Air Lock Industries Suppressor

Wanted to do an objective test but again this was just a quick curiosity more than anything really controlled. And as a disclaimer, I have no dog in this. I’m not affiliated with any of the suppressor companies, don’t have any loyalty to any of them, don’t have any animosity towards any of them. Just want to share today’s experience.

Got to the range, asked a guy on staff to lend me his ears, and got started. He stood about 10-15yds behind me and didn’t wear earpro. Wish I could’ve had more bystanders but as cold & windy as it was, nobody else was there.

First shots were under the covered shooting area. Metal roof, concrete floor. Did two with the Otter Creek then two with the OG 30cal. Let them cool (didn’t take long, cold & windy out) then did it again.

Guy on staff said the Otter Creek was definitely quieter than the OG. As the shooter with earpro on, I agreed. Though I noticed the tone difference, which I’ll bring up later. He said that he wouldn’t want to shoot the louder one off their PRS barricade next to the RO shack bc it would probably ring his ears through earmuffs.

I told him to try and place this next one as either more similar to the first or the second suppressor. Then shot two with the Airlock.

Surprisingly, he said the Airlock was much closer to the Otter Creek than to the OG. I thought he’d say it was somewhere in the middle or give me a vague/confused answer, but he was very confident in his answer. Said it wasn’t quite as good but that it was very much like the Hydrogen-L. Again as the shooter and wearing earpro, I kind of agreed. I was trusting him more than me bc he didn’t have earmuffs and was paying attention only to the noise, but yeah it sounded like a slightly louder version of the Hydrogen-L to my ears.

He had to get back to work, but I wanted to repeat the test away from solid surfaces. I moved out to the open, away from everything and on a hill (was an empty space in a long array of PRS obstacles). But first…I just had to see if a 9” suppressor would ring my bell without earpro. I wanted more time between the only two shots I’d do today without earpro (yes at the end I shot the Airlock), and have never shot a large can without wearing hearing protection.

DISCLAIMER: yes it’s dumb to do this. No, don’t try this at home. An analogy was made that it’s akin to testing helmets by running into a brick wall wearing them…but in that case I’d put the helmet on a bowling ball and swing it into the wall using a rope. I don’t have any such similar way to test a suppressor. I’m not going to make a habit of this (he says while doing it for the third time), I just personally want to know whether it will ring my bell if I were to do that in the field. I’m still going to use earpro in the field 99% of the time, but one of the key benefits to me of hunting with a suppressor is the ability to make a fast shot without fumbling for earpro. I have tinnitus and earpro has cost me shot opportunities bc I absolutely will NOT shoot at an animal without it. The OG rings my bell and therefore loses one of the main benefits for me. So here I had the opportunity to try a large suppressor and just see if every suppressor would ring my bell. If it did, ok then earpro every time it is, lost opportunities & all. If not…well then hallelujah.

You were answering a question directed at people who have used both suppressors. You haven’t used both suppressors.

All you should do in a circumstance like that is attempt to be objective. Until these suppressors are tested under the same circumstances, it’s impossible to know which one is really quieter. But arguing that a can whose designer rates at 129.5 SE dBA is quieter than another can whose designer rates at 127 - and which you have never even heard - is just a bit ludicrous. That doesn’t even rate “listen to my cell phone recording” level of worthwhile.

I like Airlock as a company. Their design process seems solid. I appreciate their goals. They are very responsive and open. My interactions with Danny have been great. The EXO interview was very informative and promising. I am looking forward to learning more about the products and hopefully will get my hands on one before New Years. But until I have some basis for subjective opinions, I will stick to published facts. And, as mentioned, I really look forward to seeing objective verification of each published sound rating. Our ears are not the best tools for that job.
You haven't used both either have you?

So I fired one round out of the Otter Creek…it didn’t ring my ears at all. Not even later on in the day (which is the reason I waited to post). Usually my tinnitus will ramp up and stay more annoying after exposure to sounds that don’t immediately aggravate me. But not so today.

I put the earpro back on to continue testing. Shot two with the OG 30cal then two with the Otter Creek. Let them both cool, then did it again.
Again, the Otter Creek was definitely quieter than the OG. Then I shot two with the Airlock. And again it seemed much much closer to the Hydrogen-L than to the OG.

Well…no guts no glory. Would the Airlock make me say that I’d never ever shoot it without earpro? I decided to take care of what I could from the phone (again busy day), drove off to get some food at their clubhouse, and answered emails while I ate. After about a half hour I went back for the final shot.

With no earpro, I shot one round out of the Airlock. It did not ring my ears! Happy day.

Let’s talk tone. Throughout these shots it was very consistent. The OG had more of a boom, while the Hydrogen-L was a very sharp crack. I didn’t like the sharp crack at all. The Airlock is like a hiss; it’s definitely more toward the Hydrogen-L, but softer. Not a deep boom but not a sharp crack either. Closer to the normal sharp crack though. But smoothed out and less annoying.

That’s all for now, once I take it home I can comment more on balance/weight, whether it’s obtrusive through the scope, all the finer details. But so far I’m very pleased. I don’t know how the Otter Creek Hydrogen-L stacks up in the market either; it’s just what they suggested when I asked for their best.

I’ll say this though. I walked away very impressed by the Airlock 6.5

The OCL Hydrogen L measured 123.68 SE dBA at the TBAC summit. That’s pretty close to as quiet as .30 caliber suppressors get with supersonic .308. One other one measured 122.08.

I am glad to hear that you are happy with your purchase. For your sake, I hope you will take your own advice so you can continue to enjoy the hearing you have going forward.

Thank you for the report, Hurley.

Man I’m glad you found a silencer that you’re happy with , Thanks for the write up !

It’s also almost double the weight of the airlock. Mine is 14oz with a DT mount. It’s also a long can. Longer and heavier than a DT AB 10 stack, about the same weight with the reflex. The air lock really does sound interesting, but I already have plenty of 6.5/30 cal cans. I want one in 35/45 cal as that’s what I have to use for hunting.
