Spike's Lpk Small Parts 308 No Fcg

The Spike's Lpk Small Parts 308 No Fcg is a precision-engineered component set designed for completing AR-platform .308 lower receivers when paired with a separate trigger group. This kit consolidates essential small parts that are often sourced from multiple vendors, streamlining the assembly process for builders and operators alike.

The kit includes a safety selector with detent and spring, a magazine catch assembly with spring and a billet magazine button, and a buffer retainer spring and plunger. Each component is manufactured to tight tolerances, which is critical for reliable cycling and ergonomic function in larger calibers where spring forces and tolerance stack-up directly impact reliability.

This kit is ideal 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, while allowing users to customize their buffer tube assembly, stock, and trigger group based on their specific mission profiles.
