The AR-15 bolt catch spring, 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 spring is a component of the bolt catch assembly, which also includes the bolt catch, the bolt catch roll pin and the bolt catch plunger. Located within a small recessed hole in the left side of the lower receiver, sandwiched between the bolt catch plunger and the lower receiver, the bolt catch spring is a small spring that facilitates proper functioning of the bolt catch. It is essentially secured by being "trapped" between the two aforementioned components.  

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.
