Home Forums Hunting & Shooting Hunting Optics JG Raider - Kroil on tight rifle scope adjustments?

Follow up from SWFA as promised:

David-

The grease that we use was designed for extreme temperatures. However when it is cold out, on a new scope, I can understand what you mean.

However I have noticed after working the power selector ring back and forth it will free up.
I do not think that a little lubricant will harm anything. You could apply a few drops and see if that will help.

We offer a lifetime warranty on the scope that covers workmanship and manufacture defects. If it continues to be cumbersome to operate, you are welcome to send in to our Return dept. to warranty and we will be happy to inspect it for you.

Please let us know if there is anything that we are able to assist you with.

Best Regards,

Subject: Suitable lubricant for SWFA SS 3-9x42 magnification adjustment?

The magnification adjustments on both of my SWFA SS 3-9x42's is stiff and gets worse in cold weather. I would like to add a few drops of Tri-Flow or similar penetrating lubricant but am concerned about damaging associated o-rings and/or voiding the warranty.

Suggestions?

Thanks,

David

We use Kroil at work as a penetrating oil. When Kroil dries it will leave a very hard tough film that will literally act like a glue. It is a wonderful product for freeing up rusty parts and bolts. It is not a good long term lubricant.

old post but still relevant. interesting posts and thoughts above.

what about whale oil, sperm oil, clock oil? too oily? i like the needle type dispenser. maybe synthetic clock oil? remoil with teflon if you can find it(theres two kinds of remoil)? i have a weatherby scope that has tight windage/elevation adjustments

Interesting, old thread that I had forgotten about. However, I've continued to use Tri Flow in these circumstances and it's worked great with zero issues.

Great old thread and I just ordered a bottle to try on a stiff as hell power adjustment ring on my Vortex Razor LHT.
