These mounts attach to the top of the receiver on your factory 10-22, allowing you to mount a red dot optic.
Not sure which optics pattern to choose? See Optics Compatibility for more information.
Note for Vortex Venom users: The mounting screws that come with your optic are too long, you’ll need some from our mounting screws page
Shield RMS vs Sig RomeoZero mounts:
The Sig RomeoZero optic is compatible with both of these mounts, but the Sig RomeoZero version of the mount is being discontinued. The Shield RMS mount is an updated version that is compatible with a larger variety of optics, including the Holosun 407k/507k.
