AR-15 Hammer
The United Defense AR-15 Hammer is a MIL-SPEC steel replacement hammer for any standard AR-15 fire control group. Machined to military dimensions and finished in corrosion-resistant black oxide, it drops directly into MIL-SPEC lowers using standard .154" hammer pins and common AR-15 hammer springs. The hardened steel body and precision-ground sear surface deliver a clean break and dependable ignition round after round. A smart pick for builders assembling a lower from parts, gunsmiths restoring a worn fire control group, or shooters keeping critical spares on hand.
