Appreciate it. Folow-up: assuming disruption of the gas movement can be beneficial, is there a realistic limit to this, i.e. too much can also me a bad thing?

Might be a question already covered, if so, sorry.
Do stepped cones offer any benefit to suppressing? For a mental exercise, they would appear to offer some benefit, if only to create additional disruption of the gases.
Thanks

I think there would be benefit from ending on a shoulder, perpendicular to the bore's concenticity.

Very interesting tests and results, following along for the ride as I currently own none of the device models used. You mentioned in the linked write-up light primer strikes attributed to the Storm Lake barrel? This confused me a bit, is it possible that the barrel in question has a deeper than norm...

On an SBR form 1 I sent in back in 11, they lost my check and then denied my F1 due to non-payment (let that sink in for a sec). Since they denied the form 1 instead of putting it in a 'hold' status, when they got around to telling me about it, too late to fix the problem and send them a new check, ...

It would still be fun to have a personalized QR symbol on a magwell.

This just goes to show, you can tune a piano and you can tuna fish, but you can't tune a can!

I'm not saying this specifically is, but a lot of what they (ATF) do is mandated by law. You're best best is to write your Senator and Rep, and become active with NFA clubs and associations etc that lobby for change. Great idea though, lets take it a step further and have the ATF start a 'pre-approv...

How about a female 3-lug so you can design and mount a new-style flash hider, then hell, design a suppressor around it on a Form 1. It took longer than I thought before someone showed up with a attempt to get around the regs. The point is, intent. If you INTEND to make it a compatible mount for som...

I agree with the above poster in that I really don't think the ATF, in general, is going to bother with an individual doing a repair/replacement on his or her own F1 can provided the damaged parts are destroyed prior to the manufacture of the replacements. Also, who are lawyers in here? I was always...

That is an extremely sexy suppressor.

A part of me hopes you'll not cover it in a finish.

Man, that Titan QD looks pretty sweet color case hardened like that...gotta wonder, won't this really mess with the metals
after a little bit, specially the lighter steels?

That last one looks like it is sagging a bit, bad photo angle or is it really damaged?

One of the guys over on arfcom in the suppressor section, vendor rep from Gemtech stated he preferred to use #2 food equipment grease as his wetting grease. Thought this was interesting enough I've been looking for a local supplier for it in smaller amounts. Not sure how links to other sides are wel...

I've never seen nor do I know someone who has had a catastrophic failure of a suppressor. I don't think it is because people use 'aluminum', I think failures would be because 'they' would use the wrong kind of aluminum or use a poor design or a combination of the two. If you put crap in, you get cra...

I can't answer in detail all of your questions, but I can a couple. The distance between baffles. The first baffle is usually set back a larger amount from the muzzle as this one catches the most heat, burnt & unburnt powder and pressure. This is called the blast baffle. The remaining baffles do...

Are you looking to quiet the impact of the round in the trap, quite the discharge of the weapon into the trap, or both?

OK, what about if no SOT? just outsourcing to someone who has a lathe? is that legal?

No

Looking at the whole picture, you'll need to consider how sounds reflects from, travels through, is absorbed by and resonates in different materials as well. So not only the shape of the parts and their materials but how they are attached or fitted to one another can have a profound effect on its pe...

I'm going to take a guess and say that the 60 degree angle of the cones is a compromise. Too steep and the can becomes too long (with dB being equal), too shallow and you would need more for the same sound reduction, again making the can too long. Cone-shaped baffles in and by themselves are not the...
