Works great - easy to install - Magpul Industries ESK Safety Selector

This works great and it's easy to install. I do prefer the red pins to the black pins to lock in the selector switch/selector lever dealios. I found the sizes and selection to work well for my application. The only reason why I rated a 4-star vs. 5-star isn't the product by itself; it's just that I wish Magpul made a "pro" version that had a metal switch / selector. I don't mind the plastic/polimer touchpoint, but metal would be a nice touch. Note: The rod that goes through the reciever from end to end is obviously metal. Not sure to the material off the top of my head.
