The AR-15 buffer retainer spring, as are all of our Keepshooting.com 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 in a recessed hole at the rear of the lower receiver beneath the buffer retainer, the buffer retainer spring is a small spring that exerts its tension upward out of the lower receiver and is designed to force the buffer retainer to hold its place. This allows the buffer retainer to do its part by retaining both the buffer and the buffer spring within the receiver extension, which should be screwed deep enough into the receiver so that the buffer spring does not force the buffer retainer out of position.
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, Keepshooting.com 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 Keepshooting.com house brand are now readily available on our website at an affordable price.
