5.56 Nato 11.5'' 1-7 Hanson Carbine Lopro Chrome-Line Thread

The Ballistic Advantage 5.56 NATO 11.5" 1-7 Hanson Carbine Lopro Chrome-Line Thread barrel is purpose-built for shooters who need a short, reliable barrel for AR-platform rifles configured as SBRs, pistols, or other NFA-registered firearms. This cold hammer-forged barrel combines Ballistic Advantage's proven Hanson profile with chrome-lined bore durability, making it a solid choice for compact carbines that see regular use at the range or in the field.

Built from chrome moly vanadium steel with a manganese phosphate finish, the barrel arrives with a pinned low-profile gas block already installed—no additional gunsmithing required. The 1-in-7 twist stabilizes a wide range of 5.56 ammunition, from lighter varmint rounds to heavier match and duty loads. The M4 feed ramp extension ensures reliable feeding, while HP and MPI testing confirms each barrel meets Ballistic Advantage's quality standards before it ships.

The threaded muzzle (1/2x28) accepts industry-standard suppressors, muzzle brakes, or flash hiders. At 26 ounces with the gas block included, this barrel keeps your build balanced without unnecessary weight. Fair warning: Hanson barrels are engineered to work with standard direct-impingement gas systems and are not compatible with aftermarket piston conversion kits. Also, NFA rules apply—this barrel is legal only when installed on a registered SBR, machine gun, or pistol-configured lower receiver. Pairing it with an unregistered rifle lower is prohibited.

Whether you're building a short-range fighting carbine, a legal pistol, or working within NFA regulations for a registered short-barreled rifle, the Hanson profile offers the accuracy and durability that Ballistic Advantage is known for, without the premium cost of their match-grade offerings.
