A Tacfire 10.5" 5.56 NATO pistol build kit handles the heavy lifting so you can assemble a compact, capable firearm without sourcing parts piecemeal. This unassembled kit includes everything needed to complete a functioning 5.56 pistol—barrel, bolt carrier group, handguard, buffer tube, and both upper and lower parts kits—leaving you to supply only a lower receiver to finish the build. It's a no-fuss starting point for builders who want the core components in one box.

The 10.5" barrel strikes a practical balance for a pistol-format AR: short enough for handling in tight quarters, long enough to generate meaningful velocity from 5.56 NATO rounds. The low-profile gas block and pistol-length gas tube are sized appropriately for the shorter barrel length, and the included A2 flash hider helps manage muzzle signature. Black anodized finish across the components means your finished gun will have a uniform appearance out of the box.

Whether you're a first-time AR builder looking for a guided path or an experienced gunsmith filling out your collection, this kit removes the paralysis of part-matching and sourcing. Just add a lower receiver—the regulated component—and you'll have all the mechanical pieces ready to pin, stake, and assemble. The M-Lok handguard gives you modern accessory real estate for lights, foregrips, or rail systems if you want to expand later.
