1/2” threads?

Yes.

Picked up my 6.5ZG today. Put in some ear plugs just lightly and tried it out on the 16” 223rem bolt gun. Shot 5 with the ZG & 5 with the tbac ultra 5. The zero gravity way quieter. Next I was going to try it and my HTA chameleon
(8”x1.5”,30cal,18oz) on my 18” 6.5creed. I thought it might be close between these 2 cans before I shot but the ZG was much quieter after running 5 rounds with each on. Going to try it on the 18” 25SST tomorrow. But so far the sound reduction is impressive for such small lightweight can. More a whoosh than a crack sound.

We're going to test it on a whole pile of stuff tomorrow. I'll be out there with him. Some of the test guns
16 inch bolt action AR in 223
22 inch tikka 223
16 inch bolt action AR in 22 Arc
18 inch tikka 22 creed
20 inch tikka 22 Creed
22 inch tikka 22 Creed
Plus whatever Danny is bringing.

I have 6 other cans we may or may not test for comparison sake.
Ultra 7
OG 30
Ab a 10 30 cal
Ab a 10 5.56
PWS 5.56
JK armament

I just hope people don't nitpic everything as bad as last time I tried to help provide comparative information

Calibrated and set up the meter tonight. Three shots - 130.2 dB(A) average on a 22” 22 ARC. We’ll be doing a full test day tomorrow with more data, but initial numbers look very promising.

Just watched the video on Facebook. That suppressor looks like the perfect fit for the Howa mini 22 arc!!

 

[Ajsmith]

that’s a nice suppressor

Honestly the whole point is comparison. Just shooting it on different guns and saying I think its good doesn't give any meaningful information.

Will you be or can you meter the zg 6.5 & 7 on the 22” 223 for a comparison? I’m not sure which one i want to get for maximum suppression on a coyote rifle….

I was curious about that too.

Yeah I’ll be bringing both of those and will meter them as well.

Got out again today with the OG & Zero G. Had three bystanders weigh in this time. And you’ll all be very proud of me; I wore hearing protection the whole time haha.

Polished off a 50rnd box with each rifle. Both 6mm, both throwing 108 ELDMs at roughly 2750fps. Yup, it’s definitive. The Zero G is quieter. Not wanting to beat a dead horse, but it’s very noticeable…as far as suppressors go. It’s not like comparing a suppressed 22LR to a braked 7PRC, what I mean is it’s different enough that you don’t have to focus to notice it. It stands out while you’re shooting. I didn’t intend to do any specific testing today until about ten rounds in with each when I thought, “Wow that Airlock is quieter”.

Not writing to disparage the OG, more just to give that as a data point. I will say this, the Airlock gets hot FAST. It was a hot day down here but I caught mirage at one point after the second shot. I get that’s the trade-off for being so lightweight, so it’s not a knock against it. Just another observation. I don’t want it any heavier for its intended use.

What we need now is for Airlock to make longer versions of their suppressors for extended range sessions, coyote hunting, etc. Maximize that tech!

Pew science isn’t peer review. Not saying good or bad on it, but it isn’t “peer review” when you have hidden methodologies and standards that you won’t tell anyone.

And wasn't there that podcast that a few of us listened to and came away thinking that perhaps that guy didn't actually know as much as he claimed? ...

Which podcast ?

 

[Dobermann]

Which podcast ?

Can't recall. Maybe about a year ago? I think a couple of us posted about it here.

 

[Middle_Ridge]

Based on the performance we’re seeing with the .22, we think we can downsize the 6 a bit without compromising performance. The exact ratio is still TBD

Stoked for the lightweight 6mm!!

Stoked for the lightweight 6mm!!

I'm stocked for the 3-ounce .20-caliber version!

Pew Guy was on the EXO podcast, or whatever it's called, in the past year.

I find him annoying to listen to, and I'm not really interested in his hearing damage rating, but I can't say that I've ever heard him say anything really stupid regarding noise. Can't blame him for trying to make a buck, with his proprietary rating. In my view, no different than trying to sell cans based on undefined "tones". Both are gimmicks, right?

Well, he did say something about firearms and explosions, which is technically incorrect. There are zero explosions in standard small arms. In other words, gun powder is a propellant and not an explosive. That may not mean much to most people, even the typical Mechanical Engineer, but there is a difference. It has to due with the material response.

In contrast, I read and hear all sorts of stupid technical stuff posted on Rokslide and in podcasts. Especially about noise, drop testing, etc. We've got people buying sound level meters (SLM) and not knowing how to operate the meter or report the results. It's actually a bit embarrassing.

Anyway, I believe that Pew Guy is a licensed engineer (i.e. PE), and his background is in structural dynamics. Structural dynamics and noise analysis are not the same, but somewhat related due to the need to understand frequency content.

Here's the deal... people that specialize in noise and structural dynamics can be very weird. That stated, there are not that many real experts in these specialties. I believe that Pew Guy specializes in structures exposed to blast energy. That is a very specific field, which requires extremely high levels of technical competence. People at this technical level may not articulate findings very well to the general public.

When I was involved with vibe and acoustics, my mentor told me that there were probably less than 10 people in the US that knew how to perform our experiments and product dev. I wasn't quite sure what to make of that until I started attending international conferences where leaders in the industry and field presented their research. Everyone that I met at these conferences told me that my mentor was the best in our field, for our research area.

My career path was to be technical leader for noise and vibe for a global manufacturer. Sounds impressive, but once you get the technical competence you realize that you are surrounded by people who have no idea what they are talking about.

Here's the catch... the people that know the most are the first to admit that they are not experts. Those that are clueless, tend to talk out of their asses. For some reason, Rokslide has a lot of the latter.

Congrats, atmat.

At least you can admit it.

Strange that ZG 7mm wasn't as quiet as the ZG 6.5 both times.

Bore diameter plays a role in the Zero Gravity's ability to manage turbulence. The 7mm is quieter on 6.5 Creedmoor just not the 22 Creedmoor.
