Description
The C&H Precision V4 optic mounting plate bridges the gap between the factory CZ P-10 optic-ready cut and the Holosun EPS or EPS Carry footprint, which uses the compact RMSc pattern rather than the more common RMR layout. Without a plate like this, the EPS and EPS Carry simply will not sit flush or mount securely in the P-10’s slide cut — this adapter solves that directly.
C&H Precision designs and machines these plates at their small family-owned facility in coastal Georgia. The body is machined from 6061 aluminum and finished in MIL-SPEC Type III hard anodize, which is a thicker, harder coating than standard Type II and resists wear at the contact points between the optic base and the slide. The mounting system relies on 416 stainless steel T-nuts threaded into the plate rather than simple tapped aluminum holes. The difference matters in practice: stainless steel threads hold torque more reliably over repeated mounting and dismounting cycles, and the T-nut geometry provides significantly deeper thread engagement than a directly tapped aluminum plate of the same thickness. Each plate goes through multiple quality checks before leaving the shop.
Because the hardware is replaceable rather than integral to the plate, a stripped or damaged screw or T-nut does not mean discarding the plate. The package includes the plate itself, two M3 plate-mounting screws, two 4-40 optic-mounting screws, and two 416 stainless steel T-nuts — everything needed for a complete installation.
