I haven't used it much since I mounted it. It was easy to zero in. I just hope it holds zero. I did shoot a squirrel with it the other day

clarity, easily zeroed, price, quick shipping time

By DavidFebruary 25, 2023 Verified Purchase

Not a bad beginner scope for cheap, I bought this to get me by for a couple weeks. Holds zero great, it's just not as clear as I would like

Not a bad scope under 100

Better glass

By Logan USAOctober 25, 2019

I picked this up to have an extra scope around in case I needed it, Clarity is good glasses good real nice scope.

Good quality for the price


By JeffSeptember 9, 2019

Not a bad scope for the price. First one I got was not exactly right but AirGun depot made it right and sent me another scope.

By LeroyUSAJanuary 3, 2018

Had to get scope mount that raised scope above barrel due to 40 mm size of front of scope. The Scope is great so far but I have only shot 40 pellets through my new PCP air rifle. Scope gave me a clear sight picture and I believe will be great for target shooting and hunting small game. I was on target at 25 yards in (6) shots.

Easy adjustment, clear sight picture

Need to have scope mounts that give barrel clearance.

By JamesUSADecember 22, 2017

Nice scope for a 3-9x40.Quality made scope

Good quality clear optics good features

By JoeUSASeptember 26, 2017

I mounted this scope on my 25 caliber Gen 2 Marauder and I am very happy I did. It zeroed quickly and stays that way. The optics are crystal clear and I love the easy twist adjustment knobs. I'm shooting 1 hole groups all day long with this scope. I can't belive what a great bargain this is! AND I forgot to mention that it's AO adjustable!

Feature packed AO scope at a fantastic price.

Which mounting rings do i need for this scope for the air avenge??

asked Jeremy from USA

I would recommend getting high 1" rings that mount to a weaver/picatinny rail.

Adam from USA

will this withstand the recoil of an rws 460 mag in 22 cal ?

asked Bruce from USA

I would use one of the UTG true strength scopes for that rifle.

Adam from USA

Is this scope rated for a break barrel rifle, like the Gamo fusion?

asked Nicholas from USA

It says in the description above that it is rugged enough to handle two way recoil from springers.

Kevin from USA

Would it work with RWS Diana 34? What size mounts would be needing? Any other recommendations in scope for Diana 34? Thanks

asked Muhammad from USA

What size rings are best with a Gen 2 M-rod? Medium? High? One reviewer claimed it has the profile of a 50 mm.
