Questions & Answers
For a 25-meter zero using the short-range aperture, how should this be zeroed? 1-inch? 2- inch low? Thanks. Manufacturer Answer

Thank you for you interest in our Troy Dioptic Folding Sights. For a 25 meter zero you needs to be roughly .7” low to be on center at 100 meters. If we can provide any additional information or assistance, please shoot us an email to sales@troyind.com.

Will this co witness an holosun he510c-gr while on a jts m12ak shotgun Expert Answer

The Troy Dioptic Tritium Folding Sight will not work on a JTS M12AK because it is designed for use with a standard height AR front sight. Since the M12AK uses AK style sights and cannot fit an AR front sight the Troy Dioptic Tritium Folding Sight will not work.

Solid. Fast acquisition. by Legacy Reviewer, Verified Owner, August 5, 2013
Like Troy says, you can acquire your target faster with this "diamond" shape aperture than with the round one. I've used both and prefer this.

AR night sights! by ND, August 10, 2015
Awesome sight! Smaller trijicon tritium inserts compared to the front so as not to be blinding when taking your point of aim! Badassery! Also the diamond type shape of the aperture helps achieve centering of your front sight vertically and horizontal...
