Do you have a schematic of that ? I don't get how the conical washers will hold themselves inside the tube, nor what I will close it with.whiterussian1974 wrote:The 2" ID/2.125" OD tube is the container. The conical washers are the baffles. If you port the barrel, you won't need the guide rods. You simply mount Grade 5 Titanium or 304 Stainless, or even 6061-T6 Aluminum Seamless Tubing. (Make sure that "seamless" isn't just edges rolled together to join them. That creates a weak seam that will split under pressure.)
If you use the ported barrel, the purpose of the baffles is to trap the higher pressures at the earlier compartments so that each stage has lower pressure gas to expand. This is called "dwell." Dwell allows the lower pressure end gasses to vent before the early sections dump their gas pockets back into the bore for venting to atmosphere. This "smooths" the exhaust to lower pressure over longer time resulting in less peak sound generated. It sounds more like a hiss than a bark w .22lr, but 12ga has far higher volume of gas to release.
Barrels alone cost half the weapon so I won't modify one, I'm trying to same money here or indeed I would have bought the salvo which seems to be the only thing available.
I'm also worried as to how to fix the silencer to the barrel since all 3 of my shotguns (Winchester SXP, Beretta 302, Baikal MP155) have that long cooling bar on the top and are not borred except one on the inside to receive chokes.
For your information I don't live in the USA but in France, here to make or buy gun accessories/parts you need the same authorisation as the gun it goes on. For SA and pump shotguns (which are limited in capacity) you only need a hunting licence or join a sport shooting club.
But home defence is badly seen. In France you're either a sport shooter / hunter or a dangerous man with weapons. There is no place to go to practice shooting with weapons that are not sport or hunting related, such as SA and pump shotguns. So you have to do it at home, or wherever you can but it's very noisy.
And mass produced silencers for shotguns, well they are already scarce in your country so imagine here.
