I was lucky enough to get one of the laminate stock versions, the last yellow and black one from EDgun West. It's an R5M standard in .25. I wanted to have the short overall length bullpup for easy/quick handling in the EDgun padded green soft bag storage bag and in the field hunting.
The shorter length makes it a bit more wobbly when shooting offhand, requiring good technique or an object to brace against. Brian at EDgun West can install a short picatinny rail on the forearm very inexpensively to which you can attach a bipod that adds mass to the frame to smooth out some of the wobble and of course for shooting from braced/ rested positions.
It's a hunting trigger as already thoroughly described, I made several adjustments until I was happy enough with it. Have not tried polishing the sear engagement surfaces - that may come sometime in the future. I have been satisfied with it as it is.
The smaller reservoir of the standard is relatively easy to top off with a Hill MK IV hand pump, which was important since I do not want or own an electric compressor at this point. My companion Leshiy (.22, 350mm barrel-awesome with JSB 14.3 BTW) is even quicker to fill with a hand pump.
The stock comes off quickly with 2 screws for HST adjustment. The hammer spring adjustment screw is detented, allowing you to count clicks for reliable power changes. Be sure to keep notes on how yours is set or you can use a chronograph for repeat adjustments. The rear bolt block removes easily with one extra screw to allow barrel cleaning and polishing. I had to do some careful filing and fitting of some folded metal on the bushing of the rear bolt block to allow it to slide on and off the breech without tapping. The moderator unscrews from the muzzle end very quickly and conveniently for the same purposes.
I had a little trouble with the electronic gauge at first. The battery had run down and I had to replace that, then reset it a couple of times after installing a new battery. I don't find the advanced electronic functions helpful at all, I just tap it every now and then to read the pressure in BARS.
I mounted a vortex diamondback 6 to 24 by 50 ffp scope with moa reticle and adjustments. Very nice setup.
Some other nice features include slots for storing 3 magazines inside the scope rail and the lugged stock which makes a nice upside down carry handle.
