Ahhh. I see. There probably isn't any way to do that myself is there? I better just get a new one.

Highpower has brought up a very good point. *respect*

I don't "personally" believe that you can not do this yourself if you can make a mild mod, I do respect that from an on line "respect" perspective he is 100% correct.

For $15 - You are correct, and the safest, to order a new one and get as tight a fit as possible.

I do believe that you could make the mods yourself - but the safest way is to order a new one.

Let us know what you do, how it works for you and what the final cost result was if you could please.

I think I'll just buy a new one. I can wait if I have to. It's not worth the risk.

I was thinking the same thing and also wondering if cutting it off on the upper reciever end would mess up the alignment because of the bend in the gastube.

Mind you, I'm not saying it can't be done. But for the cost of a new tube, it just seems impractical to me. Normally you would replace the tube when the "mushroom" wears off at the receiver and causes gas leakage. (Due to misalignment of the tube & gas key...)

J.D. is correct in that, it is no guarantee that you will have cycling issues however. But if you cut it off and the gun starts having problems, the worst you are out is the cost of a new tube, assuming you get it aligned correctly (the bends mentioned above) and don't damage the gas key.

Thinking outside the box, if I HAD to shorten a tube (SHTF) -- I can only think of three possible solutions, and all three involve the use of a TIG welder (not found in most peoples garage) seeing as how you are working with a stainless steel tube. I actually had a fourth idea, but don't know how I would accomplish it. JD: Can we compare notes? How would you go about doing the mod? I'm always up for learning new things.

Big: It's up to you if you want to cut off the end of the long tube and give it a try. I'm sure there are a LOT of folks here that would be interested in hearing the results, if you wanted to do some experimenting. If not - no harm, no foul.

Alright I've done some looking around and I can't figure out what size I need. Can someone help me out? The barrel I got had this description...

"MADE FROM 416 STAINLESS STEEL. 6 GROOVE RH TWIST. BUTTON RIFLED. CHAMBERED IN 5.56 NATO. 1-8 TWIST. .750" DIAMETER UNDER FRONT SIGHT BASE/GAS BLOCK. COMES AS SEEN IN PICTURE WITH BARREL EXTENSION AND EXTENSION PIN INSTALLED. THIS BARREL ALSO HAS THE GAS HOLE PRE-DRILLED FOR YOU!"

Also, here is a picture if it helps...

If you can, mark off where the hole is drilled on the barrel(such as with a Piece of tape or some such thing,
UNLESS the hole is just out side the handguards. Did you build it all yourself?
