Has anyone had any luck with using pig tail gas tubes? My 7.5 and 10.25 guns jam every round. Thinking its the tube. same prob. if I load one round and see if it locks back. Secondly,,,,,anyone have some inexpensive ones to sell or advice? Thanks.

How do you expect us to help you find the answer to your problem if the most info you tell us is that it jams every round? That is like going to the doctor and saying, "Hey Doc, I am in a lot of pain. Why?". Give us details on what it does and how often and then we can help you. Also specs on the build would be helpful.

There is not nearly enough info here to even START troubleshooting.

Ok, I load a magazine of ammunition into the weapon, fire the weapon, the fired casing does not eject, and in fact is in a stovepipe position, parallel with the magazine. The bolt carrier continues forward and attempts to strip another round from the magazine, jamming the action. It hapens every time. Standard collapsable stock, spring and DPMS buffer.

And the doctor would ask me where it hurts, and I would tell him smart ***. No need to reply, just take the time that you would to reply and go **** yourself.

Load it with one round of ammo in the magazine and fire it and get back to us. We can't tell if its short-stroking without knowing whether it locks back.

Extremely Overgassed.
Increase the extractor tension and try a much heavier buffer.

Your extractor is jumping off the case while it's still in the chamber.
The bolt carrier is cycling and then as the bullet leaves the barrel, the fired case is sliding out of the chamber from residual pressure.
Then the stovepipe occurs because the case is not ejecting properly on it's own as the bolt left it hanging in the action.

Also, what ammo are you using?

Would it even be possible to try to solve the issue by slightly crimping the gas tube using a vice?

Anyone else notice that the OP says he has problems with a short barrelled pistol that has a shoulder stock on it? :TFH:

Maybe he was burnin' some medicinal and didn't know you can't put a stock on a pistol... :chris:


Normally I would MMOB, but what's with this:

I'm sorry I brought it up. Was just looking for a little help. My 7.5 is a registered pistol, without a stock, only the tube. My 10.25 has a permanetly affixed compensator, bringing the length to a legal one. All of the conspiracy theorists can rest at ease. I do however very much appreciate the helpfull responses such as cleaning the tube and port well since I have run some dirty, leaded .22lr through it on a cmmg conversion. It might have fouled it. The buffer is quite light, so a 8+ oz. one is on the way. I appologize to the poster asking for additional information and my less than polite response. Bad day, but not your fault. Thanks to all.

Barrel gas port diameter and buffer weight matters when you shorten AR's below M4 (14.5-inches) in length.
