The introduction of the 300 Blackout took the AR-15 to a whole new level in the shooting arena. If you’re not already a fan of this cartridge, take it to the range, and you will be. You can have an AR that not only performs in CQC but is an effective long-range weapon as well. To get the most out of this versatile cartridge, you need a barrel that’s up to the task. The Jacob Grey 16” 300 Blackout barrel is just what you’re looking for.
You won’t get any unneeded features with the Jacob Grey 300 blackout barrel. You get a cold hammer-forged barrel with a reliable carbine gas system. This combination means you get what you expect, the best. To make function meet reliability, the Jacob Grey barrel is designed with a little more wall so that heat is more easily dissipated, and barrel whip is kept to a minimum. We went with 4150 Chrome Moly Vanadium blanks for this 300 blackout barrel. Not only is this design easy to clean, but it’s corrosion-resistant as well. Jacob Grey stays true to the industry standard when it comes to the gas-block seat and muzzle threads. Therefore, the gas-block and muzzle device you already have will likely fit. If you’re not happy with your current muzzle device, look up any of the Jacob Grey muzzle devices or compensators.
