I stupidly ordered a gas tube that is to long for my barrel.  Has anyone ever just cut one down?  If so how did it work?  It's not a big deal, but I hate to pay for shipping etc on a gas tube.

Thanks
Dan

It's not really practical to try cutting it. On one end you have to preserve the mushroom and on the other you have to worry about the curve of the tube.

You can't cut it.  The gas tube has a flange at the end that's designed to form a seal with the carrier key.  Unless you have the tools to make this flange, you're better off buying a new tube.  On the bright side, if you ever decide to swap out a longer barrel, you'll have a long gas tube handy :)

i've done it and it's no big deal.
i cut the end that goes in the fsb to length, then plugged it with a ss rivet from ace.
then drilled the vertical hole in the tube for the gas. and the horizontal hole , through the tube and the plug to hold it to the fsb.
drilling this end leaves the flare and the bend alone. works great.
necessity was the driving force, as there were no mid lengths to be had at the time.

Thanks, I had to order some other stuff so I threw the right length gas tube in.  Hate to wait on it, but it was my stupidity that ordered the wrong one in the first place.  Oh well as first build screw ups goes it's not the end of the world, just annoying.

The tube is not flared on the end. A portion of the tube behind the carrier key end it is reduced in size. Probably to reduce friction and/or binding if the tube was fulled sized the entire length when inside the carrier key.

I remember that. It took me over a month to find a mid length gas tube.

I have a stockpile of them now.

Just buy a new gas tube; they are cheap. Don't bubbasmith your tube.
