Yeah, I read those sites before buying mine back in the day. Made it sound like one of the best rifles out there. Ended up buying it for $250, and kept it for maybe 5 months before selling it for $100.
Here's my review:
Fit and finish - Not too bad, looks like a decent rifle. Had some sharp edges that needed to be sanded, like the plastic trigger that could draw blood if you weren't careful.
Feel - It's pretty bloody heavy, at over 8 lbs before scope. Needs to be that heavy when it's running full power to tame the recoil, but in non-PAL, it was a waste. Shouldered OK, but not great. Not very well balanced, I felt it was too front heavy.
Trigger - Bloody awful. It was about a 5 lb pull, and you never knew when it was going to fire. It was mushy, and with no discernible second stage, it was a complete guess as to when it would fire. The pull was obnoxiously long, as well. I bought and installed the GTX trigger which improved it, but it went from useless to somewhat usable.
Accuracy - I just couldn't get the thing to group well. I fired my 500 break-in shots after cleaning the barrel, and it was still inconsistent. Whether using the artillery hold or off the bags, I was lucky to get a 1" group at 10 yards. A guy I know who owns one that tuned it to smooth it out, and has fired thousands of shots is getting about 3" groups at 50 yards. All the talks of this being an MOA rifle are nonsense. I've seen plenty of people shoot these things, but never seen results anywhere close to that.
Scope - The included scope was probably the best part. I actually kept it, and it's mounted on my Remington Airmaster. Holds zero well, and has turned that cheap shooter into something I would consider useful.
As for trouble zeroing it in, I could see that. Some people suggest Loc-Tite on the stock screws, others suggest differently. I had no luck either way. It's fine as a plinker, but there are much better rifles for the money. If you are hoping for real accuracy, I suggest moving on.
