C&H Precision V4 MIL/LEO Glock MOS Adapter Plate for Holosun 407K/507K
Aftermarket 6061 aluminium adapter plate with stainless hardware that replaces the factory Glock MOS plate and carries the Holosun K footprint, so a 407K, 507K, EPS Carry or another K-footprint sight can be mounted on a standard MOS slide. Fits the Gen 4 and Gen 5 MOS cut on the G17, G19, G34, G45, G47 and the rest of the MOS line. Does not fit the Gen 6 optic cut or the slimline 43X and 48 MOS, which take K sights directly.

Every firearm this threads onto, resolved
Not a list the maker typed out: the answer comes from the interface this part needs and the mounts each firearm exposes, so it stays right when either one changes.
- The reverse lookup on every part in the catalogue
- Interface standards, platforms and fit overrides
- The same answers through the API and the MCP server
Requires a signed-in GunSpec account on the Studio plan. The answer is computed per firearm, so it is not part of the public record.
