The AR-15 barrel extension 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 at the receiver end of the barrel, the AR-15 barrel extension is a small steel extension that typically comes pre-installed on all AR-15 barrels, unless otherwise stated. For those with the necessary tooling and knowledge to install their own AR-15 barrel extension on a barrel, both pieces may be purchased separately. The AR-15 barrel extension is significant due to its integral feed ramps, which aid in the insertion of cartridges into the chamber, especially when done at high rates of speed such as in automatic firearms.

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 upper receiver. 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.
