Elevate your shooting experience with the Island Barrel 9mm Complete Upper, a cornerstone of the DY™ line of products engineered for unmatched precision and control. Compatible with the Frames for DY9 and Frames for Glock 19 Gen 4, this complete upper blends timeless performance with modern accessibility, transforming your pistol into a precision powerhouse. Whether for home defense, range sessions, or competition, the DY™ Island Barrel Upper unlocks sharpshooter potential with every round.
Featuring the iconic Island Barrel Design, this upper reimagines a classic by shifting mass to the barrel and incorporating four top-mounted gas ports to dramatically reduce muzzle rise. The result? Flatter recoil, faster follow-up shots, and pinpoint accuracy. Designed with a fixed front sight, your aim stays true even during rapid-fire, while the lighter slide, complete with an RMR cut for seamless optic integration, minimizes flip and enhances target reacquisition. Enhanced recoil management delivers less kick, faster cycling, and effortless return to target, making every shot feel instinctive.
Choose the DY™ Island Barrel 9mm Complete Upper and experience the precision, control, and innovation that define the DY™ brand.
