Sub MOA Accuracy Guarantee – See Below!

All NFA / ATF Rules Apply – See NFA tab for details.

Ballistic Advantage 8.3″ 9MM Modern Series barrel (1/2×36 Threads) is machined from 4150 Chrome Moly Vanadium steel with a QPQ Corrosion Resistant Finish and 1/2-36 x .400 full profile threads. Because it is designed to work with both Colt/RR and Glock style AR builds, it’s a great barrel choice. It works with with standard mil-spec uppers. However, there are also dedicated 9mm upper options that work. Keep in mind that it requires the use of a unique magwell conversion (Colt/Rock River style) with UZI mags. If you want to use Glock mags a dedicated 9mm lower is needed.

Also, 9MM on an AR15 platform operates by blowback. This means you don’t need gas block or gas tube. Ballistic Advantage 9MM 8.3″ Modern Series (1/2×36 Threads) is threaded 1/2×36 instead of 1/2×28. The barrel also has integrated feed ramp and barrel extension. Lastly, the manufacturer suggests dropping a 9mm round through the muzzle device before installing a muzzle device.

This barrel is a perfect match to an Aer0 Precision AR15 Upper Receiver. Be sure to stretch your shipping dollar, and see our other AR15 products. Arm or Ally is proud to team up with Aero! Since they make their products in house, they offer a great value without the extra costs. So, be sure to check out our Aero Precision Bolt Carrier Groups, and upper receivers.
