The National Firearms Act regulates the configurations of some firearms assembled with barrels under 16” long. Know the NFA laws in your state before purchasing this item.
Chambered in 5.56 NATO, this Ballistic Advantage 11.5” barrel is a great option for building a short barrel rifle or even a pistol. This modern series barrel features all the qualities you would want for a short carbine style build. It features a carbine length gas system for optimal reliability with the commonly used 62-grain projectiles which are also optimal with the 1:7 twist rate. The barrel is made from 4150 Chrome Moly Vanadium and is fully salt bath Nitride finished inside and out for long-term durability. The government profile is thin behind the gas block shelf to reduce weight but then gets larger to accommodate .750” gas blocks. Threaded 1/2×28, you can easily attach your favorite .223/5.56 muzzle device whether it is a flash hider or muzzle brake. If you are building a high-quality AR-15, you can’t go wrong with the Ballistic Advantage Modern Series 5.56 barrel.
