Give a general description of the Instructableis my homemade beretta 92 fs spring airsoft silencer. I would say that the total reduction is something like 30%-40%.
Step 1: Materials
You will need the following materials and tools to complete this project.
a length of 1 inch or bigger diameter thin-wall pvc pipe
1x mini (12 oz) gatorade cap
1x 2L coke bottle cap
1x expo dry erase marker
a bit of pipe insulation
epoxy or some other wicked strong glue
a rounded file
a flat file
clamp(useful for holding stuf togeather while drying and holding stuff while sawing it in half)
Step 2: Finding the Right pipe
I found that a 1 inch diameter thin-wall pvc pipe worked fine with this gun. I would recoment that you don't make the silencer longer than the gun itself.
Step 3: Finding the right size end cap.
I found that a mini Gatorade bottle cap and a 2L coke bottle cap fit perfectly. Fust put the coke cap inside the Gatorade cap and glue them together. I used a five minute epoxy to securely hold them together. You want a very strong glue for this part. Anything less will cause the cap to fail in later steps.
Step 4: Finding an adpter for the muzzle of the gun.
I found that the orange tip had a diameter of roughly 5/8 inches. I searched around my house and found that an expo dry erase marker had the perfect diameter. I pulled out the back with a pair of needle-nose pliers. I pulled out the ink foam thing and then pulled the felt tip out of the front. I then cut the marker tip off so I had a small 5/8 inch diameter tube. i used my hacksaw to cut the tube. it's stiffer than it looks.
Step 5: Fitting the adapter to the caps
I drilled a 5/8inch hole into the caps but found that the hole wasn't big enough for the expo marker so i filed it into a rough circle untill it fit VERY TIGHTLY ONTO THE EXPO MARKER. This is very important because otherwise you will beed to glue this as well.
