Ambidextrous safety selector - Anderson Manufacturing AR15 Ambidextrous Safety Selector

I not sure if they made this for a billet receiver. But its too long it flops from side to side but when you install the spring and dentent pin it centers up but sticks out some on each side I can not recommend this product! Go for something better! I gave it 2 stars just because I don't like giving 1 star. I save that for the worst of the worst! And believe me they are out their! I will use it because that's how I am! But I will be replacing it just as soon as I can with something better!
