Well I finally got around to making progress on my .22 LR pistol build. It was a whole bunch of fun spending hours mindlessly jigsawing through the steel plate but the hard work has been paying off. It’s still a little way off from being complete but it’s showing promise so far.
The plans are available for $12 from Serbu firearms if anyone is looking to make their own GB22. It isn’t too difficult and can be done with a jigsaw and hand files. I did use a manual mill for the barrel portion but it is possible to do with a hand drill and by welding it in instead of milling a groove and fastening with roll pins as I did.
