If you downloaded these files, you probably live 
in a dystopian country where firearms are not
available to common folk. Now you're probably 
on some sort of watchlist, so be prepared 
to deal with KGB, Gestapo and hot milfs in
your area.



Introduction

CUMFUCKER 2000 is completely DIY electrically primed
double barrel shotgun. 
It requires no firearm components, no commercial ammo 
and no suspiciously sized hardware that would be 
commonly used in improvised firearms (like 5.5, 6,
8.8 and 9mm steel tubes).
Building it requires no specific knowledge and no niche 
tools.



Parts list

-3D printer with 200x200mm or larger bed
-1kg roll of PLA+ filament
-Two 13mm ID and at least 200mm lenght seamless tubes 
(OD can be between 21-22mm, thinner tubes can be sleeved
 with plastic pipes) 
-Angle grinder or dremel
-Drill (useful but not necessary)
-Screwdriver
-Random strands of electrical wiring, cables or whatever
-Arc lighter that produces single spark. Double spark arc
lighters may work, but they introduce reliability issues.
-3mm screws of varying lenghts from 8 to 45 mm.
-3mm washers
-3mm nuts
-Epoxy glue
-Soldering iron or lighter (useful but not necessary)
-5mm screw, rod or drill bit (only one of these)
-Flat file or sandpaper
-6-10 mm OD spring, at least 25mm in lenght
-8-12 mm OD spring, at least 30mm in lenght
-Rubber band



Assembly


Assembly is explained in the pictures. Everything that is 
not specifically explained in them is either obvious or I 
forgor to add it. In this case, contact me through comments 
on Odysee, on Reddit or Discord (Shit_on_wheels).


Useful tips:

-Use rubber band to introduce some tension to the trigger.
While it's not strictly necessary, heavier trigger pull provides
extra protection against accidental discharges.

-Grip can be affixed to the frame with normal screws
or wood screws (the later should be heated up slightly
befor the screwin'). 

-Avoid getting shocked by arc lighter. While electroshocks
and cattle prods simply send some spicy electricity through 
your body, lighters outright burn the area to where spark jumps.

-Lubricate barrel locking mechanism. Slider and everything.
Thick grease works best, but even daddy's cummies will do.

-Bottom part of the trigger can be heated up and reshaped,
this helps if it somehow does not reach the switch on the
lighter.

-Lighter can be glued in place with epoxy, hot glue or 3D pen. 
It's easiest with the pen.

- Use short 3mm screws with angled heads and strands of copper wire
to turn shells into "inside out sparkplugs".
                                                             

-Always test for spark before loading shells with powder.

-Do not wire the contacts to fire both barrels at once.
Seriously.

-Do not use smokeless powder. If commercial black powder 
or BP substitutes are used, cut the recommended starting
load amount by half.

- Almost any ID pipe can be used as a barrel, shells
can be scaled up and down. Use less powder for thicker shells.

-There's a model of 15mm shell in ammunitions folder. 
This shell is slightly better than 13mm, easier to load 
and less prone to breaking. It uses 1.2-1.4mm  nail instead of 
copper wire for side electrode.
13mm barrels need to be drilled about 63mm deep with 15mm bit to 
chamber these shells. Makes sure to not go overboard with the 
amount of propellant.

- Longer shells (like the Longboi) should be filled with less powder too.
Compensate by adding more shot/heavier projectile.
