Buying a scope for my springer

Hello,
I am thinking of buying a new scope for one of the gas ram rifles. I've been thinking of buying a Konus Pro scope, but I read they were not suitable for air rifles. Really? I thought Leapers would be a good idea, but a friend of mine said "Don't waste your money on a Leapers scope." Apart from that, what is the best objective lens diameter for spring rifle scopes? Is it true that x40, x44, x50 are all bad? What am I supposed to do if all that's true? Use it without a scope? 

What would you recommend I get? The budget is about $140. Thank you, guys. :) 
 
I have had very good experiences with leapers scopes. In your price range, those or the Hawke Vantage series will be your best bet.

By x40, x44, and x50 do you mean objective size? If so, then the assertion that scopes of those objective size are inferior is sinfully false. Many great airgun scopes such as the Bushnell Elite 4200 8-32x44 have objective lenses that size.

If you mean magnification range, then at $140 a scope with magnification that high will probably be unusable past about 20x.

Good Luck,
Nico
 
Gene Leapers scopes are rated for springer use. The function very well, have nice features and have decent glass for the price. I have some scopes on my firearms that cost well over a thousand dollars and in no way do Leapers compare but I will say the last two scopes I bought for my air rifles were Leapers. With a lower price scope like Leapers probably the larger the objective size the brighter the optics. However I always try to select a scope that will be in scale with the rifle. If you want a light weight scope stick with the 1" tube if you would like side parallax adjustment go with a 30mm tube. For general hunting 3-9's ,4-12's are good power ranges. If you want to punch paper go with higher magnification. Bill PS you need a good mount too with a springer. The video I Iinked on the RWS 350 had a very sturdy dovetail to weaver base with dropper compensation.

Just reading about the Hawke scopes on PA and it said to use only their 30mm tube scopes on springers. If people know otherwise let us hear about it. And if that is the case the 30mm tube Hawkes start at about $350 which is out of Gene's price range.
