guy's Review of Meprolight M21 Self-Powered Day & Night Reflex Sight w/ Dust Covers

Same as others have experienced . Sight base is spring loaded. Moves too much for my comfort. Not sure why it’s designed that way but not a fan. Overall seems to hold but it does move around if any pressure is applied.
Pros:
  • self adjusting brightness
Cons:
  • Base/mount is not very good
Best Used for:
  • Someone else.
Would Recommend: No
