Step 1: Disassembling Binoculars

Disassemble binoculars to get access to second lense (usually it is pressed by sleeve)

Step 2: Setting the Reticle

You need to find a distance above the lens, on which you can clearly see anything you put. In other words, you need to find a focus distance of lense, so something placed on that distance will be focused on infinity.

Step 3: Attaching the Reticle

To get a necessary distance, I am grinding some gap in the plastic sleeve above the lense. I make 4 gaps to attach 2 lines, that will form a reticle.

Reticle will be made of one fiber of synthetic rope. Black rope is the best, but if you have only white rope, you can paint it with permanent marker.

So when you grind a necessary distance and fix a fiber on it, you can see a reticle very clearly through the ocular

Step 4: Finish

Assemble your monocle, and congrats, it is a rifle scope now!

It has some disadvantages: you need to literally put it in your eye, to aim on something. And if your rifle has some kickback, you will achieve a black eye. But it works for PCP airsoft without punching you in eyes.

    I was going to ask if this would work on an actual rifle, like .22 or .223, then I saw the last bit. Otherwise, this is an awesome idea!

    I don't think so)) But if binocular is strong, and eye is protected... Maybe

    Using a magnifying glass placed far enough away that it maintains the infinite focus allows you to have it farther away from your eye thus protecting it and creating a proper scope.
