Unknown suppressors OG testing

[Kaleb]

I ordered the tool and the adapter. After I try it on a few different rifles it will stay on a 6creed threaded 5/8. Like most are saying id glue the adapter on the rifle and never look back. If for some reason I needed to remove it and couldn’t easily enough I’d quit trying and order another adapter.

I had a geisselle super duty upper come in with a hux brake on it. I don’t have a hux suppressor so wanted it off. It was on there! I called the manufacturer to see what they used to secure it. The assured me it was red lock tite. A suppressor was not going to unscrew that. I had to use heat and a pretty good whack.

I know that cell phone microphones don’t really do anything for most people, but here is a video of the first shot.

Cellphone recordings are not ideal, but not totally worthless either.

The manufacturer of your cellphone should have selected a mic with frequency response that matches the human ear. In other words, when you speak into your phone, it would be best for the device to capture your voice in the way that people actually hear.

Likewise, manufacturers of the phones that the rest of us are using to watch your videos should have selected a speaker that produces those sounds correctly.

Of course either phone, the one recording or the one for playback, might manipulate the sound. Maybe even YouTube.

I still see value in those clips. Both cans sound fine.

The Scythe Ti did seem quieter to my ears, on my phone. It also seemed flatter, if that makes sense.

If squeezing a wet paper towel on your muzzle device takes care of roksett, how the hell does it stand up to hunting or shooting in the rain/snow?

And water vapor comes from a wet paper towel and a blow dryer but not rain/snow and a warm/hot barrel?

That is a good question. Maybe @Formidilosus has some experience or insight.

My understanding is there's still some force required to break the bond. Imagine the "forced" introduction of water vapor with that paper towel method is more effective than just water being around the connection and having a hot barrel.

That was just one method I've seen that makes sense and seems well thought out. Never removed a Rocksetted muzzle device, just looked into methods for removal before using it.

Phones also employ AGC -- with unknown time constants.

Now add sophisticated DSP (especially echo canceling) enabled by default.

I suspect additional proprietary euphonic tweaks are in there someplace, at least for more expensive phones.

AB makes an adapter that fits as well, with wrench flats. They're hard to find in stock though. Mine is rocksett onto the barrel and I've had no problems with a raptor or the OG (only had it a week)

Wrench flats don't do much good if it's stuck in the suppressor after lots of shooting and carbon fouling. I like the UM tool because of that. IMO the adapter stays permanently on the barrel unless you're trying to go cheap and save $25 and reuse the same adapter for another rifle. I've removed Rocksett muzzle devices before and it's not that difficult and didn't need moisture just a little muscle.

Rockset and 5 gal bucket of water. Let it soak while you eat lunch. Then they pop off easy. Set the can in front of a fan and it dries in 10 minutes

That's good to keep in mind if cellphone recordings are used.

I'm scheduled to visit a dedicated lab with anechoic chamber and analyzers, just for consumer products like phones. Should be interesting but it's hard to keep track of the extent that sound is manipulated by each phone processor.

On a side note, NIOSH developed their Sound Level Meter app for iOS because it's a known quantity with only one manufacturer, and Apple allowed some access to the mic system. Android has too many variants.

I will record some OG shots once I get a bit of time with it.

B&K 4133s at 192 kHz should allow me to generate TEF waterfall plots, which I suspect will prove informative.

That'll be a huge contribution to this thread! Should help educate with the frequency content.

Will you do bare muzzle compared to OG?

Bare muzzle might exceed max amplitude and distortion limits of the 4133 though, but you could work around it with setup or a different mic. You probably already know that, but thought I'd mention it just in case.

Update on my thread issue:

While swapping out my Hydrogen for the OG, I noticed a very gritty feeling when threading it on. I backed the can off and attempted to clean the threads with my shirt and some paper towels. I went about a half turn into the grit again and the can locked up tight, but did not feel like it was against the shoulder.

At this point the OG was completely stuck in either direction. I left it on for the rest of the weekend and when I got home I soaked the threads in kroil overnight. After some kung fu grip and repeated applications of kroil I was finally able to get it loose.

The threads felt very gritty on the OG despite being cleaned multiple times and working fine with the Hydrogen and another can. Finally, I was able to get the threads to where the can would actually tighten against the shoulder by hitting the inside and barrel threads with a nylon brush and oil. The lettering on the can now lines up about a 1/4 turn from where it was stuck.

