This is my entry it shot 55 feet with exellent acuracy and it had an internal mag pusher but sadly it was dropped and then went into surgery it didnt go so well so pic two happened

It doesn't shoots 55 feet... Look. The trigger is damn infront of the system. There's a lot of barrel for the shot to travel through to get out of the gun. And looking at it, it doesn't even have a far pull back. It wouldn't shoot over 35, I'd say.

Ram behind the trigger works VERY well in knex guns, VERY efficient. the gun goes like this: FRONT-TRIGGER-BULLET-RAM-BACK the ram has LOTS of room to to push the bullet.

Do you know what a FAMAS is genius?
Seriously, who do you think knows more? You, or The Mighty Zak?

Obvious answer.

The newer verion did until i destroied it. It had less barrel and a trigger behind the mag
'Version' and 'Destroyed' I think you'll find.

No, it doesn't. The pin needs room to accelerate fast before hitting the projectile. With this, its pushed right against it. This is also why when you fire a simple single shot, you don't push the ammo by the trigger, but near to where the pin comes to a stop. To get the full momentum.
Yeah, after all Force = Momentum/Time thus the smaller the time the greater the force and so a greater range an muzzle velocity.
Where did you get that equation?
Basic math/physics.
Ah, ok, I'm 2 years off for that.
Yup it is derived from:             Force = Mass x Acceleration

and because  Acceleration is:  Velocity (Distance/Time) / Time
it means that

Force=Mass x Velocity (Momentum)

Yup. When I built Ipod Killer's sniper I only got 10 feet tops because it used this system.
LMFAO!

Think a little bit more. The pin striking the bullet is MUCH less efficient. Lots of energy is wasted while the ram speeds up. Sure the ram is going much faster by the time it hits the bullet, but sudden dissipation of the energy is less efficient than a longer contact with the bullet. Even if your suggestion is more efficient, there is no way its so much more efficient that it matters what order you put them in. Also "bullet behind the trigger" setups are more accurate than a ram suddenly hitting a bullet and sending it tumbling. In light of "There's a lot of barrel for the shot to travel through to get out of the gun." The majority of knex guns have fake barrels that do not effect the bullet in any way.
Go build a TDS and a kkc, and see which one shoots further.
The TDS didn't go that far for me, only about 15 feet.
That's what he means.
I'm just supporting Raz's argument.
And I was supporting yours, lol.

When I read your comment about the TDS, I was unsure what you meant, but assumed you meant the KKC shoots much further, so my comment is to inform those that you are agreeing with Raz.
Ohhh ok.
but that takes effort. I'm not going to go as far as that to prove something. I just don't have time.
If you went to a proper school you'd realise how silly your comment is.
Notice the "be nice" policy. I do go to a proper school, and thats why I don't watn to put effort into it, I am having to stay kept up with school so I cant put time and effort into knex guns. Realy think before you post.
Do you know the laws of physics? The ram hitting the bullet at the end of the pin strike will give maximum range. You should of learned that when you were 6. Really, think before you post. P.S I was being nice.
Which law of physics would that be? Btw when I was six, I was learning what 3x4 was, most schools don't teach the laws of physics until 6'th grade. PS: Maybe they don't teach manners in proper schools, or what ever the hell a proper school is. I'm done talking with you. You don't think before you post, you just blurt out whats on your mind. People have excuses for that sort of thing when talking, because the instant you think of a reply, you say it, but when typing, some people go back and re-read to see if they made sence, or were offensive. If I said that you didn't go to a proper school, would you be upset? Lol, my "PS:" Was bigger than my post.
Go google them. In response to your "P.S" saying you were done talking to me, if you were done talking to me, why start your reply with a question? It doesn't look rhetorical.

But by what I can see, the firing pin is contained in sort of a rail and not a barrel formed by the center of connectors, so he has complete control over how far the pin can move forward, which can allow the ammo to move forward at high velocities as well, since it is accelerating at the same speed as the firing pin. Also, no need to swear about the trigger when it is almost right in front of the mag, not at the front-it reaches back. This is a good system because it separates the bullet being fired from the other bullets, decreasing friction.
Yay! One person agrees with me!

Duh... Silentassasin always overestimates....
silentassasin21 (author)  Bartboy5 years ago
what do you know
Plenty.
Math?.... Distance?....
Or shoots at a 45 degree angle.
Yup, or shoots jammy style.
Looking back, Jammy was the one who created the "Overexaggerated ranges" stereotype.
Where did that happen?
The argument between Jammy and Zak.
Don't know what one you're talking about...
But shooting Jammy style is getting fired out of a cannon and shooting the gun when you're in the air.. :P
