I think mine came from Sears. Give them a try.

5/64 hard to find. Brownells does carry one.

1/16th punch.

You can get a craftsman at Sears for $4.99, or an off brand elsewhere....

I often just use a 1/16th inch drill bit to knock it out..... if I dont have a punch handy.  Works fine, and CHEAP!

I used a small finish nail to drive mine out.  My roll pin punch was getting stuck about 1/3 of the way in and I was getting scared it would break off.  The finish nail worked perfectly.

1/16 is the hole size but the roll pins are larger.

Watch out on the cheap ones, sometimes they snap off in the holes

First time I messed with a barrel I didn't have a punch handy and ended up using a short piece of coat hanger wire.  Its soft enough that you wouldn't have to worry about it breaking on you.  This was on a fairly new rifle but on an older one with a lot of rounds through it this may not work.  I guess this could be the "don't have a punch, no one is open now, and I want to take it apart now" option.

Gas Tube Roll Pin size is 5/56".
You can order ones designed for roll pins from Brownells individually or in a set.  I recommend the set.
Also consider the "Roll Pin Holder" punch set, especially the 1/16" and 5/64" sizes.
Also order a 1/16" "Starter Punch" and use this to "start" the 5/64" Gas Tube Pin moving.
Done this thousands of time...trust me.
