There are some incredible gunsmiths out there when it comes to the Kalash. Jim Fuller is one, obviously (someday I’ll get to take the Rifle Dynamics AK Builder Class). Owen Martin appears to be another (I’m still aggravated I couldn’t attend the Shoot Heard Around the World).
There are others of course, but I’ve never before seen or heard of anyone or anything quite like Jimmy DiResta working an AK this way.
I made a Claymore Mine out of popsicle sticks once.
