Just had a chance to put a few rounds downrange while doing a tactical course on Saturday.
With the irons, which were right on at about 25 yards, it was shooting bugholes with the American Eagle 55Gr.
Recoil, compared to less than punishing 7.62X39, was pleasantly
light.
It comes with the side receiver rail required for Soviet style scope mounts, but aftermarket top rails are available to fit the VZ/CZ family of rifles.
The trigger was pretty good, but the magazines, which are plastic, seem like they might be less durable than the regular 'indestructible' ones that come with the 7.62X39 guns.
Overall, I was favorably impressed, and would recommend them to someone thinking about a high quality, likely reliable, non-restricted 'black rifle' in .223, which fits nicely into the price niche between a Mini-14( don't get me started!), and the now obsolete AR 180-B.
I would budget (?dollars) for the forthcoming 'kit' that would allow the use of regular AR style magazines.
