Unknown suppressors OG testing

[Presswood_936]

If that’s truly an identical setup and recording, which it appears to be, the airlock sounds incredible.

Everything is identical , I have the uncut 2:30 minutes video if anybody wants it .

The airlock is in a different league of suppression

I’ll for sure be adding an Airlock come Jan 1.

Also here is a video comparing the OG to another new silencer , the Zero G from Airlock industries . It’s half the weight and only adds an extra 1/4” compared to the OG .

I saw a post about the Airlock a couple weeks ago and thought their claim was obnoxiously bold based on the testing and results reported by US. This is wild, thanks for the comparison!!

Pretty sure I'm gonna pick up an OG or OG 6.5 for a 16.5" barrel. However, its a 0.75 taperless contour. It actually measures 0.76ish (cerakoted)... will the OG/OG 6.5 fit on it? Spec says 0.75 OD barrels. Probably splitting hairs but didn't want to drop $1k and find out it doesnt fit.

Yes, it will fit.

The Airlock sounds great!

I'd say... Hard to put too much merit into video recordings but the few instances of initial feedback I've come across on the Airlock have been positive..

I know there has been some shade thrown it's way here on Rokslide given (the perception) of Airlock making unrealistic/unachievable claims on the specs, but between their daily comparison videos on their social media accounts, and some of the initial feedback such as @Presswood_936's above, I'm starting to get intrigued..

A random video of a suppressor gives me zero data.

A comparison between two actually gives a good bit of info. The airlock was obviously quieter in the video under the same conditions.

Agreed. We can't use most video recordings to determine sound levels, but back-to-back comparisons between different designs on the same host plus anecdotal reports can still be useful.

To Airlock's credit, the company has shown the sound level meter (SLM) used which is appropriate for gunfire measurements. Other companies seem to omit how the measurements are being made.

And shoutout to @Presswood_936 for editing the video to show the back-to-back comparison! Good job, man! It makes the audio comparison easier, plus notice the difference in gas pattern. It's not hi-speed video but you can still see the difference in venting.

PS - there's a thread for Airlock here, and maybe we should take the Airlock comments over there and not derail the OG thread:

What’s the general vibe of OG owners on here with the new OG 6.5 undercutting it spec wise much more quickly than a normal product cycle? Has anyone inquired of US if they can do anything for all the OG buyers?

Probably a bit optimistic but how about an OG 6.5 at cost (if wanted) for everyone who ran out and bought the OG for their 223/6mm/6.5mm only to see it get “way better” (their words not mine, see below from their website) just as they are starting to get to use them? Not trying to stir the pot, just curious what the sentiment is.

US’s description of the OG 6.5 on their website has me feeling for all those who bought the OG (see picture below). Atleast the majority of which I would assume bought them to run on 223, 6mm, and/or 6.5mm.. heck I guess 7mm too per their podcast..

“Way better”…

Maybe an unpopular opinion here, but US owes absolutely nothing to OG buyers. It was not marketed as being super quiet. It was marketed as being hearing safe and extremely tough. It is both of those things. For anyone to imply that US owes people cans at cost because further product development has led to a “better” solution, is absolutely unreasonable. I have no affiliation with US. The reason I put “better” in parentheses, is because it’s only better in certain ways. It’s “better” for 6.5mm and smaller calibers. It’s “better” because it’s lighter, but that also means it’s not as tough. It’s still plenty tough, but the OG handles 300 RUM, and stood up to a 33XC.

If current OG owners are now unhappy, could it not be assumed that they didn’t know what they really wanted? If they wanted it to be quieter and lighter, then why did they purchase the first can launched by a new company?

The OG was marketed as a 30 cal can that can be used for everything, and that’s the truth. The OG 6.5 might be better for some hunters, but the OG is in reality a harsh duty can.

For the record, I’m hoping they release an OG 6mm

Fair enough. To be clear, I don’t fault US for this and i don’t think it would impact my decision to potentially purchase a can from them in the future. The reality is they stuck their neck out a bit, with good intentions, and are learning and refining their philosophy and approach on the fly, as all startups do.

However, would it still suck to have just bought an OG only to now have the OG 6.5 available that in their own words performs “way better”? Yes, especially considering the reality is that likely 75% + of their buyers never planned putting this on anything bigger than a 6.5mm..

