anyone wanna make me a shroud? and or endcap for my tube?

on the cheap
nothing fancy
ill be installing it on my Mountainair 2250xt with the 24 in bbl when it gets here
actually what i want is an adapter and end cap for my tube
the one end needs to have a .25 cal opening im going with .25 so i know there is no clipping with my .22
the other needs to fit inside my tube and step up to match the OD of mine and have enough extra sticking out to put a grub screw
anyone up for the task?
dimentions are as follows
odd of bbl .436″
inside dia of my tube .820″
Outside diameter of my tube 1.060″

i have some ideas i want too try for baffles so all im looking for is the befor mentioned endcap for the tube and the piece to hold it onto the bbl
