Spikes 6-position buffer tube
Reviewed on April 13, 2026Verified with Build

Spikes Tactical milspec buffer tube has the standard 6 positions and the rear QD socket. Threads to a milspec castle nut without issue. Anodizing is the matte black expected. Integrated QD socket means no separate end plate needed for a one point sling.