The only cause I can come up with is that the OG had some of that powder from the printing on the threads that caused it to bind up until it was thoroughly cleaned off. Despite hitting it with an air compressor when I got it, there was definitely some sparks during the first 10 or so rounds of shooting.

Just a heads up for anyone that might run into the same issue. I shot the can again today and it was great. For sure a deeper tone than the OCL and the length and improvement in balance are the real perks for me. I can't wait to get some more hunts in with it.

Not sure if it's in any way related, but awhile back I recall Proof Research having to tell people not to put a Warcomp on Proof barrels because they get stuck...this is wayback memory so it may not be accurate at all, but IIRC, it's a machinist-level bit of knowledge about thread style. Not thread pitch, but the actual cut. Apparently there are 3 styles of cut for any pitch, and if the two are too close between how the muzzle device and the barrel are threaded, they'll seize up after you get them on. Apparently it's not the same as galling, either. Any machinists or gunsmiths out there who know anything about this?

 

[nm.otter]

Bare muzzle might exceed max amplitude and distortion limits of the 4133

The 4133 pretty much hits the wall at 160 dB (as a low distortion precision transducer). I'll certainly test bare muzzle at shooter's ear, but not likely much closer.

I don’t think I’ve seen this discussed yet, so it’s probably worth asking:

Has anyone tested to see if debris or ice buildup between the suppressor recess and the barrel causes a POI shift or other issues?

Interesting thought.

I Imagine such a thing would be very situation specific. I.E. a 16" 0.750 contour barrel and some pine needles might not have a hiccup but a 22" kimber'ish light profile stuffed with wet sand is probably going to have a POI shift.

If it worries you, I guess you could put some tape on it.

I'd like to hear your thoughts on the difference between the OG and the Harvester Evo (once you get away from the block retaining wall) since that's what I'm currently running and debating an "upgrade"?

Here is my honest not an expert on sound or suppressors opinion. I also have tinnitus in my left ear and it is fairly sensitive to gunshots.

To my ears the OG is louder than the evo from behind the gun. Not a lot but definitely noticeable. Again not an expert I don't know if it's DB level, frequency, or both.

Next we were shooting 581 yds in an open field with woods down both sides. About 500 yds down there is a ditch. We took turns getting in the ditch about 75 yds west of the firing line. The shooter picked which order to shoot the rifle. After both were fired I blindly picked the OG as quieter and he said he couldnt tell the difference.The video link below shows the test. I would be interested to hear other peoples opinion on the video. In real life you could barely hear it leave the rifle then it cracks the sound barrier as it goes by then the sound of it hitting the plate.

My thoughts-

I bought this suppressor to shorten the length of my rifle, move some of the suppressor weight rearward, and decrease overall weight. The OG accomplishes all three. If I was expecting it to be significantly quieter I would be disappointed but that was not my priority. I paid $350 for my evo when they were being discontinued so if money was an issue the evo would be the better buy IMO. The OG appears to have less chance of failure and my son's evo did blow in half in the first two weeks he owned it. Silencerco promptly fixed and returned it but if that happened in the backcountry it could be a problem. For my goals on this particular rifle I am happy with my purchase.

Thank you. I paid full price for my evos and feel they’re a bargain. The fact they came with the 1/2x28 hub was a bonus too since I have several 1/2 threaded barrels. I bought two evos first then a nomad ti. I didn’t find the nomad ti to be any better to my ears so bought two more evos. I’m the curious type and wanted to try the OG based on this forum and all the discussion about tone and all that. I’m happy with all my suppressors so if it’s fairly close to as quiet as evo nomad scythe polonium cat Noah I’ll be happy. Especially with the length the OG is. Will see as soon as it gets turned loose.

 

[Styer22]

Well my OG got delivered to my dealer yesterday. I was gonna go get the paperwork started but on the way a dump truck spilled some gravel peppering and destroying the front bumper hood and windshield of my 10 week old truck . Needless to say I didn’t make it to the dealer and now have to wait till they reopen Monday. Plus the fun of dealing with a brand new truck that’s now damaged.

Yeah I'm not really hearing the tone thing that was discussed especially down range. I have some other things to experiment with next week to try to understand. Although as I said before it may be because of my bad ear.
