Unknown OG 6.5 & Airlock Zero Gravity 6.5

You'll have to do more than just keep an eye out. You better set an alarm and have your phone in your hand when they drop. They have been selling out in less than 5 minutes when they drop

That's wild. I just found out about these. I live 5 minutes away from where GSL suppressors are made so that's what I own. Plus they have a huge veteran discount. But they are longer than I would like.

Do they announce drop day?

I was going to start a new thread but saw this one. Here are my thoughts after about 500 rounds with both the OG65 & Airlock 6.5:

The two are almost the same exact can insofar as it pertains to lightweight hunting suppressors as far as most guys will be concerned (i.e, lightweight suppressor that adds 4” to muzzle and makes it suppressed). But personally I would lean toward the OG65 after having both for a while.

As far as their physical attributes, I like the way the OG65 looks on the rifle more than the Airlock. The extra 2oz…you don’t feel it. The OG65’s slimmer diameter makes it slightly easier to keep it out of the scope’s view (as when adding a suppressor cover). The fact that it’s 8” long means I can grip it with both hands when tightening; to date the only suppressor I’ve ever had work loose was the Airlock, and several times, until I gave it the ‘ole man hands (bc it’s so short and there’s less leverage). The Airlock is just a touch worse with mirage. Only knock against the OG is that if I really leave it there for years will I find rust on the barrel later? But that’s just my OCD talking. Heck after hunting season I just shoot some Hornady One Shot up there, so meh.
All this said….looks are subjective, you can learn to tighten either down with no ill effect, and running without a cover as I do has made the diameter difference a non-issue. The only real difference in form factor is whether you have or plan to have a large enough diameter barrel where the OTB will be an issue.
The biggest difference between them is the sound.

The lower tone of the OG65 means that if I have a fast & close opportunity at an animal, it’ll be ever so slightly less harsh to my ears. On late season deer I’ve done this twice (bc I just forgot to put earbuds in).
But in such a situation it’s slight, and given that 99% of all shots fired will be with hearing protection…don’t know that this is really enough to sway a guy one way or the other.

Apart from being the shooter in hunting situations, I’ve shot over 300 rounds with both side-by-side I will say that the tone difference is noticeable. It’s not “well, I’m tone deaf so…”
Nah. It’s just that guys don’t specifically pay attention or aren’t around other shooters or don’t do drills or heck just don’t shoot much. But it’s very obvious when you’re around a lot of different shooters & suppressors.

The most specific/highest round count suppressor testing I’ve done was specifically between the Airlock & OG 6.5mm cans; what became very obvious was that from the shooter’s perspective under your earmuffs the Airlock will sound like a neat hiss and the OG65 will sound like a boom. So guys just shooting off a bench at the 100yd range will say the Airlock is better. But take the earpro off and stand 10-30yds back, the opinions sway the other way bc the OG’s lower tone suddenly becomes “way less harsh”. The overwhelming agreement was that their volume is equal but their tone sets them apart
Personally I believe the lower tone helps more with animals’ inability to locate the source of the sound…but zero data to back up the belief.

In the end…to most consumers they’re pretty much the same darn thing. Same 4” in front of the muzzle, seem to be the same volume, weight difference is negligible. But to me and everyone who helped with testing for a high number of rounds, it’s just a fact that the OG65 sounds better. That said, the determining factor between them for most consumers will likely be their barrel contour and perceived issues with OTB design.

And today I pitted the OG65 against the OG-S on a couple near-identical rifles. 6CM & 243. Buddy shot two with each, we swapped cans, repeated the test. That way the slightly different loads couldn’t be blamed for the results.

My only test was to stand 20 or so yards back without earpro for these 8 shots. Four, then about 20min later the other four. I’m not likely to delve any deeper into it, but wanted to share.

Results? I’m incredibly impressed with what they were able to accomplish with the OG-S. The tone is almost the same as the OG65, the volume very slightly louder. I think it’s the perfect can for my 6ARC (noticeably quieter than the 6CM/243). But, yes the OG65 is slightly quieter.

After spending time with the OG, Airlock 6.5, OG65, and OG-S…if I had to pick just one it would be the OG65 hands down.

I wish they would have a option to get the OG 6.5 and 6 threaded for 1/2" from the factory and avoid the adapter nonsense.

It’s just not do able with tooling. 5/8 is hard enough.

 

[Bama67]

Ok gotcha, I think I missed that earlier.

Thanks for the review. For those of you who have shot the OG 65 and Airlock 65 back to back was there any perceivable difference in recoil?

Has anyone tried to clean one of these US reflex cans? I shoot enough that I add a couple of ounces of carbon to a suppressor before too long. With a muzzle-forward suppressor with an end cap and/or hub mount it's very easy to clean out that carbon using Breakthrough suppressor cleaner. Is it possible do do this with these one-piece reflex cans?

Fill an ultrasonic with house hold CLR and let it do its thing.

Does this reduce the life or affect the cerakote?

Stainless it can discolor after awhile, titanium like our cans it’s perfectly fine. Haven’t noticed it hurting Cerakote but don’t leave it in there for multiple days etc just to be safe.

Didn’t look for it specifically so take this with a grain of salt…nope. Meaning nothing stood out. But I was mostly shooting them on 6CM type rifles. With earpro on as the shooter, the Airlock makes a really cool hiss noise that I think gives the mental impression of elongating the recoil impulse…? If that makes sense. But I doubt they’d meter different on a fancy recoil-o-mometer machine haha.

Said I wouldn’t delve any deeper…but curiosity got the better of me and a couple dudes were happy to oblige so today I did six rounds each with 6CM & 6ARC. Two then two, repeated three times.

6CM with OG65
6ARC with OG-S

The 6ARC was quieter and had a little bit better/more hollow tone. During the last test using the 243/6CM with both cans, the larger OG65 was slightly quieter. During this test with different cartridges, this time the OG-S quieter by the same amount. In both cases it isn’t a huge difference, but it’s definitive.

I stopped short of swapping cans to try them on the 6ARC bc I like to do this test back to back and the time waiting to swap cans wouldn’t give me a good enough impression to write anything about. But, for a 6ARC the OG-S is freaking awesome. It’s officially the quietest rifle I own. And given the slight difference, I’ll take “Shorter by an Inch” for 500, Alex.

Have you compared them to any full length cans? Your talk of shooting without buds has me thinking of the 2 times I’ve done that in the field with my enticer L and geniunely wondered if I should just stop caring about buds at all.

I want to gain that extra 80 fps back in can length/barrel length but I like how quiet the good big cans are

 

[Hurley88]

Oh no for the tests I’m 20-30yds back without earpro. If shooting I 100% will wear it. For that once in a blue moon rushed shot at an animal, the OG65 on a 6CM is the maximum I can take and it will still slightly ring your ears. The OG-S on the 6ARC takes that down a notch but I haven’t shot it without earpro on. That said, with any supersonic suppressed round I hope I never do.

I did compare the Airlock 6.5 to a Hyperion 9” can, I’ll look for the post bc it was a while ago.

Post in thread 'Air Lock Industries Suppressor'

Oct 29, 2025

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...

So if you could only have 1 and you had a 6creed…. Is there enough sound difference to justify the og65 or are you saving the length/weight and going 6s?
