Real Avid Bolt Catch Punch Set - Two punches, one simple solution to the difficult to access bolt catch retaining pin. The orientation of the pin, close proximity to the lower receiver, distance required to safely punch a pin and the difficulty in getting the pin started makes it a real pain with standard punches. Our simple solution, a one-two punch combo specially designed to fit flush against the receiver without damaging it and long enough to reach the pin. It features a roll pin punch for removing pins and a magnetized roll pin starter punch that eliminates the need for a third hand. Smart, simple, frustration free.
