Tacfire Ar-10 Lower Parts Kit - Black

The Tacfire AR-10 lower parts kit in black gives you a complete set of internal components to assemble a functioning AR-10 lower receiver. If you're building an AR-10 from a stripped lower or refreshing the internals on an existing platform, this kit handles the trigger group, hammer, bolt catch, magazine catch, selector, and all the springs, pins, and detents required for a working rifle. It's a straightforward way to avoid shopping for parts individually.

The kit includes a Tacfire PGAR-B pistol grip in black, angled trigger guard, and trigger and hammer components manufactured in the USA. Everything you need comes in one package—no guessing about compatibility or compatibility gaps between different manufacturers' parts. This is practical for builders who want to get their AR-10 lower functional without the assembly line of single-component orders.

Tacfire focuses on delivering solid, no-nonsense components at a working price point. This lower parts kit reflects that approach: it's built to function, not to be flashy. Whether you're assembling your first AR-10, setting up a second rifle, or keeping a spare lower ready, a complete parts kit eliminates the friction of sourcing each piece separately and ensures nothing gets overlooked.
