The Spike's Tactical SLA500R-K is a mil-spec rifle buffer tube assembly built for AR-15 and AR-10 platform rifles that demand reliable, repeatable performance. Whether you're setting up a new build, replacing a worn tube, or upgrading to a proven mil-spec standard, this high-strength aluminum assembly gives you the solid foundation that matters when accuracy and consistency are on the line. It's the kind of component that works quietly in the background—until you need it to, and then it just does its job.

This complete assembly kit includes everything you need for installation: the mil-spec buffer tube itself, a heavy-duty ST-T2 buffer, the carbine-length buffer spring, end plate, and castle nut. That means no extra trips to source parts or hunt down compatibility specs. Mil-spec dimensions ensure drop-in fit with standard AR receivers and stocks across the industry, so swapping uppers or moving components between builds stays straightforward.

High-strength aluminum construction keeps weight down while maintaining the rigidity needed for consistent lockup and repeatable cheek position—especially important if you're running optics or running splits at distance. The black finish resists corrosion and blends seamlessly with most AR builds. Whether you're running a precision rifle, a duty carbine, or something in between, a mil-spec buffer tube assembly is foundational—get the one that works and move on to the shooting.
