You can try to clear this your self. You will need a good sized clear plastic bag, say kitchen trash can size. You will need to get your hands on some nitrogen gas or you can also use carbon dioxide - even try nitrous oxide it should be easy to find at a sports store for paint ball guns . You will need some good electrical contact grease or Vaseline will also work. Take the focus lens off your scope, let it sit and dry out. Now check for any o-rings and try to find new if you can, put the grease on the screw threads at the end of the scope. Put all the scope parts in the bag and pump up the bag with your nitrogen and tie off the bag but leave room so you can screw the lens back on once it has set for a little bit in the gas. This should let gas stay inside the scope so no moisture can get back inside to fog it up. Try that, sounds crazy but it will work.

Can i get one for my 22 air riffle


It is possible to purchase a mount for a standard rifle scope for some models of air rifles. It depends on the brand and particular model of air rifle. However most .22 cal air rifles are not accurate or repeatable enough to justify the expense of a telescope sight..

I have a Bausch & Lomb Trophy Riflescope Balvar Years ago it fogged up while hunting on a cold wet day. I sent the scope in for repairs and got it back, put it back on the rifle and about the third...


most things can be fixed again however at what cost???
the scope should be striped down and cleaned new "O" rings fitted to keep out the damp and then re-gased,,,,pricy job?
you could undo the small screw on the scope body and try warming the scope up to force out the damp air inside it then get some "NITROGEN gas" not co2! and blow that into the screw hole to push out any damp air left in it out and to re-gas the scope,,,,it may work it may not,,,,the nitrogen gas can be found at a camera shop check on the gas first but i think its called "dust away or dust off!" for blowing out camera bodys
dont start a gale inside your scope just jentely blow in the gas

I have a Japan Optics 8x34x56 that doesn't focus at all ranges at all magnifications. Does anyone know where I can get help getting that problem solved please?


There is a guy on ebay advertising scope repair, I talked to him, he sounds like he knows what he is doing. But as far as your scope goes, I don't think I have ever seen a scope go through the entire range and stay sharp unless it cost $1,000, Mine fuzzes out instantly, I just keep it on the clearest setting and leave it there, How many chances or how many times do you shoot it at game and have time to do anything with the scope. I barely have time to aim. Anyway, you might check him out. He might not be advertising all the time. Hope this helps.

Scope fogged up on the inside and i cant see out of it. while hunting in the winter the scope fogged up. now that it is getting warm out it cleared up.


The gas inside the scope has leaked out. Moisture condenses in the cold weather and fogs up your optics when this happens. Send the scope to the manufacturer and they will warranty it. All scope manufacturers have real good competitive warranties. TP

Moisture in my 3x9 Bushnell Banner Scope


In the past, I have successfully dried out scopes and binoculars by them in a warm oven.NO MORE than 150 degrees and monitor them closely.Many plastic parts will melt at high temps and then you have an expensive paperweight.I have dried out my Pentax 12x50s ($300) several times.I should know enough to come in out of the rain but will probably never learn.Good Luck!

Scope


Follow these steps

1) Mount your scope.

2) Use a bean bag or rifle mount and make sure that your rifle doesnt move much from its original position throughout this process.

3) Aim with the scope and shoot at a large backstop which will allow you to see where your shot lands, where ever that may be, it doesnt matter at this point. Again, make sure your rifle doesnt move much when firing.

4) With the rifle in the same position, look through the scope and adjust the crosshairs over to where your shot landed.

5) The scope now sighted in with the rifle. Minimal adjustment may still be required but at least your well within the ball park.

Happy Shooting
