I need to get a roll pin and figured (and was told by a gun smith) that they can be bought at a hardware store. I found a place that carries them but I do not know the specs used. Whats the diameter and length of the bolt catch roll pin?

i believe it is 3/32 x 7/16 i broke one the other day and someone told me the size.  You can find them at some hardware stores.

I guess thats the right size but i believe the length and diameter are listed as 3/32 x 7/16".  A 1/2" one will work.......

You can always cut a longer one to length, bevel the edges and touch up with some cold blue.

What about the roll pins on the sling swivel from an A1 buttstock?  The sling swivel and base are very rusty and I want to remove them for cleanup.  I was able to remove the old (and I mean old) roll pins with some effort, but I am not sure if they are in any condition to go back in the stock.

They seemed to be the same diameter as 1/8" roll pins at the hardware store.  The chart linked earlier does not include stock roll pin sizes.

Thanks.
