Forward Controls Design GB19T 9mm 4.5" Threaded Barrel
Glock 19 Gen 3-5 / 19x / 45 - DLC Black

Engineered in partnership with Killer Innovations, the GB19 Match-Grade Barrel delivers uncompromising accuracy, flawless reliability, and premium craftsmanship for shooters who demand more from every round. Built using Killer Innovations’ renowned Single Point Technology (SPT)—a rifling method so precise it requires 120 individual cuts per bore—the GB19 achieves near‑perfect groove uniformity with less than 0.00001" deviation. The result is a barrel that shoots flatter, groups tighter, and performs consistently shot after shot.

Designed to mirror the elite Killer Innovations Velocity series, the GB19 maintains the same match‑grade standards while adding subtle Icon Innovations touches, including a minimalist Cygnus logo and a uniquely styled thread protector. Whether you’re upgrading your carry gun, optimizing a competition build, or enhancing your duty setup, the GB19 delivers the accuracy, durability, and confidence you need.
