ok for removing roll pins not installing 21/04/2018
these are both flat ended punches not roll pin punches. I was able to easily remove the roll pin that I was installing after it became mushroomed and deformed and was unusable. I assumed that a gas block punch kit would have a roll pin punch this was an incorrect assumption but one that set my build back because now I have to get a new roll pin and a proper roll pin punch event though I already bought an expensive gas block punch kit. If you are looking to remove a pin this is good but if you need to install one get a proper roll pin punch set.

I use these punches to remove gas block roll pins on M-16s and M-4s on a regular basis. I have found these tools to be effective for this task.
