Nice ambi safety selector, no screws - Magpul Industries ESK Safety Selector

I like ambi safety selector switches. I have routinely used another brand, until recently. When I went to remove one of the other brand switches to install a different trigger, the Allen head retaining screw heads striped out. I guess you can use too much blue locktite. The Magpul ESK does not use retaining screws. The plastic selector levers fit over the ends of the steel selector barrel and are held in place with plastic pins, which can be removed with a small punch. I like this concept, although time will tell if the plastic pieces hold up. Very easy to install and remove. I've only been to the range once since installing the ESK, but it worked flawlessly. The throw is very smooth. I would recommend this item to a friend. I would have rated this a 5, but I'm a bit concerned about longevity of the plastic pieces. So far, so good.
