White Label Armory AR15 Barrel Features The White Label Armory AR15 Barrel is chambered in 5.56 NATO and cut to a compact 10.50 inches a length well suited to pistol-length or short-barreled AR builds where maneuverability is a priority. A 1:7 twist rate gives the barrel the stabilization needed to handle the full spectrum of common 5.56 bullet weights including heavier match and tracer rounds that slower twist rates struggle to stabilize. This versatility means the barrel is not locked into a narrow range of ammunition giving the builder flexibility in loads for training hunting or duty use. The Government profile contour adds material around the barrel for improved heat dissipation and rigidity compared to a lightweight pencil profile which helps maintain accuracy across strings of rapid fire. Designed to work within a carbine length gas system the barrel is intended for builds that need a shorter overall gas system length to match the reduced barrel length without sacrificing reliable cycling. A properly matched gas system length is critical to keeping an AR-platform rifle or pistol running smoothly and this barrel is built with that compatibility in mind from the factory. Builders assembling a short-barreled rifle or AR pistol will find the Government profile a dependable choice for durability under hard use.
