Now i have almost finished my project with a new suppressor for the GSG5-SD. This is only a prototype, the surface will come in black anodized. And the tubes surface in glassblasted or knurled (customers choice)
Later this week i will have about 6 inch of the barrel perforated, for a better sound reduction (i hope), but i think i will work. The bullet will go a little slower, and the gases will have more time to vent into the tube.
Eventually search the youtube for some of my other videos, there are some with my new line of cans, tested on .308 .300WinMag and .338LapuaMagnum
