OneKyards. How in the world did he melt a front sight?

It was plastic. Not intended for gas block use.

Ahh ya that makes sense. I use mbus front and rear sights on a couple of my rifles, but they are mounted to the free floating rail above the gas block, so melting them has never been a problem. I typically take 500 rounds and shoot them whenever I go and have never had any problems.

KAC 600m Micro

This! It is the lowest sight that I know of available, has adjustment for windage and elevation for the 200, 300, 400, 500, and 600 meter marks, and is made by Knights Armament. What more could you ask. Its under .4x inches and supposed to be rock solid without interfering with the charging handle. I just posted a thread about whether or not I can zero it at 100 yards and be able to go knock off a hundred from each consecutive if I started at 100 instead of 200 yards.
