Looking at the photos I am convinced that whoever makes this also makes the DAR. This is not a bad thing I love my DAR II. The magazines are the best I have ever used. Looks like a DAR with a better trigger and quality control.
Rich I'm sure the mags on the JTS are much better than the DAR, you will be able to pull the mag out after a shot and top it off which aren't as easy to do in the DAR. They're a complete and totally different gun. JTS will put the DAR to shame in my opinion, even my Xisico Sentry's put my DAR to shame, I waited over a year for a bad part that was on my DAR when I bought it to FINALLY get it, I had pretty much wrote that DAR2 off, it is sitting in the box and has been since I bought it, I'd much rather grab another gun.
My mistake David I was thinking of the Avenger probably but since I put that part in my DAR2 I haven't really touched it, haven't even put a scope on it yet but I will probably soon. If the DAR's are working and holding air good they are a great shooting gun but I got so disgruntled with them that I'd definitely never buy another one.
