I really like these by mikemNC, Verified Owner, February 22, 2025
Installed without a hiccup, I am able to acquire my target much easier and much quicker, very happy and I wish they made these for the G48 so I could put them on that one too, I recommend them.

fast dot not working well by Dirt, Verified Owner, January 25, 2025
I was disappointed in the way it worked. Takes too long to line up the sights. I would not recommend it to anyone.

HiViz Fastdot H3 by DM, Verified Owner, October 25, 2024
This was a real disappointment. The green dot you see when the sights are aligned are no where near the brightness you see in pics and the video they refer you to.
