C&H Precision Optic Mounting Plate for Glock Gen 4/5 to Steiner MPS Footprint

C&H Precision Optic Mounting Plate for Glock Gen 4/5 to Steiner MPS Footprint

Securely bridge your Glock Modular Optic System (MOS) slide with the rugged enclosed-emitter Steiner MPS reflex sight using the C&H Precision V4 Steel Optic Mounting Plate. Factory MOS adapter plates and standard aluminum aftermarket solutions often suffer from flex, minimal thread engagement, and sheared screws under sustained recoil impulses. Engineered to resolve these vulnerabilities, the C&H Precision V4 plate delivers an ultra-low profile, rock-solid steel mounting foundation purpose-built for duty officers, defensive shooters, and competitive marksmen who demand unwavering zero retention and durability from their red dot optics.

Proudly designed, machined, and quality-inspected in coastal Georgia, each plate is precision-machined from solid steel on high-end HAAS CNC centers to exacting dimensional tolerances. At the heart of the V4's reliability is C&H Precision’s patented stainless steel T-Nut system. By replacing traditional shallow tapped holes with independent T-Nuts, the system delivers an industry-leading six to seven full threads of engagement—more than double the thread depth of standard mounting methods. Furthermore, this modular hardware architecture ensures that if a screw or thread is ever compromised, it can be replaced quickly in the field without rendering the entire adapter plate useless. Treated in a non-reflective matte black finish, the V4 plate delivers severe-duty dependability across full-size and compact Gen 4 and Gen 5 Glock MOS pistols.

Features

Patented Stainless Steel T-Nut Architecture:
Utilizes C&H Precision’s patented stainless steel T-Nut locking system, providing an industry-leading six to seven threads of engagement to resist screw shearing and prevent optic loosening under heavy cyclic recoil.

Fully Field-Replaceable Hardware:
Eliminates the cost and downtime of replacing the entire mounting plate if threads are stripped or damaged; simply swap out the individual T-Nut and screw assembly to restore factory torque integrity.

Heavy-Duty CNC-Machined Steel Build:
Precision-machined from high-strength billet steel on HAAS CNC centers, eliminating plate deformation, warping, and flex under hard field use and one-handed slide manipulations.

Dedicated Steiner MPS Interface:
Engineered specifically for the clamping footprint of the Steiner MPS (Micro Pistol Sight), ensuring precise longitudinal and lateral containment for consistent return-to-zero.

Broad Glock Gen 4 & Gen 5 MOS Fitment:
Fits standard-width Glock MOS slides including the G17, G17L, G19, G21, G22, G23, G26, G34, G35, G40, G41, G45, and G47.

Ultra-Low Profile Optical Centerline:
Machined to the thinnest safe envelope to position the Steiner MPS as close to the bore centerline as possible, preserving natural presentation and enabling co-witnessing with appropriate suppressor-height iron sights.

Durable Matte Black Protective Coating:
Finished in a corrosion- and scratch-resistant matte black coating that blends seamlessly with factory Glock slide finishes while resisting sweat, bore cleaners, and moisture.
