EGW Evolved AR-15 Lower Receiver Spring Kit

Product Overview

The EGW Evolved AR-15 Lower Receiver Spring Kit includes the small lower receiver springs commonly needed during assembly, maintenance, repair, or replacement of lost or worn components.

Small springs are some of the easiest parts to lose during an AR-15 lower receiver build and can also become damaged, worn, or corroded over time. SKU 30020 gives you the essential lower receiver springs in one convenient kit without requiring the purchase of a complete lower parts kit.

The included springs are manufactured from stainless spring steel for consistent tension and corrosion resistance. This kit is a useful addition to a builder's bench, range bag, or spare-parts inventory for anyone who works on AR-15 pattern rifles.

Why Keep Spare AR-15 Lower Springs?

AR-15 lower receiver springs are small, inexpensive components, but losing or damaging one can stop an otherwise straightforward build or repair.

Keeping a dedicated lower receiver spring kit on hand gives builders and shooters replacement parts for routine maintenance, repairs, or components that disappear during disassembly.

This kit is especially useful for customers who already have their major lower receiver components and do not need to purchase another complete lower parts kit just to replace a spring.
