Locked & Loaded

The MIDDLE (300AAC / 300BLK) is a fantastic all around ammo for the AR15 platform and only requires a barrel change on the ARs...

I'm going to have a barrel built to run the 7.62x25 through an AR for my next gun project...

The middle bullet shown above goes through THIS (which is equal in power to the AK47)... Im going to build another that uses the far left Tokarev bullet...

You bought the bullet before the gun?

I built the gun, THEN changed the caliber a few times (didnt like the way it cycled when set up for AK47 ammo), THEN built the 300AAC ammo... The 300AAC is kind of new on the scene...

Built the ammo? Why not just buy it?

When I started this project the 300AAC ammo wasnt available in the stores and the load data was very very limited. It wasnt SAAMI approved until this past Spring I think...

I blew the gun up once with some of my initial loads... It's just a science project...

Introducing the Advanced Armament Corp. 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.

Full power 115-125 grain ammunition matches the ballistics of the 7.62x39mm AK, and eclipses 5.56mm 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.


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 7.62x39 ballistics
• Provide the ability to penetrate barriers with high-mass projectiles
• Provide all capabilities in a lightweight, durable, low recoiling package

REASONS 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

This is soooo far over my head...just don't test me...please

Cool stuff but I hate hard to find ammo stuff. I'll just stick with easy to get .556.


Or this for my Big Bang fix.

Hey Dave,

I know this is like asking "How high is up" but....................how much would you think it would cost me to build a rather standard run of the mill 5.56 AR? With some of the more desirable options not just "plain Jane" mil-spec??

Been thinking of building one but the local guys have a Colt for $850 and was wondering if I should go with that or build.......whatdoyathink??

Unless you want to have a different stock or different type of handguards I'd just buy that Colt. That's not a bad deal. I could probably build you one for a little cheaper but it won't be a Colt. Now if you want it like mine with the longer handguard, magpul stock, custom trigger etc, it's probably better to build one.
