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.

Rock solid performer.

My first BA barrel, picked it up on sale so I didn’t expect to much from it. What I found out is this is a very accurate barrel. More accurate than I am. I was getting 1.6 inch groups @ 100 yds shooting on a sandbag. Tight fit in my Radical upper and fit and finish appears fantastic. I really cannot say anything negative about this barrel. I don’t see how you could do better for the cost. It is every bit as accurate as my DD 10.3 inch barrel.

This bad boy shoots 0.9 inch groups with surplus ammo.

The first and finish of this barrel is top-tier for sure. The barrel looks amazing and has zero inspections on the finish. Threads are perfect and so is the extension. I have five of their barrels and I have had zero problems with them and find them quite accurate too (for their purpose). Best bang for the buck, no doubt. I highly recommend them.

Great barrel for the price. I'm using this in a blaster I built. Not sure about accuracy. Honestly I don't really care. This is my 3rd BA barrel. Never had an issue with them. Great price and service from PA, as always.
