what do u have against block trigs, huh? theyre the sturdiest and most relibale ones, and they work better than true trigs. this is revolutionary! think of all the possibilities we can do ! block triggers with wings! Block trigger on a stick! block trig alarm clocks! block triggers on block triger! the sky's the limit!

'block trigger on a stick' lol seriously

no username is right true triggers are best but block ones are a little more compact and simple, good for small spaces..........not for a machine pistol :D

yes that is true but which trigger breaks mre pieces THE TRUE TRIGGER i recently made a gun and was suprised tp see that after about 5 shots a piece broke then i made a block trigger fun and guess what

Thank you? :/

dude, be quiet. If i recall... Easy Knex Pistol This pistol is easy to build. It is powerful for it's small size. This is my first instructable. This gun shoots about 25 feet. Which is also a block trigger. You made another gun for your first and only, he made something with an immaginative idea, and got a great result!

thanks for defending me! :)

lol its okay

First off tanks roll. Also how in the world do you put a true trigger on a tank?!? (:D)

you could make it so that if it bumps something, The ram hits the thing at hi power. That would be a "bee sting " machine. It would hurt.

Don't ask me. Instructable doggie made it, but I'm pretty sure you can.
