Tacfire Ssrk308Lpk16N Rifle Kit 308 Win Black

The TacFire SSRK308LPK16N is a 308 Win lower parts kit designed for builders and gunsmiths assembling an AR-platform rifle in .308 Winchester. If you're putting together a precision rifle or tactical build from a stripped lower receiver, this kit includes the internal components you need to get your action running. TacFire parts kits are a no-frills choice for shooters who prioritize function and value over brand prestige—ideal for hunters, competition shooters, and range enthusiasts building on a budget.

Lower parts kits are the often-overlooked foundation of any AR build. While upper receivers and barrels get the attention, the lower is where reliability lives—it houses your trigger group, safety selector, bolt catch, and all the springs and detents that make the rifle go bang. This kit is caliber-specific for .308 Winchester, so you're getting components matched to that cartridge's demands rather than a generic universal kit.

Whether you're a first-time builder or a seasoned gunsmith, having quality lower parts on hand speeds up assembly and eliminates the headache of sourcing individual components. TacFire keeps things straightforward: solid performance, competitive value, and no marketing fluff. Pair this with a stripped lower receiver and an upper assembly to complete your 308 rifle.
