Easy install - KNS Precision Bolt Catch Retaining Pin for the AR15/M16 w/3 C-Clip Retainers

I recently installed this on a pistol build. It has stayed installed for 100 rounds so far. It is way easier to install than a typical roll pin. I will leave another review if I experience the “C” clip falling off. But so far so good. Leaving at 4 stars until 500 rounds without loss of “C” clip.
