STRAYING ABIT HERE
You seem to stay to plunger alot in your recent homemades and was woundering what the obsession is? Personally prefer compressed air seems to have more power and easier to turn into semi-auto.
Also with things like the fAR i turned that into a compressed air gun and was woundering (in your opion) how big the air chamber would need to be (approx) i was thinking of just turning the stock into it. Do you think this will be enough?

Is it good enough you no longer need the use of o-rings?

Loading the magazine
A video of the magazine being loading. Nothing spectaculat.
Chambering 4 rounds
Closeup of 4 rounds being cycled quickly. I am not firing the rifle between rounds but just cycling them through.
Firing 3 rounds
Here is a video of the rifle actually shooting. I am firing three rounds at a paper target about 35 feet away. As far as I get get in my apartment. You can kind of see the darts in the video but you can definitely see the paper move. the second round just nicked the top of the paper so the paper doesn`t really move on that one. You can also see my cat going crazy with the darts. I only loaded three rounds into the mag and you can see me trying to cycle for a fourth. The bolt is haning up on the dummy round in the magazine, that's why it will not close. Kind of like a bolt hold open, but that is pointless on a pump-action. It does let you know that you are out though.

1) Is the slide made from 1/2" PVC or 1/4" couplers?
2) How long is the plunger? Any smaller then the one in the FAR?
3) How long is the bolt carrier and the bolt?
4) Could you possibly get a diagram up of how long everything is in inches?

I weighed the plungers of my homemades. They are as follows:
SCAR-N: 51 grams
FAR: 110 grams
GNS: 28 grams
The SCAR plunger is less than half the weight of teh FAR. Quite substantial. I threw the GNS plunger amss in there just for comparison. Being a pistol it does not need the catch portion in the rear which is where a lot of the weight comes from.
I`m getting about 40 pounds of force behind the plunger when cocked. Plugging that into F=ma with the above masses for the SCAR and teh FAR. The SCAR plunger accelerates at a rate of about 11500 ft/s^2 while the FAR plunger only accelerates at about 5500 ft/s^2.
The plunger stroke is 4.5 inches. 2.5 inches less than the FAR. The entire plunger length is 9 inches. The bolt carrier is 6.3 inches long and the bolt is 2.3" alone. When the bolt is in the carrier the assembled group is 8.1" open and 7.3" closedI`m not sure what part you are referring to as the "slide". If you mean the pump slide that you grab on to to cycle the rifle. That is a 1/1/4" T-fitting cut to the desired shape. I will get some schematics of most of the part up on my website. Give a little time as I`m a bit busy lately.

Nolan and I are proud to announce that we have an almost-entirley functioning SCAR-N after, collectivley, 50 hours! It's been a process, mostly consisting of Nolan and I yelling at each other in a dark basement while holding various pieces of PVC and sheet metal in our hands. It really has been a trial, but we have an almost-complete rifle now.
The only thing we have to work out is the ejector, and we just need to tirm off the burrs on the slide-handle so it doesn't impede the pumping action.
You seem to be a very busy man, and if you can't currently answer, fine, but we would greatly appreciate it if you could explain the action of the ejector, and possibly take several pictures of the ejector functioning.
We finally got the magazine well to work for us. IT looks nowhere near as good as yours, but it works: it's a plaster mold of our AR-15's mag well, with some spare parts we picked up at the local gun shop. It's pretty sloppy on the outside, but it works well.
I cannot judge how well the gun as a whole works, but it shoots very well one shell at a time (We have to unload the shells ourselves: they won't just fall out if you tilt the gun).
It is very accurate out to ~50 feet, and we're getting ranges in the high 80's.
Once we get the ejector working, we'll start mass-producing the other four so as to outfit our clan with a ready supply of, in our oppinion, the greatest Nerf plunger weapon ever.

Or what about high caliber rifles? Would those work as shells?
I'm nearly certain that high-caliber rifles would not work as shells. Their barrels might though. But who wants to mangle a 50-cal. rifle simply to fire nerf darts from a home-made nerf gun?
But seriously, you should get ahold of the various things you're bringing up and measure them, compaired to your foam and BS's specs for his shells, to see if they will work. And yes, there are stores that sell mags, you might need to be over 18 to get in though (I know Bear Arms, which has an M-60 on the front desk, has an 18+ unless-accompanied-by-an-adult rule).

1/2" FBR fits great in .50 cal shells. I actually got the idea from 50 Beowulf shells. My original idea was to use Beowulf shells but they aren`t cheap to buy so I just made the shells from scratch. Plus you would have to drill out the Beowulf shells to be able to use them. And making an extractor to work with the shells would be tough. 50 cal rifle shells would work but they are huge and you would have a lot of wasted space where the shell necks up. The Beowulf shell is the only productino cartridge I an see working. I guess you could go with the S&W 50 for a rimmed shell.
410 shells are too small at 0.41". 20 gauge is a litle too big probably. Around 0.6". 28 gauge would probably work but I have never actually seen these sold anywhere common.

 no, it looks like there is sufficient width for larger calibre rounds without too much difficulty.

I really should reevaluate my Nerf carreer. I have been ultimated multiple times in a war, shot by a girl with an arced NF, and EMBARASSED by a 6 year old in quidditch on xbox. What am I doing with my life?
