I picked this blaster up at Goodwill the other day (mainly because it still had all the darts!) for something easy to do while I take a break from harder projects. The main advantage (besides looking pretty sweet) is that by eliminating the stock and the pieces on the front the gun the balance is actually better then before. Its the tiniest bit front heavy, but really easy to use one-handed. I'm probably going to cut a bit more off the bottom of the front also.

Here's a nice size comparison. Its only a little longer then a Maverick now. Nothing I did should really affect ranges, but I'm hoping that not having that large orange thing on it will cut down on some misfires.

This was obviously inspired by the mech tommy 20 pistol, but I was afraid to up the voltage because I'm assuming that the rotating barrel and dart pusher are running off electricity also. I never did get the main gun opened up, so there's a slight chance I'm missing something. If you guys have any ideas I would be happy to hear them.

If you want to try this yourself you need to be a little careful cutting off the stock. There's 2 wires that stick past the main body of the gun just a tiny bit. Cut around the screw-hole first and gently bend the wires back before you finish trimming it. The orange piece will slide right out if you open up the front of the gun, but I couldn't make the hinge click like it used to when I put it back together.

Just a little something to give my Auto Tommy a bit more long range. The plungers came out of an old shotgun-type gun that I've posted a couple of times before. It was broken and my repairs weren't providing any lasting fixes, so I decided to salvage the plungers. They are self contained, so they worked great as a pull and release without additional modification. Only one has the AR removed, and the negligible range increase it gave while weakening the front of the tube makes me wish I hadn't bothered.

The range is about 40-50 feet with stock darts (the stefan I had went about 10-15 feet less for some reason) which is about 2x the range of the main gun. For the minimal effort involved, I think it worked out fairly well, and should be more then enough for indoors.

I might finally be pushed to paint this now that it has other stuff stuck to the side.

Nice work! I did this to mine a while ago, and then fucked it up shortly after by attempting to supercharge it. DON'T. The auto-advance overheats and throws off the rotation of the turret, then breaks. The plastic around the motor on mine was melted when I opened it up. Needless to say, I trashed it. I had this whole overhaul with an AT2k integration and everything, too. It sucked. What ranges is yours getting stock?

I just put duct tape over it. If I ever get around to repainting it I would do something nicer with plastic, but I didn't want dust and dirt getting in the electronics while I'm waiting.


Edit:

Thanks! That's pretty much what I was afraid of, so I'm glad I didn't try it. Ranges were tough to do because all the ground is covered in snow, but I paced most of them out to 20-25 feet on the sidewalk, with a few duds at around 8.

Great mod!!! This makes me want to buy two and dual wield them. The grip for this blaster looks way more comfortable then the tommy 12.
good job on minimization.

I have one, the grip is pretty comfortable, though it looks like it was designed for people with only three fingers.

That's how the real Thompson grips looked, if I'm not mistaken.

It's not top heavy at all. The overall weight is fairly heavy, but the balance is good.

Yeah, out of the box they look pretty stupid, I do like the green color though.

It's slightly remotely similar, but it is skinnier. At least this "Tommy gun" has something that's similar to an actual Tommy gun, unlike it's predecessor. Also, it looks pretty cool minimized.

Unkown Blaster

I guess I did only post it at Nerfhq. I did figure out where the spring was supposed to go, but the post was too weak even after epoxy putty and it kept snapping off. I would still be interested if anybody else has seen one though.

If you are to up the voltage you will to get thicker gears for the drums and the add a separate set of batteries to the wheels in the front. If you do (Like I did) the depending on how much voltage (I use a 9.4v RC car battery for the main one and a 8.4v in the front) your gun will shoot much farther and faster. (I got 4.5 darts per second.)

Totally agree, I have 2 vulcans that came with craigslist bundles and a tommy 20 with a volt mod puts a vulcan with a volt mod to shame. Honestly I think the tommy 20 might be the most unappreciated blaster out there because of how weak they are stock.
