The machining quality does fall in the perfect category(not that its a term we use much in this metal cutting biz), they do a very nice job and definitely got a good process down.
I've never had any extraction issue yet nor heard of it being a problem with them. Must be some pretty hot loads if its sticking eh.
What would you say is the perfect action?(when it comes to the higher end custom stuff) everything else I looked at so far had other features that personally I find to be a bigger concern(or less desirable), not that they aren't very nice as well and certainly get the job done. I just think barnard did a nice solid yet simple design and I'm likely getting another for the next rifle but I'm open to suggestions, always fun to test out other stuff.
