Silencers

[Dark Destroyer]

need help building and distributing Silencers.
i think LavaRed might enjoy this thread.

If your not machining them out of metal, dont even try and if your in the United states i think this thread would be better in the BI forum.

here is good too.

Yea, not trying to cause problems.

I'm just saying that machining your own suppressors is extremely illegal and you will get definite prison time if you get caught with these.


On another note, I did some reading on them before and I am going to say that making these out of anything other than metal is an extremely bad idea. As much as anyone says it is dangerous to make them out anything but metal.



Also what are you looking to silence? From what Ive read it is almost impossible to suppress say a .45.

And Hopefully you already know the common misconception that just because you have a suppressor does not mean that the gun is going to be like James Bonds 9mm.


LavaRed will probably know a hell of alot more.

Again not trying to toll your thread, just some tidbits.

Ok. I'm going to start with b00m's post first. And please, b00m, don't get mad at me, because I am about to correct some of the stuff you said. If I misunderstood anything you said, I apologize beforehand.

Firstly, .45 ACP is one of the most effective calibers to suppress. Granted, it will not go James Bond silent. What you hear in Hollywood is the sound of suppressed CO2 guns. But .45 ACP, because it normally leaves the barrel at subsonic speeds, lacks a sonic crack and so is one of the less noisy, large caliber rounds. 9mm is one of the worst to suppress, because of the high speed, but it can be done. Still, the lowest sound levels I've heard out of a 9mm was with my own design at 114 dB (sound meter at the muzzle of the can). With a .45 you can bring that figure down to around, say, 105-110 dB.

Secondly, as I demonstrated, you can use PVC tubing for the body of your suppressor, although I would rather the endcaps be steel, because a nut + PVC endcap + Epoxy will suffer misalignment rather quickly.
What definitely does not need to be steel are the baffles. You can make them out of wood, plastic, or even ceramic, which would, in theory, be even better at dampening the sound and absorbing heat, than wood.
However, if you do want a suppressor that will last you a few thousand rounds, go steel. My wooden baffle one has lasted over 50 shots without showing wear. Note my first experiment in PVC failed because it never managed to hold alignment. Building an all-PVC can for anything larger than .22LR is not recommended.

Most disposable or easy-build cans are conceived for .22LR, because of the low recoil. The recoil forces from anything larger will no doubt disrupt anything which isn't steel. In fact, the only part where the big can manufacturers (the quality ones anyway) use anything other than steel is for the suppressor body, which just needs to be strong enough to resist muzzle blast pressure anyways. The other part is the blast baffle (first baffle in the stack), where exotic alloys such as inconel are frequently seen.

Speaking of the blast baffle, this is the single most important component of the baffle stack. If you have a good blast baffle design, you have a good can. The opposite applies with equal force. DO NOT, repeat, DO NOT, use anything lesser than stainless steel for this baffle (Aluminum, Titanium, Brass, Copper, etc, are to be avoided at all costs). It must also be perfectly symmetrical in all aspects. If you have an assymmetrical blast baffle, you run the severe risk of having assymmetrical gas dispersion overtaking the bullet, which in turn can cause it to tumble and experience baffle contact. This invariably destroys your suppressor.

The closer the bullet-path hole is to the diameter of your bullet, the better your can will suppress, but the more careful you will have to be in aligning your can. Normally, cans for 9mm have a 10mm wide hole. I used 15mm and it worked ok. Also, the Quality of your can's muzzle crown greatly affects how much your POI will shift. Try having a threaded muzzle crown ;) . Special tip.

Finally, note that even the best .22LR pistol can will sound as loud as a loud clap or a book dropped, so no doubt it will create a stir. A disposable suppressor may even sound as loud as a slammed door, which is about as silent as an excellent 9mm suppressor will take you.

That's all I have to say. Thank you for listening.

Any questions?

No, "here" is not good. Take it to Uncle Bob's (the thread) or Bad Ideas.
