Not exactly, but close. I have a CM045A.
It's built like a tank inside and out. Good gears and well made GB shell. Standard V3 box so very easily upgradeable. RoF is fair but nothing too blistering. Accuracy is....alright. It's a pretty short barrel so don't expect miracles as standard. That said, a decent hop rubber and TBB should do well to sort that out.
Very well put together gun that is all metal apart from the foregrip and pistol grip (wood and plastic respectively on mine). For such a small gun it's pretty weighty. Most of the major components are pinned together so a set of punches would be a good investment if you plan on taking it apart much and don't want to wreck the pins. Gearbox removal is pretty simple. Nozzle is a clear hard plastic number which looks a bit fragile to me but time will tell.
Upgrades? Fill your boots. Standard V3 stuff all round. If you want to use a tracer you may have to do what I did and cut the very end of the inner barrel down. When you unscrew the flash hider the inner barrel extends by about an inch or so which covers the sensor in a tracer and stops it working. Sight mounting options ARE a little limited. The short length of the AKS74U means some soviet scope side mounts don't fit properly. There IS a little rail adaptor that can be fitted into the rear leaf sight but that does require drilling and tapping the top cover (plus you'll have to buy it from the US). To be fair, at the kind of ranges it works best at iron sights are fine or a red dot at most.
