Advanced Armament Corp. is proud to introduce the 300 AAC BLACKOUT (300BLK). This system was developed to launch 30 caliber projectiles from the AR platform without a reduction in magazine capacity and compatible with the standard bolt. Initially a complete 9″ PDW upper will be offered as well as a complete barrel assembly, and 3 types of 300BLK ammo.


Full power 123 grain ammunition matches the ballistics of the 7.62x39mm AK, has 37% more energy than 5.56mm M855, and 9% more than 6.8 SPC TAP 110. In fact, from a 9 inch barrel, the 300BLK has more muzzle energy than 5.56mm M855 from a 16 inch barrel. When 300 BLK is used in a 16 inch barrel, it has 23% more energy than 5.56mm M855 from a 16 inch barrel – with much higher-mass projectiles for a more dramatic effect on the target. Or choose subsonic cartridges for optimal use with a sound suppressor – 220 grain Sierra OTM (open-tip match) bullets vastly outperforms a 9mm MP5-SD in penetration and long range accuracy.

    I wonder if anyone has made the suggestion to the military about converting to the .300 BLK. Too logical but it would only require their armorers to change the barrels out. I’m Still looking for the best deal I can get on a .300 upper along with a suppressor to go with it.

    How embarrassing. The Russians had this sort of technology 40 years ago. In the “land of the free” we’re just getting to it, and I’m sure the mountains of federal paperwork and “permission” to build it were miles high.

    The great irony is developing weapons and concepts that have been on the world stage for decades is nearly impossible in the so called free market of the good old USA. What a shame. The Kalashnikov, tool of oppression, is the benchmark for combat rifles in the “free” world.

    Gee and I was correct,the 7.62X39 was and should have been THE round for the U.S.A.
    But the NIH syndrome took over and now this.
