Weapon Outfitters is known as the destination for 13.7″ AR-15 barrels. Their latest 13.7″ offering is a Ballistic Advantage Performance Series barrel that has the Hanson Profile and a pinned gas block. These barrels are a solid value at $220 when you consider the specs and the pinned low-profile gas block.
These barrels are only available at Weapon Outfitters and are being offered for pre-order since the initial batch sold out so quickly. The upcoming batch is already en route so the wait won’t last long (neither will the barrels). You may also want to check out Weapon Outfitters’ reasonable muzzle device pinning services to bring this barrel to a legal 16″. Check out the new barrels at Weapon Outfitters.
