Mr. Phili;
Welcome to the Campfire from the south Okanagan.
I've played with several Cooey 64B's over the years and they are as grouseman noted, very Canadian which is cool.
There was a transition, perhaps between a 64 and a 64B where they changed the magazine. The older ones would not always feed that well.
They like to be clean and if possible you should either strip it yourself and give it a thorough scrubbing or get it done and watch.
It really isn't hard to accomplish once you see it done and they do indeed seem to run better with a clean and lightly lubed bolt.
The triggers are certainly what they are on any I've played with
That doesn't mean they aren't fun to shoot and accurate enough to, as grouseman said - account for bushels of gophers.
Hopefully that was of some use to you. Good luck with your 64B.
Regards,
Dwayne
