Spike's Lpk Small Parts 308 No Fcg

The Spike's Tactical Lower Parts Kit Small for .308 (without fire control group) is a precision-engineered component set designed to complete AR-platform .308 lower receivers when used with a separate trigger group. This kit consolidates essential small parts that are often scattered across multiple vendors, saving operators and builders time during lower assembly while maintaining Spike's reputation for domestic manufacturing and quality control.

The kit includes a safety selector with detent and spring, magazine catch assembly with spring and billet magazine button, buffer retainer spring and plunger, and a pro grip. Each component is manufactured to tight tolerances—critical for reliable cycling and ergonomic function in larger calibers where spring forces and tolerance stack-up directly impact reliability. The billet magazine button is more robust than standard stamped alternatives and resists wear during extended use. All parts are made in the USA, ensuring consistent quality and traceability without foreign supply chain variables.

This kit is purpose-built for shooters completing .308 lower builds using Spike's Tactical Jack10 or Livewire platform sets. It eliminates the guesswork of sourcing compatible small parts individually. To complete a functional lower, users will still need to source a buffer tube assembly, stock, and trigger group separately—allowing customization of those components based on mission profile, whether that's precision rifle work, competition shooting, or duty use. Weighing just 0.25 lbs, it's a lightweight addition that doesn't compromise on material quality or durability.
