TacFire
The TacFire AR build kit with 5.56x45mm NATO 7.50" barrel gives you a compact, manageable platform for pistol-caliber or short-barrel AR builds. This kit brings together the core components you need to assemble a capable AR—whether you're piecing together your first rifle or adding a short-range, high-mobility option to your battery. The 7.50" barrel strikes a balance between portability and velocity retention in the 5.56 NATO cartridge, making it a solid choice for home defense, close-quarters training, or an agile truck gun.
TacFire specializes in accessible AR components, and this kit reflects that philosophy: you get a complete parts package in black finish that works with standard AR platform receivers and assemblies. The short barrel length keeps overall dimensions compact without sacrificing the reliability and modularity that make the AR platform so popular. Whether you're a builder looking to experiment with shorter configurations or someone who wants a tighter, easier-to-handle 5.56 upper, this kit handles the heavy lifting.
Assembly requires basic gunsmithing knowledge or a qualified builder's help; this is parts, not a finished firearm. Pair it with a stripped lower receiver and you'll have a rifle tailored to your specific use case. The 5.56 NATO cartridge gives you factory ammunition availability and proven ballistics, while the compact profile means easier handling in tight spaces.

This kit contains the upper and barrel components; you'll also need a stripped lower receiver and assembly hardware to complete a functioning rifle. Assembly should be performed by someone with AR gunsmithing knowledge or by a qualified gunsmith.
The short barrel is optimized for close to medium range work and maneuverability rather than long-distance precision. It's better suited for home defense, training, and shorter-range field use. For hunting, consider what game and distance you're targeting and whether a longer barrel might serve you better.
This kit is designed for the AR platform, which is widely standardized. Check compatibility with your specific lower receiver, as some custom or proprietary designs may have fitment considerations.
The kit includes the barrel and upper components. Refer to the detailed product specs or contact our team for a complete component breakdown, as kits can vary in what's included.
