The Ballistic Advantage Tac Gov gives you everything you want in a short .308 platform: a robust steel barrel that won't let you down and predictable accuracy that's backed by the manufacturer's sub-MOA guarantee. This is the kind of barrel you build around when you're planning a compact AR-10 that doesn't sacrifice the ballistics of a full rifle cartridge.
Machined from 4150 Chrome Moly Vanadium steel and treated with a QPQ salt bath nitride finish, this barrel sheds corrosion and maintains its dimensions better than comparable hard-chrome options. The QPQ-coated M4 feed ramp extension ensures reliable feeding cycle after cycle. A 1:10 twist rate handles the full spectrum of common .308 loads from lighter varmint rounds through heavy match ammunition.
The carbine-length gas system on this 14.5-inch barrel puts more aggressive gas pressure on the bolt carrier group, which is critical for short-barrel reliability. This shorter dwell time means the system cycles with authority and won't hesitate even when running suppressed ammunition or when conditions get rough. Real-world builds with quality carbine-gassed .308 barrels prove this configuration runs dependably when set up properly.
The Tac Gov profile is a practical middle ground—lighter than a heavy barrel but still rigid enough for precision work. Government-profile AR barrels are the standard because they give you reliable function, manageable weight for a .308 platform, and the accuracy you'd expect from Ballistic Advantage. Threaded 5/8×24 for standard muzzle devices, with a gas block journal diameter of .750 inch.
This is a bare barrel, ready to integrate into your build. Weight comes in at 38 ounces, keeping the overall platform reasonably balanced while maintaining the stiffness that matters in a larger frame rifle.
This is a bare barrel, so you'll need to source your own gas tube, gas block, bolt carrier group, and other components to complete your upper receiver. The barrel itself comes ready to install once you have those parts assembled. Make sure your gas block is sized for the .750 inch journal diameter.
Yes, when properly gassed with quality components. The carbine-length system is actually the traditional choice for shorter .308 barrels because the increased gas pressure compensates for reduced dwell time. This barrel is designed with that in mind, and real-world testing shows carbine-gassed 14.5-inch .308 builds run dependably.
Ballistic Advantage backs this barrel with a sub-MOA guarantee when using match-grade ammunition, defined as groups of 1 inch or under at 100 yards. Actual performance will depend on your ammunition, optics, technique, and overall build quality, but this Modern Series barrel is built to deliver consistent results.
No, Ballistic Advantage barrels are ready to shoot straight out of the box. You can fire it immediately without any special break-in procedure or additional cleaning before use.
