QB78/Beeman Chief Stock

[Techie]

I have a custom stock on my QB78.  I don't like to shoot CO2 anymore now that I've discovered PCPs.  Does anyone know if a stock that is inletted for a QB78 will fit on a Beeman Chief?  If so I'd like to buy a Chief, put my custom stock on it, and throw out the QB78.  I have woodworking skills in case it's not a perfect fit, but I'm wondering if it's even possible.  Here are two pictures of my QB78 with the custom stock.  The QB78 is a .22 caliber, if that matters.

Edit:  I heard the trigger on the Umarex Gauntlet is a QB78 trigger.  Do you think it's possible to use my custom stock on a Gauntlet with some work?  I love my stock; just want to use it on PCP.

The gas tube on the QB78 is a different diameter than the air tube on the Chief.   QB78 is 0.875", Chief is 1.025".    With the difference in diameters, re-inletted may remove the QB78 barrel band notch.   The locations of the action hold down screws are in different locations.    And of course, the pressure gauge requires a hole bored in the QB78 stock.   Anything is doable, but not a direct drop-in.

That's exactly the kind of information I was looking for.  Thanks Craig!  Not what I wanted to hear, but now I know.

The Epox Badger which apparently is no longer sold by AirgunDepot because of supply issues.

Never heard of the Epox Badger before.  Thanks.  I looked it up.  .40 caliber, 2 shots per fill, can kill a deer, $800.  Amazing what they are doing with the QB78 platform.  Looks like it uses the original QB78 stock, so I assume the tube diameter is the same as a QB78.   Not what I'm looking for however.  The main advantage of airguns for me is that they have less power than a firearm.  If I want more power, I'll burn powder.   I guess I will give up on my idea and try to enjoy the gun in CO2.  I love wrapping my hands around this stock.

Well...There is another way out. Buy a longer tube with the proper valve anchor holes, have the valve drilled & tapped for the additional screws and use what you have for a dual fuel Bulk fill co2 or PCP.
