VKTR Industries AR-10/AR-15 Hammer Spring 10-Pack

The VKTR Industries WLA-PAC-1004-10 is a 10-pack of Mil-Spec replacement hammer springs built for AR-10 and AR-15 lower assemblies. Produced by VKTR Industries (the manufacturer behind the White Label Armory line), these standard-power hammer springs are intended for new builds, repair work, and routine servicing of AR-pattern rifles.

Each spring is corrosion resistant with a silver finish, delivering the consistent trigger return action expected from a true Mil-Spec component. The hammer spring sits at the heart of the fire control group, so a fresh, properly rated spring is essential for reliable ignition, clean trigger break, and reset on both AR-10 and AR-15 platforms.

The 10-pack format is a smart choice for armorers, gunsmiths, and home builders working through multiple lower assemblies, providing enough springs to handle routine rebuilds, to replace worn components during servicing, or to keep on the bench as essential spares. Suitable for builds and repairs, these hammer springs drop directly into any standard AR-10 or AR-15 fire control group.
