Air Lock Industries Suppressor

[AZ_Hunter]

Unless the Airlock is totally different from every other suppressor in this regard, it won’t increase velocity.

Overwhelming majority of Scythe explosions result in no injury to the shooter. Having said that, the chance is there. I know of 2 people who had different suppressors that failed, that resulted in injury. 1 of them was pretty serious, the other broken clavicle and got scoped pretty good. I wish we could figure out why the Scythe is failing. Seems to be no real consistency in failures imo. I have over 1000 rds thru mine and it still won't let go. . I expect it to, just not sure when.

Aren’t the welds failing?

Hey fellas. The videos posted today on Airlocks IG were of my 12yo son shooting the Airlock 6.5ZG and my Scythe Ti back to back out of a Seekins Element 6CM. I live in Boise and DMd Danny and he was nice enough to meet us at the range this morning. He seems like a great dude and very passionate about creating high performance, low weight suppressors.

I own a Scythe and that’s it. I have buddies with TBAC U7, Omega 30, and Banish Backcountry, but that’s the extent of my suppressor experience.

We only put 3 rounds through the Airlock, but I was surely impressed by the can that is barely bigger than a 8oz soda can, and weighs less than 6oz. The overall volume was similar to my ears, but the tone of the Airlock created more of a “whooosh” than a “crack” and sounded more pleasant. We did not do any measuring with dB meter or anything, just the Mk1 eardrum.

I will say that the can heated up quickly after 3 rounds of 108ELDM 6CM. It seemed hotter than the Scythe after same round count. Had I thought of it, I would have brought a IR thermometer. Danny did say they put 60 rounds of 6.5PRC through it as quickly as they could and it turned blue but had no damage. He did show me that can in person.

I’m very close to placing an order. Like most everyone else, I am wavering between the Airlock and the newly announced OG 6.5. I will probably continue to train with my Scythe, hoping it doesn’t blow up on me and use the Airlock or OG as dedicated hunting can.

I am curious from anyone who has experienced a Scythe or other failure…has anyone been badly injured or does typically parts and pieces move down range from the muzzle? I may have to be more cognizant or who is shooting or spotting next to me and brief that as an avoidance area.

In the Scythe failure thread, a kid got scoped real bad cutting his eye brow enough to require glue. That is caused from excess recoil of the can launching down range (like a rifle grenade). So far, that’s the only injury I know of with the scythe. But I have experienced another Ti can popping (literally my first design and build) and that had a piece of the can hit my buddy (the shooter) in the face. Nothing serious, but a learning lesson… specifically in that case the importance of blast chamber size and wall thickness.

Yeah, with no rhyme or reason. Some guys get 1000's of rounds out of them, some get 20. The "uncorking" pressure they spoke of on the podcast made a lot of sense to me the other day. Basically saying a 6 creedmoor can be harder on a can than a 30-06.

Once our patent is approved (its currently pending), I’ll be able to share more details, but here’s the short version:
For most suppressor companies, the traditional approach has been to stack more baffles and add more volume. That’s been the conventional method for 99% of the industry when it comes to reducing sound. Our design takes a different path. Instead of relying solely on volume, our suppressor creates significant turbulence right from the start, and that turbulence makes each baffle work more effectively.


Another key factor is bore diameter. While it may not have a major impact on some suppressors, it plays a critical role in ours. A smaller aperture slows the transfer turbulent gases from baffle to baffle, improving efficiency and overall performance.


That’s about as specific as I can get for now, but it’s very clear in our testing. The exit velocity shown in our videos demonstrates that our suppressor is doing more work per square inch than almost anything else on the market. Even after shooting side by side with a Scythe today, the difference in exit pressure was obvious.

Thanks for sharing that info. Looking forward to see what else you come up with.

I thought that was only with semi autos? I thought the suppressor lowed your velocity?

Most see an increase that I’ve tried.

Do you have a can and chrony? Go shoot with can on and can off and measure speed.

Freebore boost occurs because the propellant gas is still acting on the bullet as it passes through the can. The gas is slowing down (thats the objective of a can) but the vessel is pressurized and there is no friction from rifling on the bullet.

There are a lot of variables that affect how much, it could be zero theoretically, but I have always seen 25ish fps on the low side to as much as 50ish just going off memory.

Can anyone say I S B here?

I do not. Ill have to do some backwards math at known distances to see if I can calculate it out.

Thanks for the explanation.

have a chrono and have shot various cans/cartridge combos.

10-25fps is normal with vs without. All the way down to subsonics in my experience.

What sample sizes?

Small and un recorded but there. If I had to guess multiple 10-20 round samplings using a Garmin and magneto speed over last 5 years. Probably 500 shots total.

I wasn’t doing it as a test, just what I’ve observed in general.

I just wonder, because some of the factory ammo I shoot has velocity spreads such that 10-25 FPS wouldn’t even be noticeable. And I have never seen higher velocity from the same ammo lot in my 18” 6.5 Grendel CZ with 6” Scythe versus the 24” 6.5 Grendel CZ without a suppressor.
