I'm a big fan of Curtis' builds. Incrediby quiet, great quality, and I enjoy talking to Curtis during the process. I was out there recently to pick up an interesting gun, another builder that licensed Curtis design and built an S+H like gun that Curtis never built, a Camp Carbine .45, intergrally suppressed, from John's Guns in Texas. But that isn't the story, I always ask Curtis what he is working on, I like to try to do a transfer a year if I can, and I am due. He showed me his latest build, an AR based 300 blackout, with his suppressor technology adapted to it, really cool, and of course really quiet, so I've got another approval in the process... I'll add a pics in a bit.
