Questions & Answers
Does the listed weight include the mount? Expert Answer

Great Optic at very affordable price! by Casual Shooter, November 11, 2019
I have a few other holosuns across other platforms, although I wanted to try the new (to me) gold dot style. The reticle was a clean yellowish/green hue that was easy to pick up against all the backgrounds I tried it out on.

NO BUTTONS-QUICK DEPLOY by J Berry the Red boi, April 23, 2020
