TacFire LPK02USAB Lower Parts Kit with PGAR-B grip Pistol

The TacFire LPK02USAB Lower Parts Kit with PGAR-B Black Grip is a complete, USA-made component set designed for AR-15 lower receiver assembly. This lower parts kit provides all essential springs, pins, levers, and controls required to build a fully functional AR-15 fire control group and bolt catch assembly, making it a practical choice for builders, gunsmiths, and operators standardizing on domestic components.

The kit includes a TacFire PGAR-B-USA pistol grip in black, trigger group components (trigger, trigger pin, trigger spring), hammer assembly (hammer, hammer spring, hammer pin), bolt catch system (bolt catch, bolt catch spring, bolt catch roll pin, bolt catch buffer), magazine catch assembly (magazine catch, magazine catch button, magazine catch spring), disconnector spring, take-down system (take-down pin, take-down detent), buffer retainer components (buffer retainer pin, buffer retainer spring), and trigger guard. The complete component count ensures minimal additional sourcing when assembling a lower receiver, reducing complexity and compatibility concerns.

This lower parts kit serves gunsmiths assembling multiple rifles, shooters performing their own lower receiver builds, military and law enforcement armorers restocking components, and precision rifle builders who prefer sourcing complete kits to individual parts. The USA manufacturing aligns with buyers prioritizing domestic supply chains and reducing lead times on critical components. At 0.6 lbs and compact dimensions, the kit ships easily and stores efficiently in a parts drawer or armorer's kit.

Lower parts kits remain essential for AR-15 platform builders because they bundle the fire control group, safety controls, and bolt manipulation components that define rifle function. By combining these elements into a single package with matched tolerances, a quality LPK reduces assembly errors and ensures proper part interaction—critical factors in carbine reliability for duty or competition use. The TacFire brand positions this kit as a cost-effective, domestically sourced alternative for shooters who prioritize component transparency and domestic sourcing over premium machining or proprietary features.
