Replaced plunger tube Nitefinder

I've been doing some experimentation with Nitefinders recently in the hopes of making something noob friendly and war worthy. I have two Nitefinders and three different plunger tubes all of which can be swapped out for another.(You might notice the shells change colour)



I've extended the draw as much as possible with the stock plunger rod but that could change with the addition of a homemade version I'm working on. However I like the fact that pretty much anyone could make this blaster which wouldn't be the same if it required home made parts. (The plunger tube is so simple anyone can make it)



I'm using a 16mm coupler at the moment but my next one will be 20mm. (Clear PT too)



The plunger tube is 4" long and 23mm in dia. (as opposed to the stock 24mm) The coupler adds 3cm onto that. Since the PT is smaller it works perfectly with the stock seal, no mods needed.

it's a pretty good mod keep the good work up

So what is the material used for the plunger tube?

Sorry about the late reply, I've been on holidays : )

The plunger tube is made from either 25 or 30mm PVC, can't remember which. (I sanded the detail off) Just find the size that has a 23-24mm ID.
