if you've ever played paint ball, you know how annoying it is, when shooting at somebody, for them to immediately know where you are. This instructable details how to make a cheep silencer for most paint ball guns. I'm not sure how well it will work on other brands of paint ball guns. (EDIT)[Disclaimer: I Have been informed that this type of silencer is illegal because it could be attached to a firearm. This instructable is for demonstration purposes only! Do not attempt to build this silencer!
Step 1: Materials
PVC piping somewhat wider then your barrel, (mine was about 2 inches wide)
PVC piping just barely bigger then your barrel.
Fiberglass insulation(get it from the celling in your basement.) BE CAREFUL, DO NOT BREATH ANY FIBERS IN, WEAR A MASK!!!! I AM NOT RESPONSIBLE FOR ANY HEALTH PROBLEMS RESULTING FROM HANDLING FIBERGLASS INSULATION!!!
Black electrical tape
Hobby/exact o knife
Step 2: Cut PVC
Hmm, guess what we will be doing in this step?
Step 3: Stuff it!
Put the smaller piece of PVC in the center of the larger one and fill all the space inside with insulation
Step 4: Add end caps
Take the now insulated PVC piece and place it on the sheet of card board, trace with pencil. do this twice for 2 end caps. Now cut along the lines until you have 2 donut shapes. add glue to the edges and put in place over smaller piece. If this is confusing, look at the picture.
Step 5: Finishing up
Now, wait for the glue to dry so that the end caps are completely attached to the bigger piece of PVC. Now, pull on the inner piece of PVC until it slides out of the tube. Cut a three inch section out of it and put it back through the cardboard end cap. This will be the front of your silencer. now take your paint ball guns barrel and the electrical tape and wrap tape around it until it firmly fits into the piece of 3in. PVC on the front. now insert from the back.
