i will try to get a picture up.. but my tube broke at the gas port. half of it is in the front sight and the other part is in my hand. i think the gas tube wore out or it had a defect in it.... but i only put around 4-5k through the upper...

the ammo i was shooting was reloads, but the load is within spec. i know because i just weighed it after i cam back from the range.

let me know.

That is one of the weak spots. You can remove it easily. No worries.

I wonder if the carrier was hitting it on the way back into battery?
It's cheap for a new tube and that little tube puts up with some pretty high temps.

Maybe who ever put the pin in damaged it slightly causing a weak spot.
I have never personally had a gas tube split like that, I have had them wear were it meets the BCG/gas key...and need to be replaced.

But hey, its a gastube...an expendable easily replaceable part right?

Looks like gas errosion and metal fatigue to me. 4-5k rounds will do that. Replace it and it should be fine.

i figured as much... i will just put in a new one and go along for another 4-5krds... it is a blaster barrel anyways. if it gives bowling pins a bad day, im happy :)

After 4-5 thousand rounds? I don't think so. I think the gas tube will last much longer than that. I am sure Randall will be in two give his two cents.

And then some...

Gas tubes are cheap. Buy a new one and sleep easy.

Maybe it was over drilled when it was manufactured? Oh well better a small cheap part go South than a major component! Even better no injury.
