I’ve never handled an Impact or their barrels so I’m trying to understand why a different barrel sleeve is required when swapping calibers.
Obviously, each caliber will require its own liner, pellet probe and magazine but why should the barrel sleeve need to be changed?
The Impact’s receiver accepts all the calibers so that is a constant. Whatever fit or clearances between the barrel sleeve and the Impact’s frame also accommodates all calibers so that is not an issue. So as far as I can determine without drawings to refer to or an Impact to look at is that the fit of the liner to the sleeve is the only thing that needs to be addressed.
So, without knowing any better, my question is why can’t I just buy the largest (.30) barrel sleeve in the length that I want and machine a couple of bushings (outside diameter to suit the sleeve; inside diameter to suit the liner) to suit?
It seems to be a simple solution so I must be missing something. Can anybody shed some light on this?
Thanks
Hank
