Spikes SLA500R 6-Position Mil-Spec Buffer Tube - Black Hardcoat Anodized

The Spikes SLA500R is a 6-position Mil-Spec buffer tube built as a direct-fit replacement for AR-15 carbines and rifles. Precision-machined from 7075-T6 aluminum and finished in a tough black hardcoat anodize, this tube delivers the strength, corrosion resistance, and tight tolerances that AR builders demand.

Six indexed positions let the shooter set the ideal length of pull for any stock configuration, with laser-engraved position markers for fast, repeatable adjustments. The tube interior is treated with dry film lube to ensure consistently smooth travel for the buffer and recoil spring assembly.

At 7.25" long with a 1.148" diameter and a weight of just 3.60 oz, the SLA500R drops into any standard AR-15 lower receiver and is an ideal replacement or upgrade for worn or missing factory tubes.
