I am working on a homemade, but I have gotten vinyl (I think) tubing debris between my barrel and plunger. My plunger is 1" 200psi PVC. I want to try pouring hot, or possibly boiling water down the barrel to try and melt the vinyl, but I am wondering:
1. Is this safe?
2. Will this damage the PVC?
3. Will this work?
4. Will this damage my PETG barrel?

I am not positive that this is vinyl. It is flexible clear tubing that you can buy at ACE. It is 1/4" ID and 3/8 OD.

You cannot melt vinyl with hot water.
Did you not build the gun in a way that allows you to remove the plunger to clean it or the plunger tube?

Well, i am making a FAR variant, but for some reason I decided to attach the charging handle at the front of the plunger. To seal it off, I used the Vinyl tubing over a threaded steel rod. To get them into the hole, I put the charging handle into my dirll and turned it on high power. It went in and melted a bit, creating a better airseal, but I guess some debris got left inside the plunger and is impeding airflow. To take the plunger out, I have to pull the vinyl-covered charging handle out and worsen its seal.

Can boiling water or a heat gun soften vinyl tubing?

Alright, I got bored an decided to expreiment. The hot water didn't work, so I ripped it out and redid it. I will post pics of the completed gun soon.
