So here's my story with them.
When I first got mine, it was second-hand. The owner didn't want it anymore and had barely even used it out of the box. Unfortunately they nicked the rear sight off of it so I couldn't ever use it without a scope unless I wanna try my hand at aligning targets via the barrel length.
The Nikko Stirling 4x32 was of my own purchase as well, the full rifle was $240. Not a bad price actually, in fact one of the better cheap .22 rifles on the market.
Now as for the rifle itself, the reason you're getting a seemingly direct copy of a Brno Model 1 so cheaply is because that due to the manufacturing capabilities of Norinco, they're not the greatest in terms of fine machining. In fact, the entire length of the raceways, the shape of the bolt and especially the camming surfaces are pretty rough. There is a youtube tutorial that goes into the full process of cleaning up a CZ which essentially is the same design as the Norinco. Spend some time over here:

Also if you're ordering this new/semi new, you're gonna want to disassembly everything and soak it in a heavy degreaser/petrol. The mysterious Chinese packing oil contaminates these things like the plague and is the reason they get complaints on their tightness. You're also going to need to free float the barrel if you're sticking with the crummy plastic stock, or alternatively you can order a stock from Hatchers Rifle Stocks:
Also, the trigger is actually fairly workable too, here's a guide on that. I've set mine to roughly 2.5 pound and cleaned up the sear/trigger relation surfaces up with a fine buffing wheel, and autosol on a small earbud.

. Nowaday's I'm shooting ragged holes. Here's a list of all the 22's i've used in it so far, from best, to crappiest.
Gecko Target Box 40grn
SK (Especially red-box match ammo)) 40grn
Eley subsonic 40grn (Best choice hunting round)
Eley supersonic 40grn
Remington Subsonic 40grn
CCI Mini Mag 38grn
Winchester Super Speed 40 grn
CCI Stingers 32grn
Winchester Powerpoint 42grn
CCI Quiet 40Grn
Federal 40grn
Winchester Z's 28grn (Absolute crap, dont even bother, shoots minute of Kim-Jun)
On the hunting side of things, it's a great lightweight rifle and when put together with a sling, it'll go with you anywhere. I've taken all kinds of things with it from rats, to bunnies, to hares, to wallabies, even the occasional pest bird. The thing definitely pays itself very quickly! Also managed to knock the cap off a coke bottle placed out at 190M, after a few spotters here and there. They're rugged, reliable and honestly I've never had a single misfire that wasnt due to dodgy ammo. Only had one magazine hang-up as well which was my own stupid fault (slammed the rim in and under the follower trying to load it in a hurry in the dark.)
Its worth the 2 greenies and a yellow mate, believe me. Happy hunting.
