Ballistic Advantage Modern Series 5.56 Barrel Gov. Carbine - 11.5"
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 1/2x28, 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.

Ballistic Advantage 11.5" AR 15 barrel

I can not get a grasp on how fast PA shops so fast. I had the tracking number a couple hours after ordering my parts I needed for a build. The barrel is great, no blemishes or marks or gouges. I have not got to get to the range because of my work. Working 7 days a week for the last 2 and a half months does not give me time to do anything I want to get done. But I will always buy from PA because they ship incredibly quick and answer your questions and inquiries in a reasonable time. Great job PA. Best in the business.
Excellent as expected it's a Ballistic Advantage

I honestly wanted to buy a gucci barrel from Christenson or Sons of Liberty. But I couldn't find anything in stock that was reasonable so I decided to buy this for my next build. I figure if it is good enough for Aero Precision, it is good enough for me.
