The best knex pistol, period.

The Ultra Pistol 2 is easier to use, stronger, more reliable, faster firing, has better sights, is equally powerful, ranged, and accurate, and accepts more types of ammo than the original.

It can fire blue, yellow, red, and gray rods (yellow fires the best).

Influences
-DSman's DD-27 Assault Rifle
-Jollex's DD-27 Pistol
-KILLERK's Pistol

NOTICE: The handle is right handed. If you are left handed, build it flipped.

If you're using that metallic blue connector to keep the firing pin inside the barrel, wouldn't you need to weaken it, so that the firing pin can still slide easily?

i just figured out the most amazing thing. this gun has great power and distance already... but... take two of those long balloons that you used to blow up with that little pump when you were a little kid, you know, the ones that clowns make animals out of. snip off both sides, tie each side to the other balloon. and tadah. you got a super rubberband. this came purly out of nessessity... and it shot into the woods in my back yard with an odammo yellow rod. i just looked at amazement. my yard is at least a good 80 feet long. i had to do a second one just to make sure i wasnt dreaming XD.
