Ok however... - Meprolight AR15/M16 4 Dot Peep Rear Night Sights

Ordered the 4 dot for a home defense carbine build and either it was old stock or maybe the way all the 4 dots are but for the one received the performance was lacking. It was however better than nothing in the dark. The lesser expensive 2 dot version was installed and made sighting clearer and quicker. The 4 dot may work for some people but it just did not work that well for me in the dark. Had the dots been brighter there would be no issues as the sight part appears well made.
