The SOLGW Maritime Buffer Tube Kit (Sons of Liberty Gun Works part no. SOLGW-INT10POS-KIT) is a complete buffer tube assembly built by Sons of Liberty Gun Works for AR-15 builders who want a maritime-rated buffer system. Sons of Liberty Gun Works has built its name on tight quality control across mil-spec small parts, and this kit follows the same standard, bundling the receiver extension, buffer, spring, and hardware needed to complete a rifle’s buttstock mounting system. A maritime-spec buffer tube kit is built to resist corrosion and function reliably after exposure to water, making it a natural fit for duty, competition, or any build that might see harsh weather. It fits mil-spec lower receivers and installs alongside your stock of choice.
