This is why I like this $50 pellet gun, so many things you can do with it and there's a ton of replacement/upgrade parts.
This is a video of what a guy (that I would call fanatic lol) did with his. Mine is a lot less elaborate and does the job I want it to do. I didn't drill anything or change valves and springs. I did ask a CNC machinist friend of mine to make me adapters for the tube i added to the barrel.

this is a pic of my crossman 2240
