Merit Optical Adjustable Aperture Sight for Shooting Glasses Handgun Target

Description

These are no longer made, but at one time were extremely popular for decades among iron sight handgun shooters.   I bought this many years ago but never used it.  Has an adjustable aperture to control depth of field (second photo is with aperture wide open and third photo is closed to pinpoint for sharpest focus).  You place these via suction cup on the dominant eye's lens of your shooting glasses lined up with your vision and then adjust the aperture for light and depth of field.  Allows rear sight, front sight, and target to be in sharp focus.  Aperture can be swung out of the way for normal viewing and then swung back again for shooting.  These are "new, old stock".  Very hard to find and in perfect working condition.  Shipping is USPS first class to USA ONLY.   No foreign sales.
