Sorry, no pictures. I know that would make this easier, but I don't have a camera.

I'm working on an AT2K. I'm using four aluminium barrels. I cut the barrels off the turret, leaving only a tiny piece of plastic in the middle sticking out with the attachment pin through it. I then cut a round piece of poly to fit over the face of the turret, with a hole in the middle for the plastic piece with the pin and one hole for each barrel. The barrel holes connect with the one in the middle. I then epoxied the barrels in place.

The problem: there is an air leak in the middle of the four barrels where the holes for the barrels meet the hole for the plastic bit with the pin. A little hot glue would do wonders, but I can't figure out how to get it in there. There is less than a milimeter of space between two adjacent barrels, and they're quite long, making it difficult to get adhesive to the leaks from the front.

One potential solution would be to somehow push the hot glue through a VERY thin straw of some sort. No idea how to do that. I've also seen expanding foam sealant with long and very thin straw-like applicators, but I don't know if they would take the pressure of an AT2K suddenly dumping its air tank on them.

Suggestions?

I suggest using an adhesive that isn't so viscous.

Something like superglue might work better, since you can get it into small cracks via capillary action.

You could try that expanding foam stuff. That may work.

Put some hot glue on the end of a bent paperclip- hotglue doesn't permanently stick to metal, so ignore any that gets caught.

What if you used goop? It has a special fitting for tight spots.

The trouble isn't getting it into the gap between the barrels, it's getting it past the gap.

Not quite tight enough, unforunately. The gap is (after some cursory measurements) just over 1mm in width.

Put some hot glue on the end of a bent paperclip- hotglue doesn't permanently stick to metal, so ignore any that gets caught.

I'll keep this one in mind, though is might be tricky to get large amounts of glue through this way.

I would just say, just pump the glue in there. It will get in there eventually. But it might not look good.

But it won't just get there eventually. The hot glue will cool somewhere close to the top and block the passage; it is much too viscous.

I have no suggestions other than what's already been posted here. However, Frost Vectron's suggestion is the most sound in my mind.

What did you attach the barrels to the turret with originally? If possible I would take the barrels off and re-glue them, making sure to seal each barrel before moving on to the next barrel.

I like to stay away from glues, and if I were you I would find some sort of tube that can fit inside your barrels and just shuve them all the way to the back. This way the tube guides the air past the gap along with covering the gap from the inside.

Wouldn't that completely change the ID of his barrels?

I have a suggestion: Copper coupler things. I used them for my AT3K mod. I did'nt want to saw off the turret and glue on barrels, I wanted it to be REALLY duarable, so I drilled out the AR's from the back, and I chipped out the groves on the inside of the turret, and glued a copper coupler into each stock barrel, then out CPVC on the other end of the coupler. I used 5/8'' copper couplers on the stock turret of teh AT3k. I am sure they will fit inside the turret of your at2k. They make a great seal too. Just put some goop/hot glue around teh outside, it is the most durable thing to do. I get 80' with my AT3k.

It's not like that. I put lube on it and its the same. Its just stuck. And when I cock it back it goes farther back then usual. Also I push as hard as I can and it wont go back in. I've tried the methods and they wont work. Also pics are up.

I then epoxied the barrels in place.



It's amazing what a little bit of reading can reveal.

Epoxy can be removed almost as easily as hot glue, really. Well, mine can anyways.

Really? You must be bonding the wrong surfaces together (materials-wise), or using the wrong adhesive to do so. Epoxy should be a very strong bond, but it doesn't bond to everything.
