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

Owned several competitors, this is best for all lighting situations. QD is great. The spring mount concerned me but is not a problem. Blacking out the polarizing cap with both eyes open is amazing. Love the triangle.
Pros:
  • Best
Cons:
  • Tidy bowl blue for contrast
Best Used for:
  • all light conditions
Would Recommend: Yes
