Mil-Spec Fit: Sized for small-pin AR-15 lowers to simplify maintenance and upgrades. Service-Friendly: A smart replacement during lower receiver rebuilds or when refreshing a high-round-count carbine. Ideal Use Cases General Purpose Builds: Solid, affordable component for new or refreshed rifles. Preventive Maintenance: Replace worn hammers to restore crisp function and ignition reliability.

Gunsmith Recommended: If you’re not experienced with fire-control components, consult a qualified armorer.
