Georgia on multi-axis HAAS CNC machinery, each GL-EPS adapter plate is milled from 6061-T6 aircraft-grade aluminum billet to aerospace-grade dimensional tolerances. The entire surface is treated with a resilient MIL-A-8625 Type III Class 2 hardcoat anodized black finish, yielding superior resistance against galvanic corrosion, aggressive slide friction, carbon fouling, and harsh bore solvents. Integrated recoil lugs and precision thread pitch engagement prevent optic shift, distributing reciprocating lateral forces across the entire plate surface rather than relying exclusively on shear stress against mounting screws.
Engineered with an ultra-thin deck profile averaging under 0.100 inches, the C&H Precision GL-EPS keeps the optic center axis as close to the pistol bore line as physically possible. This low mounting height accelerates target acquisition, eliminates excessive mechanical offset (height-over-bore), and preserves lower third or absolute co-witness visibility when paired with appropriate suppressor-height or selected factory-height iron sights. Designed for patrol officers, armed professionals, and discerning concealed carriers, this adapter plate includes all required high-tensile mounting hardware and Vibra-TITE threadlocker for immediate armorer bench staging.
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Compatible with all standard double-stack factory GLOCK MOS slides (G17, G19, G19X, G34, G45, G47, G20, G21, G22, G23, G40 MOS) in Gen 4 and Gen 5 configurations. CRITICAL: NOT compatible with slimline Glock 43X MOS or Glock 48 MOS slides (requires dedicated slimline adapter plate GLX-EPS). NOT compatible with standard Trijicon RMR, Leupold DPP, or Aimpoint Acro footprints. Slide-to-plate screws must be torqued strictly to 12-15 in-lbs; optic-to-plate screws must be torqued strictly to 10-12 in-lbs. Always utilize low/medium strength threadlocker (Vibra-TITE VC-3 or blue Loctite 242/243); allow 24 hours of chemical cure time prior to live-fire staging.
- Ensure the host firearm is completely clear, magazine removed, and chamber visually and physically verified empty.
- Thoroughly clean and degrease the GLOCK MOS slide pocket, plate mounting screw holes, and plate mating surfaces using isopropyl alcohol or dedicated non-chlorinated solvent; ensure all surfaces are completely dry.
- Place the C&H Precision GL-EPS adapter plate squarely into the MOS slide cutout, ensuring flush mechanical engagement without cant or forced seating.
- Apply a sparing drop of threadlocker to the provided slide-to-plate screws, hand-thread evenly, and torque using an inch-pound torque wrench in an alternating cross-pattern to exactly 12-15 in-lbs.
- Seat the Holosun EPS / EPS Carry optic onto the plate recoil lugs, install the optic-to-plate fasteners with threadlocker, torque evenly to 10-12 in-lbs, apply witness marks on screw heads, and perform full dry-fire and slide-cycling function checks.
Key Features
- HAAS CNC Machined 6061-T6 Billet: Precision cut from high-tensile aircraft aluminum for tight tolerances and structural rigidity under recoil.
- MIL-A-8625 Type III Hardcoat Anodize: Premium matte black anodized surface provides maximum resistance against abrasion, holster friction, and environmental corrosion.
- Ultra-Low Profile Deck Architecture: Sub-0.100" mounting height minimizes bore-axis displacement and enhances co-witness sight picture versatility.
- Integrated Recoil Lug Engagement: Custom-machined bosses seat securely into the Holosun EPS/EPS Carry chassis to eliminate optic shear stress and zero drift.
- Complete Armorer Hardware Kit: Ships with required metric/SAE high-tensile Torx fasteners and threadlocking compound for turn-key bench installation.
- 100% Made in the USA: Designed, prototyped, and manufactured in Coastal Georgia for rigorous duty and law enforcement applications.
