A good buffer tube is important for reliable cycling and smooth shooting of your AR pistol. If you want a high-quality and dependable product from a name you can trust, get the Spike's Tactical Pistol Buffer Tube Assembly Kit.

The buffer tube itself is built to Mil-Spec standards and installs easily with the included dry film lube. The end plate features a quick detach sling swivel socket. The 17-4 stainless steel buffer spring will reliably bounce back every time without binding.

This kit also comes with the proprietary ST-T2 buffer. This buffer is accurately weighted to offer the best recoil absorption for the AR-15 platform. Spike's Tactical offers all of these parts in one convenient package!
