The powerclip. The case looks stupid. I'm going to paint it black one of these days. Open it up. There are some screws that are different sizes. You may want to separate these from the rest. I didn't, and I haven't had any problems. The screws in this gun are also prone to having their heads broken off, so go slowly.

Here it is open. You can now take the clip out.

Using a hobby knife or something, cut out the x-men symbols on the back of the clip. I have done this, and now I can shoot stefans and the range is a little better.

The infamous removable clip mod. I haven't done this because I only have one PC and I don't want the clip falling out. If you want removable clips, file, cut, or sand those ridges on the end of the clip down so they're flush with the rest of the clip.

Here is the hose clamp on the air bladder. You're going to hate this thing by the time we're done. Unscrew those screws and take the two halves of the clamp off.

Here I've taken the clamp off and you can see the air release valve. You need to get that out. It's in there pretty tight: I recommend taking the pole section of a screwdriver and prying it out. Try not to scratch or damage it, because you'll need it later. Don't use pliers :).

OK, here the air release valve is out. Now, you want to use a sharp knife and cut about one inch off the end of the air bladder. If you cut more off, you'll get more range at the cost of less shots. If you cut less off, you get more shots with less range. The guy who actually created this mod says that one inch is the best length.

Here I've cut the inch of the air bladder off. You won't need the part you cut off.

Put the air release valve back in. This is a lot easier than taking it out; just push it in and it goes in. Next is where it really gets tough.

Now you need to put the hose clamp back on. This is tough. Take one of the screws that goes to it and put it in the top-right hole. Screw it down (this shouldn't be that hard). Now do the other top screw. Don't screw them in all the way--about half way is good. Too little and they'll come out, too much and you won't be able to get the bottom screws in. Believe me, you will have plenty of times to get it right ;).

Here I have the top screws in. Now comes the hard part.

I used a pair of pliers to hold the sections together while I screwed the screw in. If you can, get a friend to hold the pliers. If you can't, brace the bottom handle on the casing of the PC and screw the screw in with your other hand.

I've done it!!! At this stage in the mod you will want to damn everyone at Nerf to hell. Of course, it's your choice to do this mod. You still won't be happy. I wasn't. Anyway, make sure the screws are tight so that it won't leak.

Put everything back together and take it outside, and you will (hopefully) see a 33% increase in range! Apparently, accuracy is decreased a little, but it's more than worth it. I recommend this mod if you want to use your PC outdoors, but inside, a stock PC is just fine. If you only play inside, don't do this mod; it's too much trouble. I love it though :).
