    What a well made sight. It costs a lot but it is worth every cent. It is very well made, it collapses flat against the rail for transport or storage and pops up with the flip of a button. My big question was did it hold its accuracy. The answer is yes. I have them installed on the 16 inch RF-85 upper I got from Anderson. It took only a few rounds to sight it in and the sights hold true after being put down and raised back up for use. I could easily shoot a two inch group at 100 yds with these sights. I highly recommend them and they will be the only open sights I will install on a rail. Pay the money, you won’t regret it.

    Can you add this Magpul front sight to a rifle with the anderson high rise aluminum gas block? Will it cause this plastic sight to melt from the heat generated??
