I had a look at the accessories for my airsoft rifle .
It was quite an eye opener.
A silencer and bi-pod would cost more than the rifle.
So I made my own for no cost. and it works pretty well :-)

Step 1: PVC Pipe

I cut about 6" of 1 1/4" PVC Pipe.
and smoothed the edges with sand paper.

Step 2: Top and Tail

Picture of Top and Tail
The front end is a 1 1/4" nylon washer and the gun end is an end cap from a roller blind.
(This had to be drilled through)

Step 3: The Inside

The tube is filled with dough nuts of packing foam,
I cut out about 150 of these.
To speed the job up I used a couple of sharp pipes to cut these out.

Step 4: The End Result

Picture of The End Result
After sealing the ends with glue, I coloured the silencer with a marker pen, (I will use black spray paint some time later).
The silencer was mounted to the gun with a silencer adapter.
It was screwed on tight to create an internal thread.

I'm gonna come out as a party pooper to most people, but you have to be very careful "building" suppressors(silencer is a misnomer, no firearm can truly be "silenced"), even for airsoft, and especially if it is built to actually muffle the report of your airsoft replica.

The US Federal government has very strict laws regarding suppressors, so that if your "airsoft silencer" can be connected to a real firearm, and reduces its audible report by at least 1dB, it is highly illegal without the $400 Federal tax stamp. Even if it doesn't work at all, I doubt you want to get into that legal mess.

If you really your airsoft "replica"(I hate this term, just my opinion), make it a straight tube on the inside, so that it is only an inner barrel extension. If it is already so(I couldn't tell from the 'ible), or you are from a country that has more lax laws on suppressors, disregard all this!
