Product description

16 Inch .300 Blackout Barrel by AT3 Tactical

A 16 inch .300 Blackout barrel makes swapping to a heavier hitting cartridge in your favorite rifle simple. This 4150 CMV barrel features a medium profile, providing plenty of support for mounting a suppressor, without feeling cumbersome in the field. It also gets a black nitride finish for corrosion resistance, and has M4 feed ramps for optimal reliability.

This barrel uses a .750″ diameter gas block, plus a Pistol length gas tube, both of which you can snag here at a lower, bundled cost. If you’re looking to start fresh with a complete upper assembly, check out our selection of upper and handguard combos! For this barrel, we’d recommend a handguard at least 12 to 15 inches long for shooter comfort, and space for accessories.

I've fired 7 rounds thru this barrel and every case came out with a 'double shoulder' like the chamber wasn't reamed correctly. No problem with rounds going IN, but they come out with a second shoulder bump about 1/3 down.

We take quality control very seriously, and we'd like to work with you to resolve this issue. Please reach out to our customer service team and we'll be happy to assist you further.

I used the barrel with at3 upper receiver and bcg. The first time out sighting it I shot 5 groups of five at 50 yards using AAC amo. I stcked each group with only one flyer. Performed perfectly now we will se on the long game if it holds up.

AT3 Tactical · Thanks for the review! We're glad you liked it!
