Luth-Ar
The Luth-Ar BL-F11-7 5.56mm Government Profile barrel is a no-nonsense upgrade or replacement barrel for AR-15 builds and restorations. Built to mil-spec Government Profile dimensions with a 11.50-inch length, it's compact enough for short-range work, home defense, or pistol-caliber platform experimentation while maintaining the standard profile that pairs with most existing handguards and uppers. The CMV (Chrome Moly Vanadium) steel construction delivers the durability and accuracy expected from a duty-grade barrel, finished in manganese phosphate for corrosion resistance and a classic mil-spec appearance.
Whether you're assembling a pistol-length AR, building a compact truck gun, or swapping out a worn bore, this barrel gives you the specs serious shooters and builders rely on. Government Profile barrels are the standard in tactical and military rifle development, so you're getting proven geometry rather than an experimental profile. CMV is the time-tested material for high-volume shooting and harsh conditions—easier to work than stainless steel, tougher than basic steel, and forgiving of the kind of abuse a working rifle takes.
The manganese phosphate finish won't turn heads on a competition rifle, but it does the job it was designed for: protecting bare steel without the fussiness of other coatings. If you're swapping barrels on an existing upper receiver, make sure your upper's chamber is compatible with 5.56mm ammunition before installation. This is a bare barrel with no gas tube, handguard, or other components included—you're just getting the precision-rifled tube.

Government Profile is the standard barrel profile used by military and law enforcement AR-15 rifles. It's slightly tapered and thinner than heavier profiles like Pencil or Criterion, making it lighter and easier to handle while still delivering reliable accuracy. Most existing AR-15 handguards and upper receivers are built to accommodate Government Profile barrels.
CMV (Chrome Moly Vanadium) is a proven choice for mil-spec AR barrels. It's tougher than plain steel, easier to manufacture and maintain than stainless steel, and handles high-volume shooting and adverse conditions well. It's the material choice of military and law enforcement builders for a reason.
You receive the bare barrel only—no gas tube, carrier, handguard, or installation hardware. It's a replacement or build component; you'll need an AR-15 upper receiver and appropriate gas system components to complete the assembly.
An 11.50-inch barrel is short and handy for close-quarters use, training, and truck guns. Velocity and terminal performance in 5.56mm will be reduced compared to longer barrels, so consider your intended use and ammunition carefully.
