When she arrived in the mail I inserted a few megas and was pleased with the air output. The turret seal wasn't the best (SM 1500) but it wasn't bad (Maverick). I'd say the seal is about as good as the AT3K seal. The top half of the gun swivels 180 degrees and then you can pump it up and shoot it like a super-soaker. I knew right away that I wouldn't be using any water (though I still could even after the mods are done) with this gun so I wanted to make the opposite end useful as well.
I cracked her open (uses large screws akin to those of the airjet line) and at first I was pretty dissapointed. Note the size of the blast chamber (about the size of a 1/2" stefans):
I thought, "Man, I'll be getting NO range out of this. Then I realized that the air tank is deceptively large. The barrel going to the tank is all part of the blast chamber, so it's volume is similar to an AT2K or an SM1500.
A bit more excited about its potential, I did a basic barrel mod by drilling out the air restrictors (old style, like in the SF or PC, but they are very easy to get at as the turret comes right out) and slapping in some PETG. I tested it and was pleased with the strong sounding pop of the air tank and the high velocity of the dart. Then it was time to work on the water shooting end.
In the center of the gun you'll notice a cylinder. The pump leads right into this and attached to the pump tube is a cylinder with a hole, (about 1/4") with an O-ring glued around it's opening, facing the front end (where the pump handle is) of the blaster. The piece that fits over this is a cylinder with one end open and two holes on the sides: one leading to the blast chamber for the turret/dart end and the other leading to the water tank for the water end. If you turn the top so the turret faces front, air is pumped into the blast chamber. If you turn the top so the water end faces forward, you can pump air into the water tank. I found that you can pump air into the water tank end, swivel it and pump air into dart end. The water tank will hold the air for only short period of time as it leaks fairly quickly (empties in less than a minute). I looked at the water nozzle and decided that cutting off a quarter inch of it (the narrow tip) wasn't going to hurt anything. Once I did this, I looked down the nozzle opening and it looked no different than any other blast chamber's opening. Determining it functioned the same way as a blast chamber I attached a 1/2" CPVC coupler to it, plugged the pump and put the thing back together.
The turreted end shot like a dream. It takes about three pumps for good pressure and the trigger pull auto advances the turret. The range was comparable to an AT2K and the time between shots is less than that on an AT3K (though you get less shots).
As for the water end, I put a 12" CPVC barrel on it, pumped about 30 times and was pleased with the range (over 100'). The major problem with it was that it was completely impractical because of the reload time. I thought it would be nice to pump it up, swivel and use the turreted end and have a nice back-up shot, but the air leaked too quickly. I figured this was because of the pivot seal (the design just begs to be a bad seal), and I stewed for a few days on the best way to fix this problem. I thought about putting a ball valve on their, cutting open the yellow tube segment and inserting a small check valve, different ideas, but I didn't really want to cut up the shell of such a sweet vintage gun. So when I took it apart to see what my options were, I decided to double check that the leak was coming from the swivel seal...and guess what...it wasn't. I was pleased to see that there was a small check valve just after the opening (I guess there would have to be to keep water from coming out of the pump tube). The leak was coming from the point that connects the water tank to the nozzle (I'm not sure why it comes apart, but it does).
So I threw on some DevCon Plastic Weld two part epoxy (the best stuff I have ever found for NERF blasters) and put it back together.
The seal works great and now I have a new primary. I pump up the water tank before I go into combat and carry the long CPVC barrel with me. I primarily use the turreted end, but if I need to make a long range shot (around 100' as the turreted end still has pretty good range) I swivel the top pop on the loaded barrel and enjoy the surprised look in the eyes of my opponent. This may have dethroned the SM1500 in my opinion (which I do love dearly...I'm fairly positive I have the largest collection of SM1500's) as my favorite primary (not counting integrations).
