The A.R.M. 4000 XL is an interesting twist on a soaker that can be pressurized and fired using only one arm! A working model is unavailable at iSoaker.com for review, thus the only info known on this soaker comes from submitted reviews.

The Arm

The Arm piece is quite solid, and seems to be durable. You flex your arm to pump it. You must first prime it to get all the water out by pumping until there is only water in the tube. The "biceptor" is held on by one velcro and elastic strap, so the Arm is a little unstable while pumping. You may want to support it with one hand. Also, the ARM gets uncomfortable after prolonged use.

The bicep piece holds a small cylindrical CPS bladder, about 3 in. long. Unfortunately, it is unable to grow in length due to the shape of the casing.

A nice design feature is the gun's ability to adapt to one's size. The trigger/grip area slides back and forth to accomodate for the sice of your arm.

On a side note, the trigger doesn't pull very much (only about half an inch), and it snaps open similarly to a Max-D trigger. I'm not sure what the mechanism is, maybe a pinch valve?

The Backpack

While the gun is good, the backpack is horrible. It is a thick plastic sack (like a pool toy). The cap on the backpack is a pull open, not a twist off. I bent over with it on and got doused with water. Also, the way the backpack hooks up to the ARM is another pain. There is a hole in the cap that you stick a tube down. The tube sits at the bottom of the pack. Unfortunately, this tube likes to get stuck, so you don't get to use all of your water. Also, the tube tends to fall off of the gun if not secured properly. The tube is difficult to remove when not in use.

The backpack is also a hassle to get on and off. The strap for the backpack is a single piece, and goes through a loop of plastic on the pack, so when you try to put it on, the strap on the other side slides through and gets smaller.

Pros

-Nice, solid stream
-CPS tech
-Has Backpack
-Adjustable
-Unique design

Cons

-Backpack is a pain
-Not steady when pumping
-Can get uncomfortable

Overall

This is a pretty good gun, it could be better, but it's still good. If you catch it at a good price, you should get it. This gun can probably take on most XPs and smaller CPS. Just be careful around anything as potent as a Max-D 6000 or a CPS 1000.

Side Notes

This gun is from 2002, I think. Also, if you get one new, the backpack is folded up beneath the cardboard.
