The Second Amendment. It is our favorite amendment, and we want you to celebrate it just as much as we do. That’s why we’re offering you nothing less than Winchester’s high-quality military-grade 5.56x45 ammunition. It’s just what needs to fill any AR’s empty chamber!

This cartridge is loaded to the military’s M193 specifications, which is another way of saying it’s loaded to the most common specifications for the 5.56x45. Its 55 grain full metal jacket projectile will (A) not attract a magnet, (B) leap out of a 20” barrel’s muzzle at a velocity of 3,180 fps, and (C) not initiate terminal expansion upon striking a soft medium. When you’re just roughing up inanimate range targets with a semi-automatic firearm, you can’t do better than the good old FMJ.

Brand new reloadable brass cases? Completely noncorrosive Boxer primers? Check and check. This ammo’s cases weren’t polished to a fine shine after they were heat treated, but that only affects their cosmetic appearance.
