EGW Evolved AR-15 Lower Parts Kit | Machined Lower Receiver Components
Quick Check: Premium builder-focused lower parts kit for AR-15-pattern receivers.
Platform: AR-15
Kit Type: Builder-focused lower receiver parts kit
Major Components: CNC-machined from solid steel
Springs: Stainless spring steel
Important: Fire control group, safety selector, pistol grip and trigger guard are not included.
The EGW Evolved AR-15 Lower Parts Kit provides a premium foundation for a new lower receiver build, repair or component upgrade. Instead of treating the smallest receiver parts as an afterthought, EGW developed the Evolved line around precision machining, durable materials and corrosion-resistant finishes.
Major components such as the bolt catch, magazine catch, magazine catch button, pivot pin and takedown pin are CNC-machined from solid steel instead of MIM. Applicable steel parts receive a QPQ finish for surface hardness, lubricity and corrosion resistance.
The included lower receiver springs are manufactured from stainless spring steel to help resist corrosion and maintain dependable spring tension. Every component in the kit is proudly made in the USA.
Important Kit Configuration
This is a builder-focused AR-15 lower parts kit. It contains the exact core components identified in the included-parts list below. It does not contain every component required to complete an entire lower receiver.
The fire control group, safety selector, trigger guard and pistol grip are intentionally excluded. This allows the builder to select the trigger, safety and ergonomic components that best match the intended build.
Platform compatibility: This kit is designed for AR-15-pattern lower receivers. It is not designed for AR-10, LR-308 or AR-9 lower receivers.
Minor fitment may be required. Receiver and aftermarket-component tolerances can vary. All components should be inspected for proper fit and function during installation.
