The basic mechanism of the STAN gun is the well known hoppered blowgun. The STAN gun is intended to take advantage of this amazingly simple and economical mechanism in a way that more meaningfully passes for a blaster. There's still no trigger, and it's still lung-powered, but there are at least handles and a stock, as well as a flexible tube that prevents the user from getting their teeth knocked out in a collision.
The hope is that STAN guns help NIC-isolated war hosts to provide enough loaner blasters to start a community with normals. There's no question that a traditional hoppered springer NIC primary is a superior blaster for a typical playing field and playing style (These are 50 ft blasters tops), but these are still good enough at what they do to have a role in an NIC war (Provided at least a LITTLE bit of cover) and enough WOW for a person who's never seen homemades to hold their interest. The cost for 1 blaster is a bit deceptive, as very short lengths of pipe are required. This not only means dramatic savings for making more blasters, it also makes it more likely that a given NIC homemade enthusiast would have everything needed to make a STAN gun already. The wye is the only really obscure part, but we've all come to peace with the fact that we need to order a bunch online every once in a while. Schedule 80 pipe can be hard to find locally depending on where you live and if you have a day job (Menards always carried in in Chicagoland, but the closest Menards to me in WA is in Wyoming), but you can always order it online.
I plan on this evolving into more of a writeup than it is currently, but I always do, so we'll see. In the meantime, the video shows you everything you need. I recommend watching it, and really all youtube videos, at 2X speed. It's in the quality settings menu.
Troubleshooting the feed:
+Make sure that the vinyl tubing is pushed in far enough to seal in the sch40 1/2" pipe but not so far that you can see it when you look in the top of the wye.
+Make sure your barrel entrance is as smooth and gradual as needed for your darts. Some darts need more than others. With Artifact darts, you need an extra-gradual entrance. Sometimes tray style hoppers like Zorn's optimal wye are needed for springers, although I've always gotten blowguns to work without them.
+Make sure your darts are short enough. Artifact darts are 36mm, and I think that's about as long as you can go with such rigid foam. If you have darts made with very soft and flexible foam, you may be able to go a little bit longer if you want.
+Take the magazine, and ALL of the darts out of the wye, and put them back in and try again. Hoppers are voodoo, sometimes this just happens.
