  • Publication number: 20090255161
    Abstract: The invention is an improved load bearing arrangement for use with firearms. The system comprises a cylindrical body with a sealing cap, mounting structure on the body including a plurality of mounting tabs and a “T” rail with matching structure on the stock. The mounting tabs are only partially fastened on the body so as to form hooks which will secure the body from behind the structure on the stock. The “T” rail interfaces with a corresponding notch on the rear of the stock and is secured with the stock's butt pad. A water-tight cap is also provided, which is also capable of removal and replacement without removing the remaining structure from the stock.

  • Patent number: 7152355
    Abstract: The present invention is a modular stock system for rifles.

A stock module then mounts on the replacement buffer tube. The stock module is interchangeable depending on the user's needs. Various configurations of the stock module are discussed, including adjustable stocks, fixed stocks, and specialized stocks. The stock module may be made even further modular by the addition of rail system.
