The Sons of Liberty Gun Works Intermediate 10-Position Maritime Buffer Tube Kit is a comprehensive, corrosion-resistant buffer system upgrade that provides enhanced adjustability, reliable cycling performance, and maritime-grade durability in a single, complete package. The 10-position buffer tube offers significantly more length of pull adjustment range than standard 6-position mil-spec tubes, accommodating a wider variety of shooter body types, gear configurations, and shooting positions without compromise, and the maritime design incorporates drain holes that prevent water accumulation in wet and submerged operating environments. The 5.6 ounce buffer and power spring are matched to deliver reliable cycling performance across a wide range of AR-15 configurations and ammunition types, and the QD end plate provides immediate quick-detach sling attachment capability without the need for additional adapters or hardware. The castle nut completes the kit with everything needed for a clean, tool-assisted installation, making this a comprehensive and purpose-built buffer system upgrade for AR-15 owners and builders who demand enhanced adjustability, maritime corrosion resistance, and reliable cycling performance from a trusted American manufacturer.
