K'nex Gun Terminology

Just a friendly little guide to familiarize yourself with K'nex terminology.

If you have any complaints or modifications, please pm me and I'll fix it accordingly.

Step 1: Components and Devices

Rod- The long skinny pieces.

Connectors- The pieces with holes (usually) in the middle that K'nex pieces can attach to.

Rings- Rings that are just holes, usually space fillers that fit on a rod. Usually come in the half-a-connector width blue rings.

Tan Clip... Things- I don't know what they're called. Used for wheels and connectors from spinning on a rod.

Exotic Pieces- Other pieces, like rare or uncommon K'nex pieces or foreign objects like springs.

Firing Pin/Ramrod- The rod which hits the projectile, transferring kinetic energy into said projectile, propelling it through the air. Usually propelled by a rubber band.

Barrel- The section in which the ramrod hits the ammo, made usually by clipping many connectors on to a rod.

Block trigger- A trigger in which a K'nex piece blocks the hammer or ramrod. Usually hit perpendicular to the gun.

True Trigger- A trigger pressed like a normal gun instead of sideways.

Hopper/Magazine- A sort of container which uses gravity to put ammunition into the gun without manually sticking the projectile into the gun. Usually holds rods.

Stock- Like on a real gun, a stock protrudes from the back of a gun and can rest in the armpit of the user or on the shoulder. Used for stability.

Step 2: Gun Varieties

Single-Shot - Usually fires on shot, then ammunition must be placed in the barrel and the ramrod must be re-cocked.

Bolt Action- A Single-Shot with a hopper. All you have to do is re-cock the ramrod and ammunition will slide into the barrel do to gravity. Sometimes called Semi-Auto.

Full-Auto/Machine Gun- A large chain or wheel of single shots that uses a motor to quickly rotate each individual shot in to an area where they will fire.

Pump Action- A gun that is re-cocked by a sort of pump in front of the trigger. Usually a shotgun
or a rifle.

Shotgun- "Shotguns" In real life are supposed to shoot many projectiles inaccurately a short range, but in the world of K'nex it may mean a short-ranged (but possibly powerful) gun. Often Pump Action

Sniper- Usually a single shot concentrated mainly on range, power, and accuracy. May have a hopper and usually has some sort of "scope" or hole to look through to help with aim.

    Semi auto guns use energy from the fired round to operate the mechanism;  When you fire a double action gun, pulling the trigger cocks the mechanism, then it fires.

    semi-auto is when you DON'T have to reload after every shot.

    change your link to a pump action gun the old one was removed

    ...and the firing pin is technically only used to ignite the gunpowder in the bullet and not actually push the projectile down the barrel. I don't think there really is a term for the part and function that we're looking for here. The closest is a cross-bow or spear-gun, and they don't have a rod that transfers the energy to a projectile, the string is directly in contact with it.

    To ME, it doesn't matter WHAT the parts are called just as long as the manufacturer knows what it's supposed to do. I think that"flamin_idot_dude" did a great job.
