LBE Unlimited AR-15 Hammer Spring 20-Pack Silver Stainless Steel

The LBE Unlimited ARHS20PK is a bulk 20-pack of replacement hammer springs for the AR-15 lower parts kit. Each spring is cut from 17-7 stainless steel and finished in a natural silver tone, giving them the corrosion resistance and consistent tension that gunsmiths and home builders expect from a mil-spec hammer spring.

Engineered to meet or exceed military specifications, these hammer springs deliver reliable ignition and consistent trigger-group performance across duty, range, and build-up applications. Whether you are running a full parts refresh, assembling a new lower, or simply stocking the bench for future repairs, the 20-pack format keeps your AR-15 build moving without repeated reorders.

LBE Unlimited hammer springs are Made in the USA and drop into any standard AR-15 lower that uses a mil-spec hammer, making this pack a straightforward upgrade or service item for armorers, gunsmiths, and recreational builders alike.
