High-Quality Barrel Ideal For A Short Barrel Rifle or Pistol Build

The Ballistic Advantage 5.56 10.5″ AR-15 Barrel is an excellent option for building a short barrel rifle or even a pistol that combines the durability and strength of 4150 chrome moly vanadium steel with the exceptionally corrosion resistant salt bath nitride treatment.

This modern series barrel features a QPQ coated M4 feed ramp extension and carries all the qualities you would need for a short carbine style build.

Ideal For The Heavier Projectile in 5.56 Ammos

The Ballistic Advantage 5.56 10.5″ AR-15 Barrel features a short, 10.5″ inch barrel with a 1:7 twist rate, ideal for heavier projectiles in match grade and defensive 5.56 loads. The government profile is thin behind the gas block shelf to reduce weight but then gets larger to accommodate .750” gas blocks.

This barrel is also threaded with 1/2×28 so you can easily attach any 223/5.56 muzzle device, whether it is a flash hider or muzzle brake.

All NFA/ATF Rules Apply

You may use this barrel with a lower receiver that is a Registered SBR, Machine Gun, or Pistol. Possession of this barrel along with a Non-NFA lower receiver is Prohibited, except when installed on a Pistol configuration firearm.
