Hey Bryan, I was just watching a vid for a device I got from vapingthings that is pretty much an aga-t but with a steel body, I'll post it here, as people may find handy hints in it, but he mentions the tight draw and suggests drilling it out with a 1/16th bit...and I don't know what that means exactly, being the mech wizard that I am, but there you go, 1/16th of an inch? Would that be mahoosive? Maybe not, don't ask me. All clear now, eh.
Yeah I find the same. Cleaned up the hole a little on the inside because it was a bit burry. Also stuck a paper clip through the hole as this was not cleaned out properly.
