The Lone Wolf Dusk Complete Upper with RMR Cut for Glock 19 Gen 3 includes a DUSK19 profile slide made of 17-4SS. Front and rear serrations on the slide provide ease of chambering and press-check. The slide is reflex sight-ready with the DUSK19 optic cover plate included, which is compatible with both Trijicon RMR/SRO and Holosun 407/507/508 (Non-K Models) footprints. Additionally, this slide includes a \u8531? co-witness or suppressor height Night Fision Stealth Series sight with a Tritium insert for clear sight vision from DUSK to dawn. The upper also includes a 416 stainless-steel nitride coated non-threaded barrel with the DUSK 19 profile. The hood pocket and lateral ribs reduce bearing surface for faster cycling and coating wear resistance. Swapping your OEM slide or finishing your pistol build with the DUSK19 Complete Upper enhances both the shootability, versatility and reliability of the platform.
