(Edit: It has come to my attention that somebody else already did a brass barrel replacement on this gun, so that's not a first.)
The gun module:
There are four screws on the other side. Unscrew those and it will pop open, no problem. No glue. Just watch out for the catch's spring, it likes to come out.
The internals. About as simple as they come (I flipped it around from the last picture):
The arrangement is essentially identical to that of the NF.
In addition to the air restrictor, the opening at the barrel-end of the plunger tube is horribly small (this picture is taken from the back end of the tube):
The spring and plunger:
One screw holds the plunger head onto the rod. Unscrew that and you can add a new spring.
With the new spring added:
Now, the barrel replacement and AR removal. The AR is in the middle of several glued-together pieces, one of which is the barrel. I decided to simply cut off the barrel, allowing access to the AR. Once I removed the AR a new barrel could be inserted.
What we're working with:
I cut around the barrel, removing it. This is with the barrel removed but AR still in place. There is a small lip which holds it in.
I shaved around the inside of the opening that is now there until it was large enough for a piece of CPVC to fit in. Incidentally, that also enlarged the hole enough for the AR to come out with a bit of cutting where it is attached to the sides.
I didn't like how small the hole going from the tube to the barrel was, so I similarly enlarge that by shaving around it with a knife. You could also just drill it out.
With that done, I simply hammered the new CPVC barrel in and glued it in place. I should point out that you have to be careful how long you make the barrel, since one which is too long will not allow the module to fit into the gun's frame.
Re-assembled the module.
And popped it into the shell.
Ranges are good, though I have no way to measure them currently. My estimate would be between 50 and 70 feet, but that could be off. Either way, its power is increased significantly by doing these basic mods.
