The AR-15 firing pin is, as are all of our house brand spare and replacement parts for the AR-15 platform, 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 bolt carrier group, the AR-15 firing pin is a steel pin that facilitates the firing sequence, as it is responsible for transferring energy from the hammer to the primer of a cartridge. After the firing sequence is initiated by a trigger pull, the hammer strikes the firing pin, which will jolt forward and in turn strike the primer. This serves to ignite the propellant gases within a cartridge and send a bullet downrange. It is secured within the bolt carrier group via the firing pin retaining 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. If you have any need or desire for spare or replacement parts, now would be a good time to take advantage of this offering.

I bought this firing pin as a back up. I couldn't find a better price online and the low prices at keep me coming back for gear. It actually looks like it's a little better quality than the one that came with my rifle. I'm glad i have it.

This is a must for your AR 15 spare parts kit. If you are having a lot of misfires, check your firing pin before knocking your ammo. Like any other moving part that is under a lot of force, firing pins do wear out. Pick up some spares from KS while they are in stock and at a decent price.
