Knex Slugg 220 Rifle





Introduction: Knex Slugg 220 Rifle

Hey peeps. First instructable, woo. This gun has a 90-100 foot range with capped ammo. Block trig, but cool. Also has auto-lock. Its muzzle-loading but im gonna do research on making a mag to hold some rounds. Sweet gun tho.

Step 1: The Barrel

Just do what the pictures say. There is a close up view on the green connectors just count and see how many u need for that part.

2nd pic: that's a black Y shaped connector on the trigger (the orange connector to the far left. the black connector isnt hooked on to the grey rod it just looks like it is.

3rd pic: Oops! I cut it out but theres a green connector on the bottom behind the orange connectors.

Step 2: The Firing Pin

Simple. Once u connect the orange connector and the grey rod, slide a grey spacer down the grey rod, attach the yellow rod, and duct tape spacer and all on that side of the connector.

Step 3: Handle and Stock

The pictures explain alot. But make sure to add a blue rod for extra support between the two halves.

Step 4: Rounds

The gun fires capped green rods at high speed( high enough speed to give me a small red mark on my leg). All you do is take roll caps, cut around the cap you want to use so its small enough to fit onto the end of the rod. Then just use a bit of tape to tape over the cap. Simple, but awesome.
My thanks go out to kruser495 for the invention of these awesome rounds. Tyvm, dude. Heres the full instructable on how to make them.

Step 5: Rubber Bands

Sry, no pics. My web cam died just before i could take the rest of them. But anyway, for the auto-lock, just hook a rubber band on the block trigger and pull it diagonally across to the muzzle of the gun. Hook it on there to the end of the left grey rod.
For the firing mechanism, just hook 3 or four (im using three for 100ft range) rubber bands on the last notch of the firing pin connector, pull it between the two sides of the stock, pull it along the underside of the barrel, thru the two bendy rods, and hook it onto the small v shaped notch between the two free connector notches on the front green connector.

Step 6: Loading and Firing

To load the gun, just grip the yellow rod sticking off the end of the firing pin and pull the pin back until the auto lock goes off and the trigger sets. Load your capped round with the cap side entering into the barrel first. Only push the round in far enough that it is ONLY JUST concealed by the muzzle of the gun. If you ram it in the firing pin wont set the cap off. Just push the trigger and bam! The round travels 90-100ft! Dont forget to look for the shot because the blast doesnt destroy the rod!

Happy Shooting!!

how may green

23 green before the orange connectors

i like it, but what is with the curvy part on the barrel/handle?

i think youre being a bit too positive about the range... that wasnt mean, was it?

this is just simply a killerk copy with a long barrel. i also highly dout that it actually shoots 90-100ft. only the most advanced guns can shoot that far. and this is definitly not an advanced gun.

Does it also have the click bullet lock system? That would make it more powerful but still not as powerful.

90-100 foot range??? i don't beilve you, radioactive's SPEC-9 goes 60-100 feet mostly because its a slingshot gun, but this is a ram gun.

good gun but ,dude, get a better camera!

wow thats sure a far shooting gun but I don't really like the looks so I built it like a rifle and mine only shot 37 feet and 2 inches
