Does anyone have any information/has anybody used this scope (or any of its 'relatives')?

I purchased on a week or so ago (for 50 bucks, I thought I'd take the chance...CDNN is 'good folks' in my book, never steered me wrong or failed to accept a returned product!) to try on top of my AR for use in Tactical 3-Gun meets.  Certainly, it's no Leupold or IOR, but it seems to be a servicable, sturdy scope w/descent optics.  It compares favorably with an ATN 2-6x40 I have!  Claims to be nitrogen filled!  Who makes them?  Where?  What would they normally retail for?

Inquiring minds want to know!!!

Thanks.

Tag for info.

I'm guessing that's made in China, and is probably Airsoft of Paintball gear.  Google "Zos scopes", and one of the first hits is here:

If it's made in Japan, that's a bonus...but the real question is whether it's intended for real firearms or not.  

Zos and REX are the same thing.  Here is their website www.rexoptics.com/index.php .  Here is scope you are looking at www.rexoptics.com/index.php?main_page=product_info&products_id=66 .  I asked about this on optics talk and they said to buy a s&b , leupold and so on.  

The 10x40 side focus they show is identical to a Barska (sounds Ruskie but is all the way Chinese). More than likely this scope is made by them as well and almost certainly is Chinese.

I foolishly tryed one of the side focus scope from Sportsmans Guide thinking that even if it gave me decent clarity to 400 yards it would be ok for woodchucks, I really like the side focus idea, well the best layed plans of mice and men the objective focu wouldnt work for anything farther than 200 yards and even then it was still a bit fuzzy and the knobs could not be re-zeroed, otherwise it was decently clear and I would have kept it if it focused, but I knew better and should noit have wasted money on it.

Burris and Bushnell as well as other make a scope similar to what you are looking at for under $100 typically, a lot of guys are using the 1.5-5 shotgun scopes with diamond reticals for what you are wanting with very good results and you will have a halfway decent scope that is clear and repeatable.
