Step 1: Stuff you'l need
highlighter / maker pen
can of spray pain (any colour)
any bits that can make it look more detailed.
Step 3: Step 2
paint the colour of your choice (I chose silver, only metallic paint I had)
(I also added part of a barrel from a cheap old bb gun to make the end hole smaller and better looking :))
*ALSO MAKE SURE IT FITS TO THE GUN BEFORE PAINT!!*
Step 4: Step 3
after these finishing touches your silencer should be finished.
