The AR-15 hammer, as are all of our house brand spare and replacement parts for the AR-15 platform, is a brand new part produced in a state-of-the-art manufacturing facility that holds several foreign military contracts. As such, all parts are compatible with and interchangeable in any MIL-SPEC AR-15.

Located within the lower receiver adjacent the trigger and disconnector, the AR-15 hammer is a vital component to the operation of the rifle as it plays a crucial role in the firing sequence. After the firing sequence is initiated with a trigger pull, the hammer is released so that it may strike the firing pin, which in turn strikes the cartridge primer. It is secured inside the lower receiver via the hammer pin.

Spare and replacement parts are an important consideration when it comes to firearms. Like any machine, firearms rely on a series of parts to function properly – especially those components that impact the firing sequence. In general, if a part breaks or fails, a repair or replacement becomes immediately necessary – not only to keep a firearm functioning properly but also to ensure the safety of yourself and those around you.

It is also important to consider availability when discussing spare and replacement parts. At this time, is seeking to provide our customers with a wide selection of spare and replacement parts for the AR-15 platform. Several brand new parts from the house brand are now readily available on our website at an affordable price.
