Having Trouble Dialing in New Air Rifle Scope

Hello,
Just installed a new scope on my Ruger Airhawk .177.It is a Hammer's
3-9x power.The issue is that when sighting in at 7.5 yards mygroups are 1.5 inches below the desired point of impact.I have the left,and right adjustment,or windage dialed in perfectly.I put 5 pellets into an area the size of a pencil eraser. The height dialis the problem.It's maxed out,so I can't raise the point of impact any further to hit my target dead on.I haveheard that springer,break barrel airguns usually have a slight downward angle of thebarrel,which is common from what I understand.The scope that came withthe rifle I had no issues with.I even tried installing the mounts from my original scope to see if that would solve the issue.No deal!if it makes a difference the original scope had a two piece scope rings,and the new one is a one piece mount.I just wanted to upgrade the stock scope..How can I correct this problem???

I had the same problem.. shimmed the rear ring by folding some aluminum foil and lining the whole bottom part of the ring. I think after all was said and done, the aluminum was about 12 slices thick. This gave me a little bit of elevation to play with.

How to repair a ruger air hawk .177


well for starters, there is no firing pin, second, without major machinery, you can't fix a spring powered air rifle, any of them. It is impossible, major jigs and fixtures hold these things while the spring is removed and replaced. You might try crossman, they do a lot of repairs.

How many ft lb of torque for scope rings


A typical torque setting for scope bases (on a steel reciever) is 30 in/lbs. The rings (steel) need 15-20 in/lbs.

For a aluminum receiver and/or rings, 15-20 in lbs is about max. I use 10 in/lbs with blue Locktite for aluminum receivers and rings.

The magnification adjustment ring on my Gamo Whisper worked fine at first, then was stuck between 3X and 5X. Now it is free again but the scope is not focused on the 3X and 9X settings, but is clear on 5X...


I'm not familiar with the scope, is it an air rifle scope? One stroke type? If not, the backwards recoil of the air rifle is tough on a normal scope, they aren't made for that type of abuse. They work fine with a normal recoil. That is why they started making air rifle scopes. I'm sure that the internals of your scope are damaged somewhat, you can take off the eyepiece no problem, you might find something in there, loose screw, missing screw, you never know, don't get too carried away with the dis-assembly, you'll never get it back together. It sounds like the magnification ring is messing with the focus of the eyepiece. Might just need some oil. Hope this helps.

Scope for ruger 10/22 carbine


Google SWFA ......they sell about 20 different brands of riflescopes, with pix, desriptions and prices. It's a good source for info, even if you decide to buy one of the same scopes at Walmart. Check out the Bushnell Trophy, Nikon Prostaff, and Tasco scopes, in particular.

Also, there is a website I belong to, originally started just for the Ruger 10/22 owners/fans. You can visit it and join for free at - www.RimfireCentral.com
We have a great bunch of guys and gals there, who can help you with questions on ANY type rimfire rifle. I'm sure you will love this site.
