Stan's Review of ZeroTech Optics Thrive HD Series RMSc Footprint 1x21mm Micro Reflex Red Dot Sight

Fits the 43X MOS perfectly. Rubber cover does not fit, too loose and falls off. Needed to trim the rubber cover to make it fit better.
Really nice Optic with a low profile so the factory iron sights can still be used.
Pros:
  • Nice low profile
Cons:
  • Rubber cover does not fit
Best Used for:
  • 43X MOS
Would Recommend: Yes
