JE Machine Tech PS-BTMS2 AR-15/M4 .223 Mil-Spec 8-Position Fluted Buffer Tube - Black

The JE Machine Tech PS-BTMS2 is an 8-position Mil-Spec fluted buffer tube machined from 6061-T6 aluminum with a Type III hard-coat anodized black finish. Designed for the AR-15/M4 platform (and compatible with AR-10 lowers), it accepts all standard Mil-Spec diameter buttstocks and serves as a drop-in upgrade or replacement for a wide range of carbine and rifle builds.

This buffer tube features ten recessed channels machined around the body for weight reduction, paired with three drain holes drilled through the tube to evacuate water in marine and wet-environment use. The combination of lightweight fluting and corrosion-resistant anodizing makes the PS-BTMS2 a practical upgrade for hunting rifles, duty carbines, and recreational builds alike.

As a true Mil-Spec diameter tube, the PS-BTMS2 is fully compatible with the vast majority of AR-15/M4 buttstocks on the market. Whether you're assembling a complete lower receiver or refreshing an existing rifle, this Made in USA buffer tube delivers the rugged foundation your stock needs.
