Chambered in 5.56 NATO, this Ballistic Advantage 10.5” barrel is an excellent 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 a 1:7 twist rate. The barrel is made from 4150 Chrome Moly Vanadium and has a 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 10.5" Barrel

Awesome barrel that does not break the bank.

Can't go wrong with a B.A barrel

by -

I have several B.A barrels from 7.5-18". So as soon as I seen P.A had them in stock and on sale. You can just take my $$$.

Awesome quality and fast shipping


My new Ruger 556 pistol barrel had bad threads so I just bought a better quality barrel rather than deal with the hassle of sending my firearm back hoping for a replacement. I'm in TX and PA shipped this sweet barrel asap and it arrived in 2 days. I had no idea PA was TX based. I will be ordering parts from you guys from now on!!!! Plus this barrel was on sale!

First BA barrel, not my last.

This barrel is gassed excellently. Ejection is perfect with h2 buffer, cycles and locks back on both steel + brass ammo, even in very cold (0 F). I will update once suppressor is out of jail! I have not done definitive accuracy test, but with Sierra 77g, it is near moa.
<br>I ordered a BA 8" 300 blk based on my positive experience so far, both barrels show the same QC, waiting for their 308 next. I would like to see them pre-dimpled for gas blocks, but I know not everyone does.

Great Barrel for the money


Used this for a pistol build and shot great! Only cost me $84

<br>Awesome service by PA.
