BACKGROUND 
       [0001]    This disclosure relates generally to a receiver extension casing method of use. One example of a receiver extension and/or receiver extension accessory can be found in US Patent Application Number 2012/0137562. However, none of the known inventions and patents, taken either singularly or in combination, is seen to describe the instant disclosure as claimed. Accordingly, an improved receiver extension casing method of use would be advantageous.

         [0004]    Said second gun reinforcement comprises a one or more casings between a buttstock and a castle nut of a gun. Said one or more casings slide around a buffer tube of said gun. Said one or more casings cover a portion of said buffer tube. Said one or more casings have a first end and second end. 
         [0005]    Said gun reinforcement method comprising: removing a buttstock from a buffer tube of a gun, sliding a one or more casings around said buffer tube of said gun, and attaching said buttstock on said buffer tube of said gun. Said one or more casings slide around a buffer tube of said gun. Said one or more casings cover a portion of said buffer tube. Said one or more casings have a first end and second end.
