The AR-15 bolt catch, 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.

The AR-15 bolt catch is a component of the bolt catch assembly, which also includes the bolt catch roll pin, the bolt catch plunger and the bolt catch spring. Located on the left side of the lower receiver atop the magazine catch, the bolt catch is a small but vital component that extends into the lower receiver and is designed to lock the bolt carrier group to the rear of the receiver upon discharging the final cartridge in a magazine. Upon inserting a new, loaded magazine into the magazine well and depressing the bolt catch, the bolt carrier group will be released, locked into battery and ready for fire. It is secured within the two ears found on the left side of the lower receiver via the bolt catch roll 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 make up the fire controls. 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.

If you've ever done much work on your AR-15, you know that you will eventually need spare parts. The bolt catch is a small and rather fragile piece. If you're really rough with your AR (perhaps dragging it through a gravel lot to prove the durability of the handguard), you might end up damaging the bolt catch. So if you're as abusive to your weapons as I am, you should probably have one of these on hand, just in case.
