AR15 Pistol Barrel at a Great Price

If you’re looking at building an AR15 pistol, you might be surprised at how much you have to pay for less gun per inch than standard-length guns.  Diamondback Firearms offers this high-value barrel to complete your next AR15 pistol build.  It features 4150 CMV steel with black nitride finish to prevent wear and corrosion, and a 1-8 twist for broad ammunition compatibility for 5.56 NATO cartridges.  If you’re in need of a handguard that fits just right for this length, try our 9″ SPEAR M-LOK handguard.
