Please rate and comment if you like it! :)
EDIT: It now has an RSCB magazine!!! No pics yet, sorry. Also, forgot to say before, but it has a removable shoulder stock that is insertable by the modified 90 degree elbow you see by the rear of the gun. Complete clearance from the moving plunger handle.
BIG EDIT *PLEASE READ*: I DO NOT take credit for the basic mechanism of this gun. Rork on nerfhaven.com deserves the glory. Now, I built this about 2 years ago and since then there's been an updated, extremely easy to build (if you got a dremel, a few common tools, and a hardware store, you're good) new version on Nerfhaven right here.
It works like a nerf nitefinder, only large scale. You pull back the plunger to prime the spring piston inside, then press the trigger and the rubber plunger head springs forward, pushing out a volume of air, to the barrel and the dart, which flies out. JUST GO TO THE LINKED SITE.
I just added my own mods to it - the foregrip, black paintjob with camo tape, slightly modified plunger rod just using what i had, and iron sights. You can do whatever you like to make it look how you want it to. Just so long as it works.








































Also, the spring I'm not sure what company it was, but it has the spring names that start with C-xxxxx (x being numbers) and come in packages with yellow tops. I used two springs about .5 inch OD, .080 wire thickness, and 6 inches long - total 12 inches long uncompressed. The springs were bought at OSH.
It looks awesum!
In a comment below by me, I gave the site for building the gun (not on instructables, but clear enough). My addons were just the camo tape, which was wrapped around parts of the gun and then trimmed with a hobby knife to fit the nooks and crannies exactly.The front handle was a modified pvc tee zip-tied on... Basically, all the special parts you see (muzzle sight, front/rear gun body sights, front handle) are modified PVC - be it fittings or the pipe itself. If you still want some specific pictures of certain parts of the gun after looking at the instructional nerfhaven thread below, PM me.Sometimes my answers take a while though, sorry ;)
I basically made it by using a dremel sanding drum to sand away some of the inside of a small section of 1/2" PVC, then I get a 3 -1/2" (or however you need to fit a stock dart with a head that's bigger than its body in there) piece of CPVC or crayola barrel or some other barrel material and stick it in the newly widened end of the PVC. It's important that that cpvc is snug and tight in there and straight so it won't fall out. But yeah, that's how I made a stock dart barrel for a snapbow. (then, of course, you just remove the barrel shown in my pics and stick in the stock dart barrel)
I just modified a few parts to fit what I could find.
I thought of front and back sights (out of heatened + flattened PVC pipe, basically crude PVC sheets), the barrel is based on Zero's "unknown breech" (look it up) but I added the muzzle sight part, and my own removable stock and front handle ideas, and I thought a black paintjob and camo tape would look niiice. :D
