As interesting as a new caliber is to some of us, it gets better. Start thinking about a M4 with a 9"; barrel that matches the energy of 5.56mm M855 from a 16"; barrel (the standard M4 is a 14.5"). The 300 AAC BLACKOUT 123 grain ammunition matches the ballistics of the 7.62x39mm AK and has 37% more energy than 5.56mm M855 when either are fired through a short barrel. Clearing buildings, crawl spaces, vehicle work, going up ladders and seizing ships or aircraft are all tasks that have us wanting a short barrel, but getting shot at has us wanting a round that ends threats quickly. It looks like the new 300 AAC Blackout from Remington/ AAC ammunition and upper receiver is at the right place at the right time.

DESIGN OBJECTIVES
• Create a reliable compact 30-cal solution for the AR platform
• Utilize existing inventory magazines while retaining their full capacity
• Create the optimal platform for sound and flash suppressed fire
• Create compatible supersonic ammo that matches 7.62×39 ballistics
• Provide the ability to penetrate barriers with high-mass projectiles
• Provide all capabilities in a lightweight, durable, low recoiling package

REASONS [why] 7.62x39 WAS NOT CONSIDERED
Extreme cartridge taper
• Reduces reliability of feeding in AR Magazines
• Reduces Magazine capacity
• Cartridge taper induces considerably higher bolt thrust-
exacerbating the AR Bolt's weaknesses
• Requires a larger Bolt Face which reduces Bolt Locking Lug strength-
exacerbating the AR Bolt's weaknesses
Limited projectile selection
• 0.311" diameter not a common option in most modern bullets
