JT ER2 pump pistol plans

i have one sitting in my basement in pieces trying to figure out what to do with it. I figure I will slip a freak insert in the barrel to give it a tighter bore match. heard all you have to do is heat it up with a hair dryer or heat gun and tap it in. then I want to run it constant air by getting a spyder style vertical air asa and putting a CP reg in the slot where the co2 cartridge goes so I can adjust the pressure for velocity. next time to decide if I want to run it on a remote like my tpx or try and rig up an asa on the bottom to run a 13 ci tank off it. I still have to fix my power tube as I tried to drill it out larger to allow more air flow and now it has a hole half way down the length. would rather have a metal one anyways. just looking for a fun pump to use in open play as I have grown tired of kicking butt with my works pump.
