Colt
Overview
The Colt M16 Upper Group features a stripped upper receiver designed for AR-15 builds, featuring a 20-inch barrel length that optimizes accuracy and muzzle velocity. This configuration typically utilizes a rifle gas system, which provides reliable cycling and minimizes recoil for smoother operation. You'll often find this upper in builds chambered for 5.56 NATO, making it ideal for those who prioritize precision and performance in their shooting experience.
