It's really nice to see you've posted this!! lol, I'm posting mine in about 9 more days. It will be my Christmas present to the k'nex community. Even though I don't plan on building this I at least get to see how it works. I'm more into guns that are powerful enough to put a hole in your bedroom wall. I'm sure your mom would kill you if you did that XD. If one day you decide to build one of those, I recommend you go outside with them. Still a cool gun you have there.

Well, what is the use of a gun that you cannot shoot inside? I mean seriously...? If you cannot take your gun and nOOB-tube your little brother, whats the use? XD I like guns that have power, but you must sacrifice a lot to get a good and powerful gun...like yours...? O.o

Well, you know how the story goes, or should know how it goes, I would think you've been on ibles long enough to get some sort of experience to know a few things about k'nex. The point is, some k'nex guns are too powerful to be shot inside your house, and can cause some serious damage to things you don't want destroyed. Trust me, I learned real quick not to when I built the TR-18. The TR-18 shot its way though about 3 walls in my house with 10 rubber bands on the firing pin. It had zak's stock on it. I wouldn't recommend shooting anyone with TR-18 or any other high powered k'nex gun. Seriously. Don't do it.

I kind of figured you weren't X). I just realized something: I guess it's okay to shoot other people with a TR or other high power gun as long as you use ammo that won't kill something and you don't put a lot of bands on the pin. That's why most k'nexers ban fin ammo/sniper rounds from k'nex wars due to safety concerns. I would think that the only way fin ammo would be allowed is if you're having a long range k'nex war, 100+ ft. Most wars only take place around 50 ft.

XD. You figured correctly. Well, you need not add so many bands. If you don't want to shoot through a wall, take all but one or two bands off. Well, I have never really had a K'NEX battle, as I don't have any friends in my hometown, but I can see why fined ammo would be banned. I have never really used fin ammo, as I have never made a TR weapon, and fined ammo does not work in my BL mechs.
