considering one of these 5 scopes

I would take the Discovery (I own) any day, and I hear Athlon is amazing as well. I'd spend money on either before the Leapers/UTG. I owned two of them (UTG) and both gave me problems with holding zero. Maybe the newer ones are better but I just wouldnt put my money behind one again. The scopes that Discovery Optics makes are damn nice for the price.

I was just facing the same decision and went for a Hawke 3×9 40 which sells for a little more money than those. I can reply on the UTG though. I ordered one from Pyramyd and returned it because because I hated it. The reticle was wire and looking like it wasn't square with the body of the scope. And the adjustment knobs were mushy feeling. Overall I had a feeling of cheap construction and poor QC. For what it's worth this was my opinion and I'm sure many others may think it's fine.

Discovery or Athlon, very nice scopes for the money. 

I don’t own a discovery yet, but I have 5 athlon and I really like them for the $$$. I have the 4-16 talos on my streamline. It’s a very accurate setup and plenty of power for your range. 

I have a Discovery scope. My Bushnell scopes have better glass.

Hawke is very good glass, too.

If you welling to wait, you can get the discovery. I'm on my third week waiting for my discovery scope.

I would go with the discovery Charlie at airgun optics plus gives great service and his guns will not break the bank. The sharpness and brightness of the Discovery scopes is as good as scopes costing 2&3 times as much. 

Hawke Airmax. Have then on all of my Springer’s. They are great and service is beyond terrific from Hawke.

I have the first one listed in the original post, and installed it on my TX200. I'm very satisfied with it. When I scope a rifle, I'm not looking for the Holy Grail, and I'm not looking to spend equal to the purchase price of the gun...or more...for a scope. The job is simple. I don't need a bunch of features. I just need the reticle to be usably, and that the point of aim is the same as the point of impact. And that scope does the job. If I ever decide to upgrade beyond that level, probably Bushnell or Leupold will get the nod. They are very high quality instruments that have a long reputation of high quality. But, that's just me, and I'm an OG kinda guy!!!

Hard to beat a Japan Bushnell Trophy 4-12x40 for the price.

I have a UTG on a Gamo Whisper Fusion Mach 1 with a little over 11,000 pellets and I love it. But, and here is the but, before I got this one the gun ate two UTG scopes . One had a crosshair in the reticle break and the other had the ocular lens start to fracture. I had some email communications with customer service telling them how disappointed I was and they apologized. This one holds zero and tracks well which are two of the negatives for these scopes. All were replaced free of charge but it was an inconvenience. But, in my opinion worth it as I will probably be buying another one soon. If I have to send it back a few times till I get a good one so be it. Others though don't want to bother with the hassle and I totally understand that as well. I read somewhere you get about one out of three good UTG scopes. In my case, seems about right.

i have the last one you listed on my bullboss. the VT-2 6-24x44



its really great glass imo.



i liked it so much i bought another VT-2 but in the 4.5-18x44 with a very interesting double crosshair mil dot reticle for my ruger .22lr





charlie (airgunopticsplus) is a great guy to deal with 

BDC reticles are intended for powder burners and the subtensions do not translate well to airguns.
