Sylvan Arms Glock 19 Gen 4 Complete Custom Slide – RMR Cut – Black DLC – GL19G4SK
The Sylvan Arms GL19G4SK (UPC: 811313033483) is the "ready-to-run" flagship upgrade for the Glock 19 Gen 4. While many custom slides require the separate purchase and installation of small parts and sights, the SK model is a 100% complete upper assembly minus the barrel and recoil spring. Precision-machined from a solid billet of 17-4 stainless steel and treated with a high-performance Black DLC (Diamond-Like Carbon) finish, this slide offers superior surface hardness and reduced friction, ensuring your G19 cycles reliably under the most demanding conditions of 2026.
Designed for the modern shooter, the GL19G4SK features an integrated Trijicon RMR footprint optic cut, allowing you to direct-mount the industry's most popular red dots. Unlike the "PK" version, the "SK" comes pre-installed with front and rear iron sights, giving you an immediate aiming solution right out of the box. The slide also includes aggressive front and rear cocking serrations for enhanced weapon manipulation and press-checks. With all internal components (firing pin, extractor, safety plunger, etc.) professionally installed at the factory, this is the ultimate "plug-and-play" solution for upgrading your Gen 4 Glock to a professional tactical standard.
Includes: (1) Sylvan Arms G19 Gen 4 Custom Slide, (1) Pre-installed Internal Parts Kit, (1) Set of Installed Sights, (1) RMR Cover Plate, and (1) Red Dot Adapter Plate. (Does not include barrel or recoil spring).
