Crosman 180 and 400 bulk fill?
JayDee24ca:
I have nice examples of both these guns, and have been wondering if it is possible to bulk fill them. If so, what would I be required to do? I do not want a tethered gun, but a true bulk fill. Has anyone here done this to these rifles?
OTmachine:
You could just add a drop block and a HPA tank regulated @ 850 psi. Or buy or make a new pressure tube end cap to accommodate bulk fill CO2.

TerryM:
I converted a 180 to bulk fill using a tube extension from Mac1 and a fill cap from Brian and Associates. B&A is no longer around, I don't know about Mac1. The extension is 8”. Gun holds about 50 grams of CO2. The extra barrel band is one made for a QB. Had an old Weaver J4 on when this picture was taken, now have a Nikon 4x32 on it.
OTmachine:
Nice rifle! Flying Dragon had done up a Xisico XS60C like that for HPA.
JayDee24ca:
I guess what I really want to know is if there is any valve modification needed. I have a couple of bulk fill adapters I got from Bakers a while ago that I was planning to use on my Disco and maybe on a Cr150. On the rifle that has had a tube extension added to it, how is the tube attached? Was it welded in, or threaded?
