I've got one, I wanted to do a youtube review but that never happened, but here's my comments:
Shoots pretty darn good, I think I paid less the $350 when i bought it. Fully adjustable trigger!
Now the bad, the bolt was the exact opposite of smooth, someone once used the analogy of "moving a boat paddle through a barrel full of gravel" that comes to mind. It literally was rough, and machine marks and scratches on the bolt after cycling for a while.
My remedy for this was to polish some surfaces that seemed rough with emery cloth, coat the bolt and action with valve grinding compound, I didn't just cycle the action, I basically welded a socket onto a sawzall blade, ran black tape over the bolt knob, inserted the bolt knob snuggly into the socket, and then cycled the action back and forth then the bolt up and down with the sawzall to pick up the pace for a while, probably equivalent to cycling the bolt every evening for an hour and a half for three weeks. It got a little better, then I cleaned it out, and coated some of the action surfaces and bolt with a graphite paint, and then oiled it, it cycles "reasonably" well now. I wouldn't call it great, nowhere close to my tikka.
I bedded it with JB weld before I even took it out, the inletting was rough, may not have changed anything, but the wood fitment and clearances are nothing to be proud of.
The magazine was tight in the stock, the first round would feed fine, as it is single stack, the magazine would be slightly pinched just tight enough to prevent the next round from popping up to the feed path, I had a "fail to fire" on the second round, and soon fixed it.
One of the screws for the rear open sight was too long, it bottomed out, and left the mount wobbly, oh yeah I forgot, the rear mount is on a section of barrel near the action that is tapered, the rear mount is basically just radius'ed for one size, not for a changing radius, like the section of barrel it is mounted on. After grinding down the screw though it is tightly in place.
The front sling pin is too close in to the stock, it fits fine for a sling, but to get a bipod on it the bipod presses against the wood marking it up.
I wish it was an AR (or rather LAR-15) style mag feed path, with larger capacity and options.
Having said all that bad stuff about it, it still shoots pretty good, once sighted in on the bench it was ringing the 300 yard gong every shot with gusty wind when I had it out last summer, and that was with open sights, as the scope I had put on it was junk out of the box (barska).
It may be a candidate for another AICS airsoft stock project, but I actually bought it for a relative to hunt with (first nations and she just wanted to use a .22 for deer, doesn't like recoil, but morally I was against using a .22, though it seems to be popular with them in many places, they just take close range head shots from what I hear).
