Viridian RFX45 Mounting Adapter Features The Viridian RFX45 Mounting Adapter is machined from 6061 aluminum to handle the recoil forces of duty and range use without shifting the optic s position. The hard coat anodized black finish adds wear resistance protecting the plate s surface through repeated holstering and handling. At just 0.50 ounces the adapter adds negligible weight to a Glock MOS slide while providing the correct mounting pattern for the RFX44 and RFX45 closed emitter sights. Its low profile dimensions 1.50 inches long 0.95 inches wide and 0.20 inches tall keep the completed optic mount compact and close to the bore axis. Designed specifically for Glock MOS footprint pistols this adapter lets owners mount Viridian s RFX series reflex sight without machining or gunsmith fitting. The kit includes the mounting hardware needed for installation so the plate is ready to attach straight out of the box. A properly fitted adapter plate like this one is essential for maintaining a repeatable zero when switching optics or rebuilding a slide. For Glock MOS owners running or adding a Viridian RFX45 this mounting adapter is a precise direct fit solution.
