Vortex viper & trybe g26 slide combo - Vortex Viper 1x24mm Reflex Red Dot Sight

I bought the combo of the slide and the viper red dot since they had a deal at the time on OP. When I went to install the red dot, the dot wouldn’t sit into the slide without me having sand out some material. The tolerance on this might be just a bit too tight with the slide. Anyway, after installation, I notice that the red dot itself has a terrible refresh rate on the lower power settings. I would have to turn it up super high to get it to not have low refresh rate, but that’s a potential issue in low light condition due to the blooming of the dot. I would recommend going with a Holosun if you’re on a budget, or just get an Aimpoint or Trijicon. I wouldn’t buy this again.
