Dyxlesic

I think I didn't explain that very well. The "slow air release" im talking about isn't it's venting through the blast button, but the actual rate at which the air fires from the tank. The hole that goes from tank to barrel is relatively small, so air release is relatively slow. This isn't a problem on it normally, but when expanding the tank, it becomes a relatively inefficien, unless using a long barrel. Multipul barrels magnifies the problem too, becaus the seal As soon as any dart leaves the barrel.
My point is, adding a tank with a faster air release (not faster cycling) would give much better ranges, even if you had the same air volume

But don't get me wrong, I think this thing is pretty sweet, especially for something built from spare parts and leftovers. I'm just thinking of how I would make it better, which is what nerf modders do best

Great job. Reminds me of a mauler from halo. I would think the low ranges are a result of the slow air release rate of the hornet tank, not a result of a bad seal or low air volume. Since you have 3 barrels, in order for it to fire 3x as fast, or a large volume of air is just wasted. I bet an expanded salvo tank would make this thing a great Indoor secondary

I hate to be a downer, but I'm pretty sure the local hardware stores do not carry any advanced pneumatic valves.
There is a guy on eBay selling salvos NIB BIN and he gives huge discounts for buying multipul. he has tons of them. (posting the link is against NH rules) you could also put up a wtb for the BS tanks.
Alot of people seem to be struggleing to get their hands on this valve. If enough people need it, I may buy a bunch and sell them here on the haven.
You could also use the pump and bladder from your RF20 on this project

I had hoped I could use my first post here to make a slightly larger contribution but I'm afraid I simply don't have any breakthrough material at the moment.

Anyway, I absolutely love this project Dyxlesic. I am very much looking forward to the second part of the writeup but as school is approaching I had a few questions so that I may tinker with this a bit before my studies consume what little free time I have.

1. First off, you used a Magstrike valve to fire the ARSCB. Would an RF20 valve be similar enough to substitute? I wouldn't mind getting a Magstrike but I'd rather sacrifice my RF20 since it can't fire all 20 rounds on a full bladder and ranges are lower than just about every other blaster I own.

2. Your design calls for the use of a 3-way valve and a pressure regulator to control the BS tank. I don't know of any specialty pneumatic supply shops in my area, would Home Depot, Lowes, or possibly ACE carry such components and, if so, in what department might they be found? I don't know how it is in your area but the customer service here is atrocious. Alternatively, are there any online suppliers you might recommend apart from mcmaster (I don't appreciate not knowing shipping before agreeing to purchase and I also don't care for minimum orders)?

3. On the subject of the pressure regulator, what would you say would be the best way to calibrate the air flow to avoid exploding any BS tanks while achieving best possible ranges?

Of course, it figures after months of wandering stores wondering why there are all these Fireflies now that I want one the only place still selling them is TRU (for 30 flippin' bucks! Looks like it's ebay time). I'd really like to try my hand at this one and if I can source the valve and regulator for a semi reasonable price I think it's very do-able.

@spencerak: You appear to be correct in that this system could easily be adapted for most auto rotating barrel blasters. However, there is the small matter of adapting said blaster for this system. I believe the reason Dyxlesic chose to build this into the Firefly is because of the unique internals layout that places nearly all of the stock components in the front half of the blaster which leaves plenty of space for the assorted air system components used for the upgrade in the otherwise unused rear portion of the shell. To fit this system into a DTB in a relatively clean manner, you would have to, at very least, greatly reduce the size of the air tank. I'm also unsure of where you'd place the pump if you don't use the Schrader valve idea and a staging area pump.

1: Magstrike triggers and rf20 triggers are almost if not exactly the same. I have done tests with rf20 triggers, and they work great

2: I don't think so. General hardware stores don't usually sell specific valves like this one. I don't think McMastercarr has this valve (but someone will probably prove me wrong). You can get the valve and regulator 2 ways
A. Go to clippard.com and order a MAVO-3 (valve) and a MAR-1NR (regulartor) and barbs with a 10/32 male thread. The shipping will be crazy tho
B. Go to clippard.com and find your closest distributor. Call them, order the parts and either pick them up or have them ship it to you.

3.the regulator is easy to use once you know what to do. The bottom port is in, the side port is out. Screw it in to increase pressure, unscrew it to reduce pressure. It is latterly that simple.

Yes, it will work with any revolving turreted gun. The barricade and even the auto t20 (have the thing that pushes the dart forward hit the valve instead so it's electropnumatic and full auto) would work if you rebarreled, and sealed it.

Part 2 is being delayed because a huuuuuuge leak sprung up, so I'm gonna have to re-hose it. I'm gonna take friendly advice and use the quick release connectors so it won't leak

If anyone has any questions, feel free to ask. If you fear talio-fobic or vacc-fobic, send me a pm and I'll get right back to ya =D

This is cool.

I'd use Magstrike or Rapidfire 20 bladder(s) rather than a PVC hardtank as the average pressure decreases in the hardtank, while in the bladders it will stay the same.

Overall, this combined with Flash's Salvofly (with something like PETG barrels) would be a pretty pimp primary.

This embodies the future of airguns.

I really need to get off my butt and make one. With a Triple Strike tank?.............

If I weren't destroying fireflies for other projects....

It has a regulator, so it's more consistent than any air bladder you will ever buy. It also gives me a much bigger air supply (2x-3x) than an air bladder.
I use stock darts, so it has to fire all darts, but drums can be made out of ANY barrel material. However, the current ranges are incredible

The barbs can be bought for like 10/$2 at homedepot or lowes.

I've had alot happen recently, and I'll finish the writeup soon.
