The question made me more than interested so did some research.
AMT was sued out of business and they sat idle for several years, Galena Manufacturing took over and now manufacture the AMTs in Houston under the trademark of High Standard. Still supposed to be as accurate as before and have the same quality. High Standard has been around for a long time.
The last price I saw on the AMT Autoloader in .22WMR and the .17HMR is $695. This is pricey but the merchandise should be 1st class. I had a Ruger Single Six in .17 HMR, it was death on Wyoming prairie dogs. I had a Red Dot scope on it and it was a dandy. The AMT has always been A1.
Just my humble opinion. Probably more information than you really wanted but my interest and curiosity(nosiness) got in gear.
