Ballistic Advantage Modern Series 5.56 Barrel Gov. Carbine - 12.5"
Chambered in 5.56 NATO, this Ballistic Advantage 12.5” 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 1/2x28, 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.

This Is What I Needed!
I bought mine before PA carried this model/length and I couldn't be happier. The fit and finish is superb! I had to dimple the barrel for the gas block ( I have a jig ) and it took a long time as that steel is HARD. I gave it a brief break-in and got great groups right from the start. I'm currently shooting it with a LANTAC Dragon, Superlative Arms gas piston system and a Fostech Echo binary trigger and the brass really flies but I can find nothing to fault about this Aero Precision (group) barrel. At the current sales price, it is a steal!
