​Can this scope work well on ak 47 caliber ..308 caliber and .7-62×54 caliber

Excellent.

You will love it :)

Thank you. That will be a good budget long range setup.

Thanks for that info. It is my first Discovery scope and I am happy to hear good feedback about the reliability.

Thanks for the feedback. I is nice to know that they can handle springers as those are the most demanding. we air gunners know more than well.

In that case, Vector optics Continental would be a better option for you.

Hi. Thanks. I haven't tested it yet, so I cannot say...

Yep. I love it.

I actually explained this in one of the comments... In short (and in my opinion), Discovers is almost the same in performance as Vector. The things I would mention: Discovery's adjustment clicks actually feel better than Vector's. Discovery has slightly worse image at minimum magnification, the image is in perfect focus in the middle of the image but not that good at the edge, but in my mind, that does not matter anyway as no one will buy 30x scope to use it at 5x. At full magnification, pictures are very similar - very good.

It is very similar. Continental is slightly better at 5x and it is easier to find correct eye position on 30x than HD gen2. Elevation and windage is actually better on HD gen2. So considering the price, the HD gen2 is the winner in my mind.

@gregorkamensek3923 another advantage of the vector is that the paralex starts at 10m vs 25m for the hd2 which makes it more airgun friendly I guess

@@ziadkadiYeah, maybe, although, I don't know the last time I shot with an airgun at 10 m and if I did, I definitely did not use scope of this size :) I don't even shoot with the pistol at 10m... LOL

@@gregorkamensek3923 ya lol

This is quite a serious mod and I do not advise you to do it if you don't know exactly what you are doing...

@@gregorkamensek3923 ok gregor Grazie mille era solo per sapere se e il buco piccolo che c’è sulla valvola assistita da bucare Grazie 🙏🏼🙏🏼🙏🏼

@@matteopierotti7687 The mod would required to extend the hole (not make it bigger) in the front cap where the valve is trawling to make more volume. More volume in that cup will result in valve staying opened for longer time. You can maybe contact RTI and ask them if they maybe offer an already enlarged cup. This way, you will not risk destroying yours :)

@@gregorkamensek3923 Grazie mille gregor 🙏🏼🙏🏼🙏🏼

LOL. I have actually put a (rifle) scope on GK1 to start testing accuracy but I used a bis smaller scope :)

I use smaller Vector optics scopes, typically Veyron sometimes also Taurus. This scope is a little too big for K1 :). It would work of course, but it would look funny...

@@gregorkamensek3923 One more question, do you know the WEST HUNTER optics scopes?

@@user-di8lz6sk6p No, I don't.

@@gregorkamensek3923 Ok, thank you very much for answering my questions.

LOL. Thanks. You know I tried to google it but I could not find the word... I have problems with my vocabulary when it comes to optics :)

@@gregorkamensek3923 By the way Gregor, is the U.S. version of Huben GK 1 the same as yours ?regarding its power (FPE)!

@@domingoliao2724I assume so. This type of valve is reaching theoretical limit of power that can be achieved. I can get about 82 fpe in .25 and 70 fpe in .22. I have seen a video that achieved 91 fpe in .25 but I assume I had slightly lower pressure when I got 82 fpe...

@@gregorkamensek3923 So the U.S. version of GK 1 are one or the same as what you have?as of the Huben K I .22 cal.what particular brand of pellets will do ?

@@domingoliao2724Same products for all markets, but they do already have few versions. I have version 3, US probably mostly have version 1. You can see the marking for version on mine "V3". The differences in versions are minor and don't have anything to do with power. I will shoot any pellet and slug, limitation is 11 mm in length to fit in the magazine.

Yes, it is at least on mine. It is also nice that the ends on each side are "hard stops". It does not feel like you are squeezing the spring in any excessive way.

I completely agree.

Well it depends on the use, application and preference. I too can see reasons that you would like to lock it but for my use, I do not need locking.

Thanks for the input. So far I don't have any issues and as you mentioned yourself, I might get more help than other customers when/if I do because I am a KZfaqr. Anyway, I am sorry for your bad experience.

@gregorkamensek3923 yup, you maybe right on that part. I'm just saying this is a lawsuit waiting to happen. That lifetime warranty is bound to fail. Hope all bad experiences for customer service will come up. I'd buy from other brands and endorse other brands. If the lawsuit comes, you may never know. Anyway, like I said just a fair warning.