That said, would it suck to have just bought an OG only to now have the OG 6.5 available? Absolutely yes... I think US’s intentions are for the best but man it has to feel like a little bit of a gut punch as I would imagine 75% plus (if not way more) of their buyers never planned putting this on anything bigger than a 6.5mm..

Sure, it would be frustrating if I were in that position. But, if you sit around waiting on things, you’ll never have anything.

To my point, when you purchase the first suppressor by a brand new company, you are taking that very risk. Development is going to take place. Better things will come along. This one just happened to be an unplanned happy accident, and they decided to offer it. At the end of the day, make sure you are satisfied with what a purchase will provide you with.

I have shot a lot of suppressed rounds, and I believe the tone generated by a can's design does make a difference downrange, which is why I was drawn to the OG. As an owner of other OTB cans in 223 and 30 cal, I can say that I didn't buy into what US was claiming. When I shoot my 30cal can on my 223 and switch back to the 223 can, I can hear a difference. Is it enough to be concerned with no.
If US had said they were going to make an OG6.5, I would have waited and bought it instead, but I have been happy with my OG.
I might buy the new OG6.5, but I want to see the actual numbers and hear it for myself at the shop first.

I just wish my 30 cal OG was quieter . I’m pretty let down with the performance.

The OG is a very durable can that will work on any .30 caliber and below cartridge. That’s what it is and that cannot be said of the OG 6.5 or any other 6.5 suppressor. I cannot use an OG 6.5 or any other 6.5mm suppressor on a .270, 7mm, or .30 caliber. Yes, most users here might only use it on a 6.5mm or 6mm, but, as a matter of cost:benefit, to me it makes no “real” difference.

The advice I have seen and heard is that it doesn’t make enough difference to limit yourself by purchasing a smaller caliber can. And I am still inclined to agree with that as a measure of economy.

A hunter with 3-5 rifles can get a lot of performance out of a single .30 caliber centerfire rifle can. Most of the market has been built around that premise. Some manufacturers offer smaller end caps as a way of selling extras to consumers. But if you own a .243, .257, .264, .284, and .308 (as I do), do you want to buy five $1200 suppressors or one? Or buy $1000 worth of extra end caps?

If you have one 6.5mm rifle - or all your rifles are below 6.5 - then by all means get a 6.5mm can.

A normal human ear can tell that one sound is 2-3 decibels louder in a head-to-head test, but does that matter once you are below 140? I don’t think so. As I interpret the OSHA guidance, you want to get the sound impulse below 140 to avoid permanent hearing damage from a single exposure. But, for sounds above 120 db, you need to limit exposure to once every 15 minutes (according to OSHA). The sonic crack is in the 120s. So, trying to get the gas expansion sounds down below the sonic crack is a waste of time, weight, and length (unless you are shooting subsonic loads).

If you think that it is “safe” to shoot multiple shots without hearing protection from your rifle because it rates a 127 dBA, you are just flat wrong. It is marginally more safe than shooting multiple shots at 130, but not enough to make a difference. Maybe you can shoot one shot every 14:45 seconds instead of 15:00 minutes? I am just making up those numbers to make a point. To protect your hearing for more than one shot every 15 minutes or so, you need to wear hearing protection in addition to using the suppressor. And that is true whether it measures 133, 130, 127, etc.

The suppressor’s job is to get the sound impulse from the gas expansion for a single exposure below 140. It is not to “sound better” to a subjective set of unprotected ears than another suppressor.

If you are disappointed with the OG because it sounds louder than an alternative in a head to head test, then that is your prerogative, but you are being disappointed by something that does not matter. And, if you insist on head-to-head comparisons, your OG or whatever will also sound worse than an AB Raptor 10 with 5” reflex. But, as I have demonstrated above, it doesn’t matter.

As I have been selling off some of my rifles - older collectibles that cannot be suppressed - I have come around to a situation where I have multiple suppressors. But I got there only because the Scythe Ti, which was supposed to be the “only suppressor I would need” turned out to be unsafe. And I would much rather own one OG than one Scythe Ti.

The OG works well enough for me. The length is more important to me but now we have options for shorter suppressors. If the airlock and/or the 6.5 sound better to me then the OG will be moved to something that I don’t shoot as much. Would I swap the OG for the OG 6.5 based on the manufacturer’s description? Yea….lol. I’m a big boy they offered a new product and I tried one. They were very good to deal with. Life is too short for me to get butt hurt over them releasing a new and improved version a few months later.
