I have no idea how it came out, but I need a roll pin to keep the gas tube from turning freely. What size do I need to get?

From GP's book, 5/64dia. X 13/32 long. It's a solid pin.

Charging handle lug is the same pin, I believe, should you have an extra. As said, the pin is solid, not a roll pin.

I've never tried to coat hanger idea though I see it mentioned often. All the wire coat hangers I've ever seen appear too be to large of a wire to fit the hole.

Oddly enough I just measured some coat hangers. I found one that was just about right, .080 vs. .078. Thanks burtman. I learn something new every day.

No it's not. CH pin is shorter a tad.

Oddly enough, I tried a several coat hangers, but one was too small, and the other too large. I'll keep digging around and see what I can find.

For whatever reason, 5/64 pins seem uncommon - nothing from Grainger, McMaster, Fastenal, etc. I ended up finding a box at a small company out of CA.

I have a metric barrel on a front end, so I'm going to use the roll pin out of that one for now.

+1. That worked well for me too.

Go to your Local hobby shop that sells Music Wire and buy some of the 5/64./.078 diameter music wire http://hobbyhome.ca/product/music-wire-36-078-15/

No drill bits I have would work, so I found another interesting solution. I went through all my hex keys, and found one that was a perfect fit, cut it, and it went right in with some, but not a lot of resistance. The bonus is the gas tube is locked up solid, and a double check of the gas hole shows it clear, so I should be good.
This should solve the gas issue I was having.

The coat hanger works fine, but you have to find one of the older "flimsy" hangers of thin wire. I've done it often, one hanger will last ya forever provided the better half doesn't throw it away when ya ain't lookin". AMHIK :facepalm:

I bet you could also find the right size brad or thin nail and cut to length. I've done that with the rear sight stop pin and at a glance that looks like about the same size.

Tried that but it kept getting tangled with slings or barrels or other stuff, invariably ended up on the floor. The female accomplice of the period was a neat feak..........:mad:

The current lady is much more tolerant of male messiness, which is why she has lasted so long :biggrin: Plus I have stashed spare hangers in numerous dark places, anticipating that they will one day become collectors items and I will be rich :whistling:
