hey guys did a search and found nothing, looking for help. bought a brownells metal enhanced saftey switch for my mossberg 500 persuader, at the moment the gun is fully disassembled on my workbench and i am stopped in my tracks on further progress on my saftey install. mossberg for some silly reason has the factory saftey installed with a one-way screw(it can only be tighted not loosened) really weird never seen this before. what i'm gathering is basically you have to break off the plastic safety and use pliers to remove it. so before i go taking a chisel and hammer to my new gun does anyone have experience with this clusterfuc%??? the brownells instructions are very vague but im gathering they want you to snap the old one off with out actually telling you to basically damage the factory part. i'd rather have a crappy saftey than none at all. it's sunday night so i dout theres someone at brownells for tech help. help!
