Has anyone ever compiled or seen a list of the roll pin sizes used in building an AR?  Seems like the local hardware store would be a good source given a reliable list of sizes actually used as standards.

Bigger Hammer's list.

I have found them at the local hardware store. Sometimes the diameter is correct but they're too long - you can cut them down.

Bigger Hammer's list is incomplete. Here is another chart that appears to have all of the AR's roll pins listed, with dimensions.  You can visit a well stocked hardware store and get the right size pins locally.  Pay attention to the diameters, since the lengths can be ground to fit.   I found the big box stores hereabouts had a very skimpy selection.  I had to go to an old fashion hardware store that has a more complete selection of standard hardware, including tiny little roll pins.  Good luck and arm yourself with a good set of roll pin starter and drive punches. - CW

Fastenal has all the sizes you need as well as grip screws and missing fasteners you may need. (rail screws, buttstock screws....)

Both of those charts have some of the items incorrect.
The trigger guard spring pin size is listed incorrectly  and the length of the bolt catch spring pin is incorrect also.

This... why can't we seem to get an accurate list?
