"I recently bought this for my bushmaster AR15. I love it. Right out of the box I mounted it went outside my home to my personal range. I was locked in on the bull in less then 30 rounds. I think its very easy to use as far as adjustments go. I shot 25, 50, and 100 yards with a few simple adjustments. The only reason I didn't give this 5 bullets is nothing is perfect."

"I Love the OD Green Magpul products. I put front and rear flip ups on my bushmaster AR-15 and I love them. They were very easy to sight in. I only thing I would like to see them do in the future is make a tool to use to adjust the knob for sighting in. It is hard plastic and a sometimes is difficult to turn by hand and a wrench could tear up the plastic. CTD is great prices and service are a win win combo."

"Wanted a good rear flip up sight so i decided to go with Magpul since everything else on my rifle was Magpul. Very happy with my purchase! Installs in seconds without any trouble. Only problem i have is that the knob for adjustment can be hard to turn sometimes. Other than that its perfect."
