My hand fucking swallows them:

They are surprisingly comfortable, though.
On to the writeup:
First off - The internals:

The plunger assembly comes apart like this:

At this point you may be thinking "hey! I can just cut it open at that little seam to get the restrictor out!" NO. Just no. If you cut on that seam, the restrictor comes out perfectly, but getting the barrel back together is a pain in the ass.

The AR. Here's the easiest way to get it out without cutting open the barrel:
Step 1: Drill the peg out through the small hole in the back. Use a drill bit that can fit through that hole snuggly.
Step 2: Drill out the rest of the AR with a larger drill bit. You'll probably need to hold the barrel with pliers while you drill.
Step 3. Punch out what's left of the AR out through the back with a long screwdriver.
Next you can hammer in a 1 1/2" piece of 17/32" brass. It fits in perfectly, and you don't even need any glue.

If you want to, you can also add a 3/4" PVC ring to the back:

This makes it cock like an NF rather than a Maverick. It's just a prefference thing. If you want to do this, however, make sure you have the spring on the plunger tube when you do it. There's no getting the spring on or off after you do this.
Also:

Notice where the spring is in this picture. THIS IS WRONG. The spring is not supposed to go all the way to the back of the shell. There is a groove that the spring rests against that is roughly a cm away from the back. You can see where the spring is supposed to be in the first internal pic.
Here's some size comparison with other pistols:


Stock ranges were about 25' flat. After the AR was removed, it got 30' flat with stock darts, and roughly 40' flat with stefans. After the brass was added, it got 40' flat with stock darts, and around 45' with stefans.
Overall these are very good pistols when you consider how fucking small they are.
Any Questions?
