Evolve Weapons Systems AR-15 Lower Parts Kit with Trigger

The Evolve Weapons Systems AR-15 Lower Parts Kit pairs a single-stage PTFE trigger with name-brand small parts from Schmid Tool, Sprinco, and KNS Precision, plus a B5 Systems Type 22 P-Grip and Winter Style Trigger Guard. This version includes the grip and trigger guard in Black.

Features:

Sourcing small parts from established names like Schmid Tool, Sprinco, and KNS Precision — rather than generic Mil-Spec equivalents — is meant to give this kit an edge in feel and durability over a basic build kit.

Evolve Weapons Systems builds its AR-15 rifles and parts in McKinney, Texas, with an emphasis on quality materials and craftsmanship across every component, down to the small parts.
