Sylvan Arms Glock 19 Gen 4 RMR Slide with Internals

The Sylvan Arms Glock 19 Gen 4 RMR slide with internals for builders who want a true one-piece solution. First, every slide starts as certified 416R stainless steel. Then advanced CNC machining creates perfect Gen 4 geometry plus a tight RMR optic cut with 6-32 bosses.

After machining, the entire slide receives a full black nitride treatment inside and out. Because nitride penetrates the steel, corrosion resistance and lubricity far exceed standard finishes. Consequently, the slide stays slick and protected even after thousands of rounds.

Next, technicians install complete Gen 4 internals: upgraded extractor, depressor plunger assembly with LCI (loaded chamber indicator), spring-loaded bearing, and channel liner. Additionally, factory-height black polymer sights come pre-installed for instant use, while the included black nitride cover plate keeps the RMR cut hidden when no optic is mounted.

Finally, every Sylvan Arms Glock 19 Gen 4 RMR slide with internals is fully assembled with a match-grade black nitride barrel and Gen 4 recoil spring assembly, then live-fire tested before shipping. As a result, you simply drop it onto any Gen 4 or compatible frame (including many P80 builds) and run it hard from day one.
