Here are the Files to make a G36 out of your Dam
Aside of the printed parts you need:
G36 Shroud (i choosed the G36C, i think the others will fit too)
G36 Top Rail.
3x M4 Screws 30mm lenght
3x M4 Nuts
for the Front of the Shroud i used two M4 flat headed screws, shortened them to 22 mm and used a M4 threaded sleeve to combine them.
On the backside of the top Rail i made Slots for the M4 Nuts. I you doesn´t have metric screw, feel free to contact me and i change them.
to slide the top rail on the adapter, you have to remove the rear sight. Just remove the holding bolt, slide the Rail on the Adapter and put everything back.
