Isn't everything removable on an AR, isn't that the point?
So at the factory does anybody or nobody loctite the BUIS? I'd say that if they are on the rifle when it arrives, it better be loctited. I'm not talking red here, just blue. It wouldn't be normal maintenance to take them off, right? I'd put this in the same category as the castle nut. Lots of people swap stocks, should it be Best-practice not to stake the castle nut?
I don't know how the knowledge that BUIS should be loctited damns the OP, but totally absolves S&W.
Yes, it is kind of odd he couldn't find it. I took it he knew when and where it fell off, but maybe I'm incorrect.
Maybe I'm just having too many flashbacks to people picking on the new kid in High School.
