Airlock Zero Gravity 30

[Ajsomp]

You dont happen to have access to a ptr vent 1 or cat JL, do you? They seem to be two of the quietest cans from my research. Id be interested to see how your smaller airlock 30 compares as it seems to be punching above its weight class.

The JL is ridiculously quiet. I own one. Unless @AirlockIndustries does some crazy voodoo, I can’t expect a can half the size and weight to perform the same as the JL.

But size wise, adding the JL to the end of a rifle makes it a musket. On a 20” 6.5 PRC for reference.

I believe it was the Airlock ZG 7 that was compared to the PTR Vent 1 in the sticky at the top of the suppressor forum. No meters IIRC, but still another data point if you haven’t seen that.

I read that article. People there were saying the airlock 7 was quieter than the ptr vent 1. However, the argument could be made thr airlock 7 was quieter as it was made for the rounds being shot, while the ptr vent 1 was overbored. Hence why Id like to see how the 30 cal version performs on a 30 cal vs the ptr or cat JL.

Our 30 is quieter than our 7.

That is insane if the zg 30 ( 6" long, 1.7" diameter, 7.7 oz ) is quieter than the PTR Vent 1 ( 8.4" long, 1.75" diameter, 12.3 oz ).

For clarity, we haven’t tested the ZG 30 against the PTR Vent One yet. However, we do know our 30 is 1 dB quieter than our 7 on a 7 PRC.

We have tested the ZG30 against several other 6" suppressors, Ultra 7, Thunder Chicken, and Raptor 8 w/ 3" reflex. Based on both subjective ear testing and data from the Larson Davis 821, the ZG30 came out quieter overall. The only suppressor that came close was the Raptor.

That said, I don’t want this thread to turn into a debate over testing methods or sample rates. Silencer Summit will ultimately be the final word on performance.

How about the subjective recoil?

Well if the 30 cal airlock is quieter than the 30 cal ptr on 7mm, it'd stand to reason it'd be similar or even quieter on 30 cal too!

When will these be back in stock next? This might have to be my next suppressor.

I can vouch that the ZG 30 is 5-6db quieter than my Thunder Chicken. Compared on a 300 PRC 20" barrel, and I was blow away on how it compared, shorter, lighter and quieter...

Anyone try them on 300 blk? It would be awesome on a small bolt gun like a mini-fix. I have a cz in 300 blk I might suppress.

I plan to use one on a cva scout pistol with subs this winter. I’m a long ways away from getting to use the combo but I look forward to it.

My zero G 30 will live on my 12.5” 300blk mini fix , and maybe on my 8” mini fix too

Any one here test a Zero Gravity to an US OG 6.5?

Test what? I’ve fired both one after the other on the same rifle, with random folks from the range listening. They sound different, but it’s hard to say which, if either, is louder.

Right! That’s what I was curious about. If anyone has firsthand experience of one being quieter. Guess the overall theme is Airlock are smaller, lighter and just as quiet…but different sound.

The two companies rate them at the same decibel level.

The objective difference between them, from my perspective, is the rapid mirage on the Airlock. The OG 6.5 is better for range use, imo. And since I shoot a lot, that’s important to me.

And, the Airlock is a bit lighter, but also a bit fatter. I can see it in the bottom of my scope on 3x.

The OG 6.5 sticks out a bit less forward, but not enough to be noticeable in use.

If you asked me yesterday morning, I might have said, “get an Airlock.” This morning, I lean towards the OG 6.5.

Did something change overnight or is this just how close they are and splitting hairs?

Mostly splitting hairs.

Edit - if I ever have an objective reason to recommend one over the other, I will put it out there.

Is the mirage seen so soon because of a bare can vs one with cover?

No, I have LS Wild covers on both of them. From what I have read here, Airlock is a higher turbulence design that captures more gas. I am not an expert in suppressor design, haven’t cut one open, and can’t validate that. But since I have also heard that from Danny, I trust it is true.

Being thinner and lighter, it also appears to cool down faster, but shooting 10-shot strings can be challenging with it. I am not knocking it. Just pointing out something that I have observed over hundreds of rounds through each suppressor.
