I have a J68. It's the next generation version of the J67. The trigger on it is fabulous, pulling at about 2.5 pounds. I really like the design for the most part. It's simple and elegant. Though the need to use tools to separate the halves is a drawback. (The J67 is better in this regard.) I had an idea about how to make them easy to separate which they really liked. Hopefully they'll be able to make it work.
It is a bit on the heavy side, but as a bullpup that's also a range toy, that's not at all a problem. The balance is really good when holding it in a firing position. Unfortunately I've had some problems with the hammer and feeding problems, so I haven't been able to get a lot of trigger time with it. It's at Jard right now for repairs. They are really great guys to talk to and eager to help.
