1-18, 1-20 and 1-22 are easy to find though.
Gm54-120, Do you know of anyone who has done this with an old mk 85? I have long desired a 45 caliber mk and have pretty much given up on finding one. I have quite a few mk 85s with the threaded barrels and would like to fit one with a 1" O.D. bull barrel .451 with either a 1 in 18 or 1 in 20 twist.
A couple of mine have the allen screw holding the barrel in place and then they were struck with a center punch to keep the screw from being removed. Do you just grind off a little metal with a dremel tool so you can take that screw out and then use some heat to unscrew the barrel.
Some of the other ones do not have the allen screw but I am 99 percent sure their barrel is screwed into the receiver as well. Do you just heat them up and unscrew it?
I'm just trying to gather information for now as this would be a winter project. Any help would be appreciated!
Thanks in advance,
