The symbol on the side means "greater than average" in mathematical terms.
I attached this to the stock nitefinder plunger rod with washers on either side to ensure it isn't ripped apart by the spring. I clipped down the edges of the bathtub plug so that it still has a great seal, but slides very easily through the plunger tube. You are going to have poor ranges if your plunger rod doesn't move quickly- regardless of how good your seal is.
This blaster has a super cool holster too. I got the idea when koree posted this writeup on Nerfhaven. A magnetic holster sounded pretty cool to me, so I thought I would try it. The dots epoxy puttied on the side of the blaster are the magnets, which attach to the magnets on this strip covered in duct tape like so:
The strip has belt loops in it so that it is actually usable as a holster. I can run around with the blaster attached with no problems, even when jumping. The magnets do yield when I pull the blaster off to fire- it would be kind of embarrassing if they didn't.
Because I have so many different barrel systems that I use on nerf guns, I wanted to be able to use the widest variety with this blaster. It is my primary after all. I installed a universal coupler system so that I could achieve just that. Getting the cpvc coupler to stay in was a pain, but I finally got it to stick using gorilla glue. Now I can use a super modern speedloader! They have the highest rate of fire ever!</sarcasm>
