This guide will take you through disassembling the SGSL, removing the air restrictors, plugging the pump, and creating a coupler system that will accept various types of ammo.
Your stock Signal launcher in box, looks very spyrific doesn't it?
Stock out of the box you have the gun itself, three detachable ammo holders, and three ammo missiles.
The Mirror Missile, featuring reflective coating and a whistler.
The Come Here Missile, featuring flashy red ribbons.
The Message Missile, featuring a rubber O-Ring that you can tuck a piece of paper under.
Whoo hoo. What great spy tools. They all make noise when you fire them.
Out of deference to whatever insanity created this thing, I'm going to hold on to the stock barrel and make a coupler that will let you fire these insane things.
Here you have the contents of the box, out of the box. I'm sure there's SOME use for those ammo holders, I just haven't figured it out quite yet.
Here's the front of the gun, you can see a stock air restrictor there already, but since we'll be yanking the barrel, it doesn't really matter.
And now you have the gun itself, unscrew the whole mess and we'll see whats inside.
Well well well, what have we here? It looks like a BuzzBee Big Blast chamber attached to a tiny little pump!
Well, first things first, lets take the pump apart and see what's up.
The ring on the front of the pump tube is glued on, just pry it off, it's not actually needed, I have no idea why it's even there. When you pull the pump rod out you'll notice one hole on top and two on the sides.
Plug all three of them (there's one on the opposite side too) with hot glue and call it a day.
As for the barrel, there are actually two air restrictors, although the second one isn't particularly effective. Cut the barrel off about 1" ahead of the gray tank and you'll see the gray X.
Dremel it out, and dremel the front of the red barrel out if you plan to use it to shoot the stock missiles.
Be careful on the gray one, there's another piece behind it that's a part of the air release mechanism, don't damage it or you'll have an Ex-Gun.
Couplers, the easiest thing in the world. Wrap some E-Tape around the stump of a barrel until you have to hammer the 1/2" PVC Slip Coupler on, then goop the heck out of it. Easy as pie.
Depending on how close you cut the barrel, you may have to dremel out the opening a little bit to accommodate the larger barrel.
When you replace the pump, just slide the cap back on, there's no need to glue it, you can see here how the tabs of plastic right behind the screw holes keep the pump nicely stuck in place.
To make the stock barrel into a coupled piece, just take a small piece of 1/2" PVC and dremel it out until the stock barrel fits inside. Goop it up, tape it up with some e-tape and you're good to go.
If you want to use CPVC instead of the stock barrel, standard 1/2" Thick CPVC fits nicely into the stock missiles.
Here's the gun all reassembled and ready to go. Be careful about pumping the gun too much, the trigger isn't that sturdy and could break under the pressure.
And the gun all nice and together. I'll be painting this, but that'll be a different post.
Ranges should be about the same as a singled BBBB, it's the exact same chamber, it'll just take more pumps to get it full.
Hope you enjoyed the guide.
