Unknown suppressors OG testing

[HuntHarder]

At almost twice the price of the evo, it better sound better. Similar weights just no Otb.

OG sounds a little louder than than my ab raptor 6 with a 3" reflex. But the "tone" is slightly lower. Polo 30 seems a little quieter as well but way different tone.

All on a 16" 6 arc and under a roof for what that's worth.

No sparking as far as I could tell.

Roof pretty much negates all perceived sound imo.

For sure, just relative comparison

We have a group of guys that go on an annual rockchuck safari every year which lasts a week. (This was our 24th year.) We've got several ranches that let us hunt and we can shoot out to about 2000 yards or so with most shots ranging in the 400 to 800 yards. This was a perfect chance to test the prototype OG. Between that event and several since then, I've got about 400 rounds through it with a 6 creedmoor.
Now, none of us are suppressor experts by any means and we're all over 60 so none of us can hear worth a shit anyway.
We did an impromptu test with a cell phone decibel meter app and we shot all the suppressors side by side 10 seconds apart with the sound measured standing behind the shooter on their shooting side.
The other cans there were all 30 caliber and they included:
-----sig sauer x 3
-----dead air
-----EA
-----Banish backcountry
-----OG

We were all shooting 6.5 creeds, 6 creeds, 6.5 Swede, 223, so no big calibers

Decibels were from 104 to 112 with this very very NON SCIENTIFIC CHEESY METHOD.
It was interesting to hear the difference between them and the OG definitely has a different sound from the others. Not really sure how to describe it but it's good and it just carries very well. Love the balance.

Randy,

Chuck shoot looks like a hoot. Get any sage rats over there? I'm convinced the chucks are smarter than the sage rats!

Regarding the cellphone apps, there are two issues using them for gunfire:

1. One is the frequency response of the internal mic and/or accessory mics. Think about old school hi-fi equalizers with sliders for setting up the sound the way you like - with the mics used with phones it likely misses some frequency bands, if that makes any sense as an analogy.

2. The sample rate is too low to catch the very peak sound decibel level.

That stated, an app can still be useful for other sound measurements. NIOSH had/has an app for Apple phones that is really good. I use Android but attended one of their scientific presentations when they were releasing it (for automotive related uses). Definitely a useful tool.

Was the 6 arc a bolt gun or gasser?

Those are all fair points. I agree cell phone audio is not ideal but it’s all I’ve got. I can try to shoot it to compare on 6.5C or 308 next time I’m out if you like. The reason I only shot it on 223 is I honestly don’t like it on anything bigger without wearing ear pro because it’s got a very harsh crack that I find painful. So for the range with ear pro it’s okay but I didn’t like using it to hunt with my 6.5C.

I think the simple answer is if you like your harvester Evo, especially on larger rifles, then you will LOVE the OG since it’s better in every way. Lighter, quieter, better balance, less length in front of muzzle.

I appreciate the comparison! No need to go through the trouble of making a new vid for me. I'm currently torn between the LPM Anthem S2 and the OG, leaning toward the OG.

What’s the rifle and intended purpose? I just looked up the LPM and that’s a very different suppressor than the OG with a very different use case.

 

[WhoGarrDen]

What’s the rifle and intended purpose?

18" 7mm-08 and 22" 243. Lots of days with 100rds/day load dev and practice at the ranges, and still hunting / blind hunting.

The numbers you get from a cell phone or other noise meter not designed for gunshots are basically meaningless. The sound event for gunfire is 3 to 5 milliseconds and the sample speed is far too low to capture it. 15 years ago when I worked in hearing health care it was hard to even find good data on actual spl levels for gunshots. That was even from the guys writing the standards. You need specialized equipment to get any useful data. Luckily now you can buy meters designed for the task.

Howa

 

[mtnwrunner]

If you all recall.........I said it was a NON SCIENTIFIC CHEESY METHOD.
Bunch of redneck old farts sitting in an alfalfa field with a lull in the action.
So, yeah.....we ain't taking a cell phone app as gospel.
That being said, you can certainly hear what each suppressor sounds like and which one you prefer.

If your looking at the LPM look at the mach s not the anthem. Your already using a longer barrel with that 22". Id go with the OG to help cut down the length

I got to do a little testing of the OG over the weekend up on the canyon. Tikka 6CM 18" PVA .750 Taperless.

I did not get to shoot as many rounds as I had intended, but ended up about 20-30 rounds down the OG in various positions.

My initial thoughts are pretty positive. The balance is improved significantly for me compared to the Hydrogen K it was wearing previously. I'm not super picky when it comes to sound, but my buddy reported that it definitely had less "crack" to it than the OCL.

I have a potential issue with the threads inside the can I have reached out to Unknown on. I'll update when I hear back.

Shooting off the pack at 400.

This guy probably did not hear the OG. Unfortunately the Aoudad declined to participate in any testing.

 

[Bobrobheimer]

Am I right that there are no pre orders open yet for the OG L?

 

[Q_Sertorius]

I tried out the OG this morning. I didn't have anyone else around to compare volume or tones with, so I only have my own impressions.

I was not expecting otherwise, but it is not as quiet as the Scythe Ti. The first shot with my OG did make my ears ring slightly. It definitely was better than firing unsuppressed. I will almost certainly only use it on longer rifles in the future.

Edit - I was using it on my standard CZ 527 in 6.5mm Grendel with 18" barrel.

This is also probably user error, but the 1/2x28 adapter got stuck on the muzzle and came off the OG when I unscrewed the can. There was no easy way, that I could tell, to get it removed. I had to put the can back on and tighten it down, then unscrew it again. In a pinch, I could have used a pair of pliers, but I don't like that there is no flat surface for a wrench on the adapter (I recognize the design limitations).

If anyone has any suggestions for avoiding this in the future, that would be great.

What caliber and barrel length did you try it on ?

I don't see it as a problem unless you are switching between suppressors with different sized threads (or one has a 5/8 mount and one has a 1/2 mount). When I pick up my OG (today hopefully) I have adapters coming for two specific rifles, both have the smaller 1/2 threads. I already use an adapter on the one rifle. So I will be Rocksetting the adapters onto both rifles. I don't want the adapter coming off (but I ordered the tool just in case).

In my opinion, you need the tool to really put in the adapter. If you don't have the tool and it gets stuck in the suppressor, then I doubt you could get it out. If I was US/UM, I would not sell it without the tool.

What caliber and barrel length did you try it on ?

I edited the post to add this, but I was using it on my CZ 527 in 6.5mm Grendel with 18" barrel.
