  1. …and mine went flying, never to been seen again.

    While I didn't have this particular tool, I had one but it the bolt wasn't seated properly, backed out and was aware but the spring and ejector had other plans.

    Well, another order from Brownells!

  2. I guess you have never worked on the AR15 or replaced an ejector spring before. My comment was directed to the fact that he hits the roll pin directly into the bolt. Brownells sells a roll pin holder specifically for holding the roll pin so it can be tapped into place. When you hit a roll pin directly with a hammer you run the risk of "mushrooming" the top of it. As to whether you have seen them used over and over is irrelevant. In the military and in professional circles they are not re-used.

  3. Like the rest of the rifle, Stoner designed the bolt's pins to stay trapped during use. Staying inside the bolt carrier, the extractor and ejector pins cannot come loose. If you look at the rest of the rifle, you'll see that his design is all about reducing the risk of lost or loose parts because they're all critically trapped by something else. So long as you don't damage a roll pin, I've seen them used successfully many times over by competent smiths with the right tools.

  4. FYI- This is not the correct way to do it. You are supposed to use a roll pin holder and a roll pin punch when re-installing the roll pin If not you risk damaging the roll pin due to their size. In addition you should not re-use a roll pin especially in a critical piece like the bolt as they can work loose.
