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

I have allways wanted one of these and now i have one that being said while these are still functional and not needing batteries is a plus you need to realize a modern red dot is more practical and cheaper but these are still cool
Pros:
  • cool factor
Cons:
  • Tinting and dot washout
Would Recommend: Yes
