TacFire AR-15 Lower Parts Kit / A2 Grip (Made in the USA)

The TacFire AR-15 Lower Parts Kit with A2 Grip is a complete collection of small components engineered to build or repair the lower receiver of an AR-15 platform rifle. This made-in-the-USA parts kit includes every critical internal component—trigger assembly, hammer assembly, selector, bolt catch, and fire control group elements—required to assemble a functional lower receiver. The A2 pistol grip included in this kit represents the standard ergonomic control interface for AR-15 platforms and delivers consistent handling characteristics familiar to shooters across military, law enforcement, and civilian training environments.

This kit contains precision-machined springs, pins, and detents that manage the firing sequence and mechanical reliability of the rifle. The trigger pin, hammer pin, and bolt catch roll pin work in concert with their corresponding springs to ensure consistent reset and positive engagement. The disconnector and selector assembly govern fire mode control, while the pivot pin and takedown detent system provide structural integrity and field-stripping capability. Each component is manufactured to dimensional tolerances that allow for reliable fitment in properly finished lower receivers and upper assemblies.

Operators building custom AR-15 rifles, armorers managing fleet maintenance, and enthusiasts performing lower receiver repairs rely on complete parts kits to avoid purchasing components individually. The flat trigger guard configuration accommodates standard gloved shooting and is compatible with most aftermarket furniture. This kit is ideal for those constructing duty rifles, home defense builds, or range guns where baseline reliability and proven component geometry are priorities.

AR-15 lower parts kits vary in component quality and material finishes. This USA-manufactured option consolidates the small arms that typically require sourcing from multiple suppliers, reducing assembly time and ensuring parts compatibility. Proper lower receiver finishing and fitting remain the shooter's responsibility; this kit supplies the mechanical internals necessary for reliable semi-automatic operation when installed in an appropriately prepared lower receiver.
