We carry a huge variety of AR-15, AR-10 and AR-pistol buffers, tubes and buffer tube kits. Each build will require a different setup and buffer assembly to help provide enough force to push your bolt carrier group forward after firing in order to chamber the next round. If you are interested in a buffer tube replacement for your AR15, we have a wide range of options to choose from including the highest-quality carbine buffer tubes and buffer tubes for collapsible stocks.

We have options for complete buffer tube kits or buffer tubes alone, with free shipping on select items. We have mil-spec mounting kits that have everything you need to mount your replacement buffer tubes with ease. We have buffer tubes for both rifles and pistols from the most respected brands in the industry including Spike’s Tactical, CMMG, WMD, BCM and more. Depending on the weight your rifle or pistol requires, we have H-1 buffer tubes as well as H2 buffers and H3 buffer tubes to accommodate those in need of the extra weight.
