After a bit of experimentation, I've found that Buzz Bee's bastard child of an air blaster is actually pound-for-pound a better 4B. The airflow within the tank assembly is much better, making it a fantastic platform to build from.

Here's how to make it Mega-er.

*Materials:
-Mega Missile.
-3/4" to 1/2" reducing bushing, of the totally-round variety(see picture)
-1" to 1/2" reducing bushing.
-1" PVC coupler.
-Vinyl tubing, your choice of size. I prefer 1/4" OD 1/8" ID for the run from pump to tank, 1/4" ID for coupling it.
-PVC/CPVC/ABS cement(Oatey's red can here).
-Tools, you tools.

Let's get started chopping that thing up. Here's what you're starting with:

Take that puppy apart and chop off the pump handle. Let's hope you got an adjustable OPRV, it makes things much more fun.

We need to take a little chunk out of the 1" coupler, so it clears the blast chamber of the tank.

Here it is after shaving it down, being test-fit. You'll need a wrap or two of electrical tape for a snug fit:

Chop off the rocket barrel and solvent weld the 3/4" to 1/2" bushing in place. Remove the check valve in the back of the MM tank(the little black rubber flapper) by cutting or twisting out the nubs that hold it in. Solvent weld the 1" coupler in place WELL.

Build the OPRV assembly as shown in the SVT4B thread here: http://nerfhaven.com...showtopic=20524 . Drill a hole for the tubing to enter the tank and solvent weld both the OPRV assembly and the vinyl tubing into the coupler as shown:

Congrats, you're done. With a tiny bit of trimming of the stock shell, this fits wonderfully in place making for a tiny primary that loves hoppers.

Hang in there for part two, how to make this tank and a MS shell/pump into your favorite air blaster!

Looking good, this wouldn't happen to be going into that magstrike you posted would it?

The one I built for the writeup belongs to Kid_Flash, and is going in his Iron Man Magstrike shell. The other, is going under the knife for completion soon :)

While reading this I somehow managed to miss the part where you said "Build the OPRV assembly as shown in the SVT4B thread". Needless to say I was very confused for a few minutes. However now I have seen the light and it is indeed bright. This is a nice write up and I can't wait to see its final rendition. I do have one question though. What pump are you using and about how many times are you pumping it?

Edit: Clearly if you put it in a MS shell you will use that one. but what are you using for the one in the original shell?

Maybe there's no Mcmaster, but you could make the first coconut airtank.

I tend to use "my" Schwinn pumps with these as well as the 4Bs that I build. I've only been able to find them at Kmart for ~$8 and they're fantastic. Any pump would do however, they don't require massive pressures like a 2k or 3k tank.

The ones in MS shells take 5-6 pumps to pop the OPRV and are getting max slug ranges(ofc), and 130-140' with taerkitty's bumper head darts. I've not tested them with heavier darts, but the performance of these things is great.

Thats fantastic. A bit of a semi-noob question but where are you finding these things I haven't seen them anywhere.

I figured I should post saying thankyou, and I can't wait to be rocking this in an Iron Man MS shell along with the soaker(and eventually the firefly).

You'll be seeing mine (not exactly like this, but similar) too once I fix my frontal leak. :P
