Stock Arrowstorm (very used, as you can tell by the worn down stickers)
The first step is to take off the black grip part. There will be 6 screws you need to take out, then it pulls right apart. There will be two small plastic pieces inside that with springs on them, you will need to keep track of these.
Next you need to take apart the main shell. There are 5 screws holding this down. When you open it, the spring may move, but the other things should stay still. It should look like this.
Just a close up on the turret
I'd like to point out how massive this spring is. I haven't modified many guns, because I just started, but this spring is enormous!
Ok, now on to the turret modifications. You will need to cut out your PETG to the size you want. I originally cut them to 6" each, just to keep it even because I bought it in 1' intervals from OMC. 6" is too long without a spring upgrade. I went with about 4.5 inches each, and that brought me to the rim of the original barrels.
You need to put some electrical tape around the part that will be in the tip, so measure where you need that place, and put 1 or 2 layers around. (sorry for the blurry picture!)
Next, before you put the PETG in, we will be making it rear loading! Drop a permanent marker down the barrel for the rear loading slot. (Just like FA_24 did with his Doomsayer) This idea was not mine, and I would not have thought of doing it to this gun without the Doomsayer write up. So thank you Angel!
It should look like this.
Next, you will need to Goop the PETG into place. Make sure to have a bit covering in between the PETG rim and the extra room in the original barrel to eliminate air leaks. You can also put a little bit of hot glue on the PETG near the electrical tape to hold that side in place.
A combo picture of the turret (Note I did shorten the barrel length to the size of the original barrel, and suggest doing the same unless you plan on upgrading the spring)
The plunger tube head's seal is not very tight. You can help this by putting a few wraps of electrical tape around it. Make sure to keep the angle on the head. If it's flat, then the seal will not be as tight.
Now put it all back together the same way you took it apart, and you're done!
I've also modified another after this. I used 17/32 brass barrels and it worked great.]
The ranges aren't as good as I thought I'd get with a spring that large, but they will work as a back-up. I think I want to carry this on a sling of some sort (like that amazing one by Falcon) along with a longer range blaster.
The ranges are inconsistent along with the accuracy due to the way the gun is fired. It is difficult to pull the back grip backward while keeping the barrel pointing at the target perfectly. It will be a nice gun to spray 6 darts off pretty quickly from a descent range.
I'm glad I did this modification, and like my Arrowstorm much more now that I've done it.
Questions or comments?
