Product Description
The Ballistic Advantage Performance Series 11.3-Inch 5.56 NATO BA Hanson Profile Barrel (BABL556032F) is a precision-engineered barrel assembly designed specifically for compact AR-15 pistols and short-barreled rifles (SBRs). Featuring Ballistic Advantage's proprietary BA Hanson profile, this barrel eliminates sharp shoulders and redistributes weight to optimize balance, mitigate barrel whip, and maintain rigidity under rapid firing schedules without adding unnecessary weight.
Precision-machined from 4150 Chrome Moly Vanadium (CMV) steel, the Performance Series barrel undergoes a Quench-Polish-Quench (QPQ) Nitride finish process inside and out. This deep corrosion-resistant treatment hardens the surface, drastically reduces friction, and extends bore life beyond traditional chrome lining. Featuring a 1:7" twist rate for stabilizing heavy defensive and match 5.56x45mm cartridges (62gr to 77gr), the 11.3-inch length offers an ideal balance of compact maneuverability and reliable dwell time.
Every Performance Series BA Hanson barrel comes complete with a factory-pinned low-profile gas block and a nickel boron (NiB) coated M4 feed ramp barrel extension for flawless feeding. High-Pressure Tested (HPT) and Magnetic Particle Inspected (MPI), the Ballistic Advantage BABL556032F barrel delivers sub-MOA accuracy guarantee potential and duty-ready performance for custom tactical AR-15 staging.
