The AR-15 buffer retainer, 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 at the rear of the lower receiver adjacent both the receiver extension and buffer, the buffer retainer is a small but vital component that extends upward out of the lower receiver and is designed to retain both the buffer and the buffer spring within the receiver extension. The buffer retainer is locked into place via the receiver extension, which should be screwed into the receiver deep enough so that it rests atop the shoulder of the buffer retainer.
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. 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 your retainer breaks, your AR will be of limited use. If you are changing out a buffer and you shear off the tip of the retainer (I've done this), then you will not be able to take the upper off of the lower without having the buffer and spring pop out. Very annoying and potentially a real problem for weapon reliability. Have a spare in your kit. I keep one in the SOPMOD stock on my AR.
Not quite as smooth as some I've used but works fine. I'd buy another.
During a recent trip to range I saw a well made AR go down because of a missing buffer retainer. The shooter had installed a sling mount attached to the buffer tube and either lost it or it came loose during firing. Get one and have no worries.
These little retainers are a must have in your spares kit. An M4 -M16 will not work without it. I have seen it first hand. Very inexpensive but vital. Get one.
