Spring detent fix - UTG Pro AR15 Ambidextrous 45/90 Safety Selector

This selector are just fine for what your paying , ppl are not recommending and giving bad reviews because you don't know what your doing. If the detent is stiff take a drill bit and drill the spring hole in handle a little deeper , do this by hand taking very little out until you get it where you like it , buff the pin with a drimel buffing wheel and metal polish , and it will have a buttery smooth positive lock .your welcome
