Pig Tail Gas Tubes

[SinnFéinM1911]

I read the thread by K.L. Davis entitled "After you pull the trigger"

** Which may I add is one of the best threads I had ever read and learned from on the net !!

I was looking for feedback on Pig tail gas tubes and peoples experiences or test complete with them. From what I read, I really like the idea.

I had a chance to talk to and hang out with 2 guys last summer who spoke of them, and they held them in pretty high regards.

I was looking into pricing on them and the few I found were over $130… is this about right for these ?

Any thoughts ??!?!?!?

avoid them

Pigtails are, in my estimation, a band-aid fix... largely treating the symptom not the cause.

However, they are in theory a pretty clever idea, but I am not a fan of the ones that are on the market -- the biggest reason being that they are a coil and subject to changing size and shape as they get hot. You know that gas tube alignment is a pretty picky thing with some guns.

Yes, there is one that is anchored on both ends and is actually a pretty slick little piece -- my big problem is that for the close to the cost of one, you can replace the barrel with a mid length gas system

The PRI fatboy has all the advantages and none of the drwbacks of the pigtail. Plus it's cheaper.

I am even less of a fan of the expansion chamber designs...

I had the chance to see one that was cut open after several thousand rounds and it had carboned up pretty good inside -- point of concern, an expansion chamber will carbon up.

Not long after that, I saw a weapon that had stopped working -- It had a small piece of carbon blocking the gas port between the bolt key and the bolt carrier.

That gun also had an expansion chamber gas tube.

To be totaly fare, I can not blame the expansion chamber tube, but I certainly can suspect that the tiny little piece of carbon *could* have originated from the chamber. Also, it was only once and I have not seen it again since... but I do know for sure that a tiny little piece of junk did turn the gun into a single shot, and it was not something that is a quick fix.

Bottom line... for me, if my life depends on the weapon, I would prefer to eliminate the possible problem. And again, it is treating the symptom, not the problem.

I've run a PRI Fatboy on a 11.5 and 14.5 Colt (suppressed) guns. They work for the intended purpose -- but I do agree that a midlength gas system in much prefered -- I did not know about the expansion chamber carbon depositing -- but I guess that is basic science when you think of it - thx for that.

KL, how do you solve the problem in the Commando length guns? Piston systems?

Anyone have experience with ArmsTech's gas trap system?
