Optic Mount Plate for GLOCK® 17 19 19X GEN 1-5 for RMSc Red Dot like 407K 507K For Sale

TSA® AP-00091 Rear Sight Dovetail Optic Mount Plate for GLOCK® 17 19 19X Gen 1-5 — RMSc / 407K / 507KPRODUCT DESCRIPTION

The TSA® AP-00091 Rear Sight Dovetail Optic Mount Plate allows compatible non-optic-ready slides to accept compact red dot optics without permanent slide milling.

Designed for slides using standard GLOCK®-pattern rear sight dovetail dimensions, the mount replaces the factory rear sight and provides a mounting surface for compatible RMSc / Holosun K-pattern optics, including the Holosun® 407K, 507K, and EPS Carry.

The plate is constructed from high-grade aluminum with a corrosion-resistant black finish. Its precision-machined design provides secure fitment and dependable optic support under recoil while maintaining a lightweight profile.

This mounting solution is intended for compatible standard-width GLOCK® slides and aftermarket slides using the same rear sight dovetail geometry. It is suitable for range, sporting, competition, duty, and personal-protection configurations where legally permitted.

Important: Compatibility depends on the slide's actual rear sight dovetail dimensions, not the brand name alone. Verify your slide and optic footprint before ordering.
