its a gun but its a cross between a sniper rifle and a normal rifle its quite powefull with the right elastic bands can go through polestireine this is my first gun so dont be harsh.
Step 1: Barrel
make the barrel just follow the pictures make it in two parts its easier.
Step 2: The firing pin
once again simply follow the pictures
on the second pic the grey rods are bent it not because of the gun it because they old and the little bit with the blue spacers is a thing for dampening it so it doesnt destroy itself when you fire it.
on the fireing pin under the black tape is an orange rod connecting the grey rod to the slide i didnt take it all apart because i couldnt get the black tape off so youll have to look at the pic carefully for that.
Step 3: Middle section
do i even need to say follo the pics again? damn i sed it
Step 4: Backrest
this bit is so the knex doesnt dig in when you are pulling the fireing pin back
make or gather all the parts in the first pic
Step 5: Trigger
make the trigger you will need some kind of string about 30 ish cm long you have to fiddle around with it until you get the tension right depends on what string it is and how long.
Step 6: Assembly
Step 7: Add final piecies
make the green handle and clip it in like in the pic then swap the grey connector at the end of the pully for an orange one then slide apart the green connectors on the handle and slip the orange bit on the pully in also thread the string assembly through for the trigger
the last two pics are the rubber band positionings the first one is for small rubber bands and the last one is for large rubber bands simply thread it through the slot inbetween the two barrel sections. n your done
