First off, I apologize for my "helplessness", but I just ordered the plastic tubing from McMaster Carr, part number 2044T43.
Of course, it's not true PETG (or so I'm told), so I don't need fancy tools to cut it (which I don't have).

It says on the website I can cut it with scissors but I don't want to break my scissors.

I have pipe cutters, but they're the cheap kind that give you an angled cut in the end. What I'm asking is can I score the tubing with the pipe cutter and use my scissors to cut it?

I use a hacksaw. Cut carefully.

I think it is actually the PETG used by most nerfers, as for cutting it, I did a quick google search, and came up with an already existing thread about that exact subject, on Foam Universe.
Hope this helps.

I wouldn't advise using scissors to cut these, although I'm sure it can be done. I don't know of any pipe cutters that give you an angled cut, but you can cut the tubing with whatever pipe cutters you have. I would advise using the twisting around and around and periodically tightening method that is used with this kind of tubing cutters.

You can still use that method with these kind of pipe cutters.

Just shearing straight through the pipe with scissors or pipe cutters might crack or damage the pipe.

Another method is using a scroll saw. OneManClan used this method to cut hundreds of feet of PETG back when he used to sell it. And as said by Naturalman7, you can use a hacksaw too if you want to. You will most likely have to deburr the ends once you are done cutting, though.

The difficulty of dealing with PETG was one of the reasons I began using CPVC. I used to use a hacksaw then about 20 minutes of sanding whenever I dealt with it. I haven't actually tried this but if I recall correctly you can make pretty clean cuts using a piece of 17/32 brass and rotating pipe cutters (the wheel one, not the knife one.) Roughly cut the PETG with some extra out, insert the brass, and then you can use the roller cutters without crunching the PETG and smashing it.

Hey guys, got 1 more post for today, when I received my tubing I just made it have at tight fit in the second cutter dartslinger posted, and then scored the tubing until it fell off.
Thanks for all the suggestions.

Get a piece of rod (wood/nylon, whateves) 1/2 inch wide. Insert into pipe where you want to cut, and use mini Pipe cutters. It leaves a nice straight edge and does not deform the PETG.

I tried using this method at first, but for some strange reason, my PETG (2044T43) would not accept 17/32" without hammering it into the PETG and deforming it. I was surprised because many people had done it before with no problem. Does anyone have the same problem?

I do. It made making a rearloading AT2k that didn't drop darts out the barrels more difficult. I think it's because of the QC of McMaster's tube.

The 1/2" brass from McM fits perfectly.

Thanks, I had suspected that but was not entirely sure. The AT2K I overhauled had the same problem.

That makes sense as the brass is smaller, I may try that too.

I use an ald AAA battery, wrap M-Tape (white paper based masking tape) around it until the battery+tape fit snugly into the PETG, then use the twist-twist-twist pipe-cutters shown above.

Of course, you could use any cylinderical object other than a AAA battery, like a pencil.

works a treat.
