Product Overview

Building an AR-15 from a forged lower receiver means sourcing the right small parts—and the Wilson Combat AR-15 Lower Receiver Small Parts Kit consolidates everything you need into one trusted package. Whether you're assembling your first rifle or completing a precision build, having all the internal components sourced from a manufacturer known for uncompromising quality takes the guesswork out of the job and ensures consistent performance on the range or in the field.

Wilson Combat parts are precision-manufactured to strict tolerances and tested for reliability under real-world use. This kit includes every spring, pin, selector, and detent required to complete a mil-spec lower receiver, so you won't find yourself halfway through assembly hunting for a missing component or settling for substandard alternatives. Each piece is engineered to function smoothly and hold up to repeated cycling and cleaning.

This is the kind of kit that appeals to meticulous builders who understand that a rifle is only as reliable as its smallest parts. Rather than cobbling together components from different sources—risking compatibility issues and inconsistent quality—you're getting a cohesive set designed and manufactured by a brand with decades of reputation in the AR platform.
