Question: What is the size of the scope tube?
Document: This however was producing very close shooting groups with about 5 different types of ammo. You will not have dime size groups though it does broaden to roughly the size of a quarter----ish.I think that is about all the really important info. Thanks for reading.IF SOUND IS NOT AN ISSUE, BUY ONE ! :)
Otherwise, the scope is really nice, too.
This gun is AMAZING only problem is the scope. The scope will work but it doesn't stay zeroed. Rather than that I love the gun and the power. By the way this gun has some kick.
The rifle is excellent lot of power but the scope isn't any Good every time the rifle shoot the cross hairs move to a different place Good rifle bad scope. I'm pretty sure Mr Michaels would want his name on that scope.
Still anything over 1100 fps with accuracy is awesome.The only downside to it for me is the Sound. Is a very loud rifle. Not Super loud, but very loud.I'll recommend it.May 14th-2013,Rifle is in good shape and break-in with over a 1000+ pellets. The Scope is Garbage. It will hold zero for a few shots.
This gun is very accurate with sighting in to each different ammo. Couldn't believe how different ammo flies being the same weight, just the shape of it. It always groups the ammo but depending on which ammo you sight it to the scope, different ammo is somewhere else on the board.The scope is ok for the use of the rifle unless you like to be super accurate, at first the scope came and the sight picture was turned. So had to disassemble before putting the scope on.
I needed a stronger air rifle to protect my chickens. I wasn&#8217;t sure enough, that my Diana can do a clean job, so I decided to by the Gamo. EVERYTHING will go down with this gun(within 40 yards)I still need to 0 in the scope and other stuff, so I will post more later.Scope is OK, trigger is good, loading the gun is not too difficult, weight is OK.
I know that seems unfair for a product review but it seemed unfair to me to have to pay $20 and get it right as they drop the price. I will update the accuracy and function of this gun but based off other reviews and what I have seen so far, I would definitely recommend this gun (just buy extra pellets lol).UPDATE:Shot it yesterday. Scope took long time to zero in....was off by a lot.
For the money this is a real good gun. The scope clarity is nothing to write home to mom about but if you use lock tight on the mount bolts and make sure the stop pin is secured in the back of it's seat hole, it will work. It took a lot of adjustment to sight my scope in, it was way, way out, you might have crank the adjust dail a couple full turns before you see results like I had to.
This is an awesome machine. I couldnt believe it when I opened the box,I pulled out a well made, solid built rifle. The stock is a comforable durable  polymore stock. The fit and finish is superb , where everything is fit together perfectly. The accuracy is unreal,it can compare to my Webley Valuemaxes. The scope while not powerful,serves this rifle veryy well,but i would, and am going with a larger powered scope.
Answer: yes
