This kit does not include a lower receiver or a magazine.

The creator of the M16 was four years old when the creator of the .45 ACP passed away. But if the timeline had allowed Eugene Stoner and John Browning to collaborate, then they might just have come up with the very same AR pistol you now want to build.

Save yourself the inconvenience of hunting down every last part that goes into an AR-45. When you order this unassembled parts kit by TacFire (a major American AR part and accessory distributor), you’ll have everything you need to start building (minus the lower, which is classified as a firearm by the federal government, and the magazine as well).

Life’s not much fun when you’ve got a gun but no ammo. Check out our wide selection of .45 ACP in stock!
