In following the instructions in this book you can make a quality silencer for your gun, pistol or rifle . This design applies also to paint ball guns and it is simple to modify it according to tables in book. It is even simple to increase the size as to diameter of main tube and the overall length of the complete silencer. When changing andmodifying the silencer it is important to change measurements of other parts accordingly. This type of silencer design has been in use for over 30 years, with good results. As an example, with ammunition under, the velocity of sound about 1087 ftp/sec or 331 m/sec. you will only hear the fall of the firing pin!, and no more than just like the sound of spitting! The good attribute of this silencer, isthat disassembly and cleaning is simple. If customers want to use this type of silencer for larger guns, with higher velocity ammunition, can modify it in size as mentioned above, and use lower velocity ammunition for better sound suppression. It is inevitable that breaking the sound barrier will cause some sound crack, when it is broken.
Here are photographs of internal parts, to give you ideaof how simple this type is, and easy to make.

Measure the bulletdiameter of your gun ! Larger calibers: The rule of drill size diameter is, drill holes in shims and front end plate, 1 mm-1.2 mm above bullet diameter.
1. After making and installing according to the drawings No.1, No.2, and No.3 ,check that there are no obstructions in bore and out through silencer. 2. Use subsonic ammunition for best results . With this Silencer there...
