Stripped RMR window slide for Glock 17 Gen 1, 2, and 3 frames — Brownells billet build with a Trijicon RMR optic cut and a window cut that exposes the barrel and chamber area to reduce reciprocating mass. Drop-in onto the OEM lower with a standard Gen 1-3 locking block; no frame work or rail modification required.

The RMR pocket accepts Trijicon RMR Type 2 and matching-footprint optics (Holosun 407C/507C, SIG Romeo1 Pro). Iron-sight dovetails are standard Glock-pattern front and rear. Ships stripped — no internals, no sights, no barrel — so you can build with a 3CR completion kit or a full Brownells parts pack.

Features:

• Fit: Glock 17 Gen 1, 2, 3 frames
• RMR optic cut (Trijicon RMR Type 2 and compatible footprints)
• Window cut for weight reduction and visual signature
• Standard Glock-pattern iron sight dovetails (front and rear)
• Billet machining, premium black finish
• Optic mount screws: 6-32 × 7/16"; cover plate: 6-32 × 1/3"
• Ships stripped — no internals, sights, or barrel
• Made in USA by Brownells

Verify your optic ships with footprint-matched screws — we recommend the optic manufacturer's screw kit rather than generic hardware. Confirm slide locks fully into battery before live fire.
