Quite simply one of the best tool investments I have ever made. Everyone needs one.

Other alternative uses include: chopsticks, self-defense, or mine probing.

Yep. I have a similar one.

Another option is to drill it out and use a threaded pin.

That'll work but I just use vise grips or channel locks with tape on the jaws to press the roll pins in.

Luckily the billet ones from the 17design lower buy do have a threaded bolt catch.

A strip of duct always worked for me.

There was an arfcom guy that taught his son to make and sell them. His were basically a 5/16 or so rod faced and drilled on the end to lightly hold the pin. The kicker is the hole was offset over to one side so that you could get over where you need it to be against the receiver
