KNS Precision

Hate mashing roll pins into your brand new lower receiver? How about leaving a nice shiny gouge down the side of your lower as a result of your punch slipping out of its pocket? We do too. Our KNS Bolt Catch Retaining Pin installs in seconds without the need for a hammer or a punch set. Spring tension keeps the pin snug in your lower while the C-clip keeps everything exactly in place where it needs to be. This pin is designed to fit mil-spec lowers. It does not fit most polymer lowers. ***Includes one bolt catch retaining pin and three C-clips*** Pin finish is Black Nitride.
