Easy to buy, easy to install, works perfectly - Battle Arms Development Elite AR-15 Ambidextrous Safety Selector

My old safety selector switch was too small, and I was not oriented for a left hand shooter. I saw this and looked at the dimensions and it looked perfect. I ordered it and it came four days later and had it installed before the weekend. I did several dry fires and then took it to the range, and it works perfectly. I am not that mechanically, inclined, but it was intuitively easy to install.
