I just got like 10 ft of PVC (1/2 in, sch 40) and I was wondering if it can shoot stock taggers or micros properly on a Nitefinder with it.

I would recomend using a crayola marker with some e tape around it and put the pvc over it so that it would make a seal with the foam and rubber tip. That would be your best shot.

You need to nest something in it... Like a crayola barrel.

1/2" PVC pipe.

I recommend 1/2" CPVC (beige/ tanish) pipe for stock darts. Just use 2 inches of that. Or if you plan to use stefans later, try 4 inches of 9/16" brass. You can get it all at True Value hardware stores/ Ace.

So, i nest it on a 1/2 PVC over a Crayola barrel and it could shoot stock darts? Would it be better than just CPVC alone?

Personally, I find that CPVC almost always has a decent fit, whereas other options may or may not work, depending on darts, etc.

Can 1/2 inch PVC fit over 1/2 inch CPVC or should I use 1/2 inch CPVC alone for like a Nitefinder.

Personally I wouldnt do either. The cpvc will fit if you hammer it in. Just find what fits your foam.

So should I get 1/2 inch CPVC rather than a Crayola barrel with PVC nested on it? Also, how does nesting a barrel make it better? And, can you nest 1/2 inch PVC on 1/2 inch CPVC? Thanks in advance.

Nested springer barrels work this way:

1) The dart is loaded into a smaller-diameter inner barrel near the plunger tube.

2) The gun is fired. The tighter fit of the dart in the barrel means more friction, which means that more pressure can build up behind it before the dart starts moving. This means an increase in power and range.

3) When the pressure reaches a level where it can overcome the inertia and pressure of the dart, the dart begins moving. As it transitions from the tighter to the looser barrel segment, the friction drops. The dart then picks up speed as a direct result.

This system is an improvement over traditional barrels in that it allows more pressure to build up from the compression of air in the plunger tube. This greater pressure means better ranges and power. This is why tighter barrels are recommended for springers; they permit this rise in pressure compared to standard loose barrels for air-powered guns.

Generally, CPVC tends to work better than a crayola barrel. It is more uniform and tight on the dart. Plus, there is much less work to do (you only have to cut one piece, rather than hollow out a marker and nest it in a piece of PVC that you also have to cut.).

Thanks so much. So, could you nest PVC on CPVC? Also, do you just put the PVC over the barrel to nest it? Thanks.

Yes, and yes. However, nesting the two will require a bit of work, as it's a very tight fit, and some sanding may be required.
