Air Lock Industries Suppressor

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.

The 22 prototype is the best example of how ridiculous your technology is. Seeing it's size and numbers lined up like this is mind blowing .

Tonight's suppressor testing — shooter‑ear numbers (3 shots each unless noted).

Shooter position: inline with shooter's ear, 6" from center line.

Note: an OG (early prototype/factory example) was present; it was excluded from fair comparison in since it wasn't a production version.

22 Creed Test — 18" barrel (Hornady 62gr ELD‑VT)
- Bare muzzle: Avg = 158.13 dB(A) (shots: 158.0, 158.2, 158.2)

- TBAC Ultra 7 (30): Avg = 137.83 dB(A) (shots: 136.1, 138.8, 138.6)
- Zero Gravity 7mm: Avg = 132.10 dB(A) (shots: 133.8, 130.9, 131.6)

- Bare muzzle: 156.7 dB(A) (single reading)
- Airlock 22 Prototype: Avg = 131.37 dB(A) (shots: 132.1, 131.0, 131.0)

223 Test — 22" barrel (Hornady Black 73gr)
- AB A10 (556): Avg = 131.63 dB(A) (shots: 132.4, 131.0, 131.5)
- Airlock 22 Prototype: Avg = 127.93 dB(A) (shots: 128.9, 127.0, 127.9)

223 Test — 16" barrel (Hornady Black 73gr)
- AB A10 (556): Avg = 133.17 dB(A) (shots: 134.0, 132.3*, 133.2)
- Airlock 22 Prototype: Avg = 129.37 dB(A) (shots: 130.2, 129.2, 128.7)

Those are some impressive numbers. Makes me want yall to make a bigger can for maximum suppression for my coyote/tripod gun where I'm not concerned about weight. Is something like that possibly coming down the road??

[swavescatter]

Now thread the muzzles so you can thread the 7mm onto the 6.5mm onto the 22 can

Seriously, great work. I think all three on are on my post furlough purchase list.

 

[dreamingWest]

Have we (Rokslide) had a direct comparison between the OG6.5 and the Airlock 6.5 yet?

Thank you for sharing this.

@4th_point — Looking forward to your dissertation on this.

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.

Agree, and that's the case with any subject. This atmat clown is the poster child.

 

[HuntHarder]

Great info. Thank you for doing this. Your cans look really impressive.

 

[Ajsomp]

I mean if I did my math right - with the projected rokstok lite weight and the ZG 22 cal suppressor - I’d be sitting right at 7lbs with my 223 tikka.

I imagine the guys running the UL AR builds and UL Scopes wouldn’t mind throwing one on either

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.

Please explain exactly how these expensive sound level meters are being used improperly. Not in this thread - start a new one specifically on that topic. Not for a step by step to help manufacturers improve (that’s professional consultation). I’m asking specifically for “what the consumer needs to know.”

I’ve found many of the smarter people I’ve met are able to articulate complicated topics in a more approachable manner.

We tested it on my UL AR and it felt like a toy.

It’s crazy how the airlock silencer drives people to make personal attacks towards other forum members.

It seems like the same few individuals on every suppressor thread throwing mud at each other.

 

[Q_Sertorius]

One thing for sure is clear, these suppressors have very real potential to be awesome.

 

[JGRaider]

It seems like the same few individuals on every suppressor thread throwing mud at each other.

I'm one that loves the fact that there are more and more good ones coming to market than ever before. Great for the consumer, and great for these companies that are making them. The strong performers will survive. Nice test Dioni, I appreciate your work.

 

[Dioni A]

Thanks @JGRaider Danny did the hard part. I just brought a few guns and got to try cool stuff. I hope it's helpful. That's been what I've always loved about rokslide. You can still find useful information here from a few people who have real experience. It's unfortunate when some people derail entire threads to show everyone how much they know without adding anything useful to the conversation.

Shot the 6.5 Zero Gravity on a 16-inch bolt-action 6mm ARC tonight. All I can say is wow. Pulled the muffs off and just shot and shot until the can got so hot I had to cool it with a wet T-shirt. No issues. This can is the new reference standard in my mind.

I wonder about the temperature on that. Did it change color?

And repeated exposure to sounds in the 120s is still not a great idea.

But, as a hunting can, it does seem to hit the mark.
