Pws Enhncd Bffr Tube Mil Spec Gen 2

The Primary Weapons Systems Enhanced Buffer Tube Mil Spec Gen 2 is a precision AR-15 buffer tube engineered for reliable cycling performance across diverse operational environments. Extruded from 7075-T6 aluminum, this mil-spec diameter tube combines reduced weight with structural integrity, making it an effective choice for shooters building or upgrading AR platform rifles who demand enhanced carrier support and extended length-of-pull adjustability.

The Gen 2 design features six position adjustment options for tailoring stock fit to different shooter profiles and tactical equipment loadouts. An anti-tilt lip ensures consistent bolt carrier travel and smoother operational cycling. Longitudinal flutes reduce weight without sacrificing durability, while integrated drainage ports address corrosion concerns in wet or saltwater-adjacent environments—a critical consideration for maritime operations and humid climates. The included ratchet lock castle nut and endplate provide secure, tool-free assembly and positive lock-up.

This buffer tube suits law enforcement patrol rifles, military training builds, civilian sport shooting platforms, and any AR-15 configuration where adjustable length-of-pull and marine-grade corrosion resistance matter. The mil-spec diameter ensures compatibility with standard AR furniture and sling attachment systems, including quick-detach mounts. Operators who have transitioned between platforms or who run modular rifle systems benefit from the expanded adjustment range, which accommodates variable body armor profiles and equipment configurations.

The 7075 aluminum core and precision extrusion maintain dimensional tolerances that prevent rattle and binding—essential for repeatable shot placement and reliable recoil impulse management. At 0.44 lbs, this tube preserves carbine balance while offering the structural attributes of heavier alternatives, making it practical for extended patrol or training cycles where shooter fatigue is a performance factor.
