I Pride my Ammo on the top quality of powder we’re using. Our 300 black out ammo is made within my opinion the best powder on the market period. This powder is specifically designed around the 300 cartridge, and not a magnum pistol powder like most others use. With a copper fouler and flash suppressor inhibitor, this is by far the cleanest and best functioning ammo you’ll ever run.  You’ll also seeing some very impressive accuracy from this product.

At American Patriot Ammo, we believe in producing top quality ammo with a focus on training applications. By using only the cleanest powder, it has allowed us to bump our velocity without pressure spikes. What that means for you is reliable rounds down range and a much cleaner firearm at the end of the day.

This product is loaded in New never fired de-milled 556 brass.
There maybe a few different head stamps in this lot of subsonic ammo, but never the less we inspect and gauge everything for top quality.

Our ammo is then loaded on new commercial grade automated machines. Powder is measured with precision metering equipment that provide the most reliable and consistent powder charges on the market.

Quality Check:

Before our ammo ever sees the end-user, we hand inspect 100% of the product with chamber check gauges to insure the product meets SAAMI spec chambers.

Loaded ammunition is shipped via FedEx or UPS Ground.
