Unknown suppressors OG testing

[thinhorn_AK]

Differing opinions based on evidence are excellent and often lead to better outcomes, but relying on subjective feelings or unproven beliefs as evidence is not adequate.

Nothing I’m saying is subjective, it’s a fact. The OG does buy you a bit of overall length. It’s also louder and heavier than some of its competitors.

Nothing about that statement is subjective.

What do you mean “the same suppression” the example I’m using is my dead air nomad ti, in its factory form it adds 6.25” to the length of the rifle. The OG adds 5” to the length of the rifle. The nomad ti xc is quieter and lighter. And only 1.25” longer. For some people that might be worth it and that’s fine. I’d personally take a reaper over an OG.

The OG adds 4” exactly to the length of the rifle. It 4” in front of muzzle, and 4” behind. So 2.25” shorter. Again- over 30% shorter.

The OG only adds 4” to rifle length.

Ok fine, I still stand by what I said. If 2” is worth it to you then the OG is a great choice.

My point the whole time is that the only thing the OG does better than others is being shorter. That seems to come at the cost of weight and suppression.

Always a compromise, like the ultra 5, it’s light and short which comes at the expense of suppression, it’s also a gimmick.

I will post all of the results from today in a full thread, however it will take me a couple of days.

Were you able to get the meter to measure A-weighting and Z-weighting simultaneously?

Z-weighting is going to be of more interest for the technical crowd. Just remember Z for Zero or unweighted. Or unmolested.

I don't see value in using A-weighting, unless a comparison is needed for legacy product/data. I know some still use it, which is fine as long as it's clearly stated as dB(A) but it can have an affect on the reported values (lower than Z, but never higher).

For reference, see how Z has minimal impact to the data compared to A, with C in between. The X-axis is log frequency. Y-axis is the weighting.

See how A whacks the levels down, below ~1000 Hz?

Noise geeks want the unmolested data, or unweighted with Z, if possible. Or the raw sound files which can be post processed with any weight applied.

No I did not get both. And I am unlikely to. I’m not nerding out on this- it is simply a comparison to show side by side with each can. The eval for the cans is more than the sound meter.

Ok, this seems tough for you to understand. Try to follow along.

He got a sound reading from a silencer….ok. Then they added volume to the silencer and it got quieter. This would happen on any silencer, add volume, it will get quieter, take volume away, it gets louder.

I’ll say it again though, the gimmick is that that over the barrel design, isn’t quieter than a silencer of equal size, it’s not lighter than a can of equal size and it IS louder.

So, if you are willing to use a heavier, louder silencer so that you save an inch or so in overall rifle length, then the OG is a great choice.

I agree with you that an OTB is likely to be noisier than a muzzle forward can; they are two different designs. I suspect someone smarter than me will probably build one next week. My OG is the lightest can I have, and yes, it's 5+oz heavier than an AL, but I am not concerned about 5oz's. As far as noise levels, this is one area where everyone's individual hearing, along with the environmental factors, comes into play. For me, it's acceptable, and the videos seem to support what was advertised. I want the shortest hearing-safe suppressor, regardless of who makes it. If someone comes up with a 2"-3" can that's hearing safe, I would buy it, but for now the OG is the one that goes with me in the woods.

I’m mostly just trying to figure what all the hype is about and if it’s something that would be worth it to me. Of the bunch of silencers I have, 2 of them are garbage (banish 30, scythe), I don’t want to buy something that I’d regret. The airlock seems impressive, so does the reaper.

When I go deer hunting down in southeast Alaska it’s thick as hell, but I havnt really had a problem with 18” barrels with 6-7” silencers, I don’t know how much of a difference of 2” would make. I can say for sure that when my rifle had a 22” barrel and I was using the banish 30 in the 9” configuration, that was straight up BS trying to get through the alders.

I think I need the Sound Measurement for the Dummies book, maybe then I will understand some part of this. No guarantee, though.

I get it, I have similar buck brush to deal with, and I hate a barrel over 18". The AL is very interesting, and as fast as things keep getting better, I can only guess what's coming.

Yup it’s amazing the things they are coming out with. I didn’t think it could get much better than the scythe when I first got it.
