Large front takedown pin questions

[Tigwelder1971]

So you need two pins depending on which upper you use, one pin doesn’t allows you to use both types of uppers is what I am trying ask but I don’t think people are understanding me.

I think we were on 2 different wavelengths, same topic.

The offset pin is used to adapt a small hole (normal) upper to a large hole Colt lower. It will work, but you will have to turn the bolt (the long part of the offset pin) until it slides into the pivot hole. Once aligned, it should go in easily.

I have a bit of experience with these, and you should use blue (removable) loctite on the bolt threads. For some reason, the nut (the short part of the offset pin) wants to unscrew itself while shooting. On many occasions, I have had to go looking for the nut after it fell out. So, blue loctite is recommended.

If you have the money, and you plan to use the offset pins a lot, buying 2 or 3 might not be a bad idea.
