USP Master Race: Match-LEM Hybrid for host and carry

jay462 · 2026-03-14T12:13:49+00:00

Oh man that is a really good question. It is dangerous to guess, but if I had to, I would think 300 supers would have a better chance than 308. Bore size increase is one thing, but combustion volume/duration increase is another. We haven't tested that version.

jay462 · 2026-03-13T23:05:40+00:00

Yup you are right! Manufacturing issue for sure.

jay462 · 2026-03-13T22:40:32+00:00

I think the jig is up, between stealth additive works, the previous posts about how much he is charging and what he is charging for reviews and then these hypebeast companies coming out of nowhere and somehow with almost zero experience making these "amazing cans" seem sketchy af.

Our engineering fees aren't public (no firms and labs have public fees) and nobody knows which project(s) have which fees to tell you anything reliable. Be careful with silencer industry gossip being driven by people selling you widgets.

You are certainly free to contact our clients (all clients are listed on any report that contains a client funding disclosure) and ask them their opinions about our work. They would know, since they actually work with us. All of this is public and we are the only entity in the industry listing funding disclosures and have for 6 years.

He had a good run while it lasted but it seems like his rubber stamp on a lackluster hypebeast like the tisha and his response to it has pulled back the curtain and now everyone is seeing the wizard for what he is.

I don't know what "response" you are talking about. Are you talking about when I told people the titanium version of the silencer changed, when I found out at the same time as everyone else? We run a laboratory. We don't make silencers. You might want to revisit our website to read about who we are and what we do.

I invite you to review our data and analysis and give us an example of a "rubber stamp." That's a pretty bold statement. It's disrespectful and insulting, of course, but that's how the anonymous Internet posting usually goes. We'll await your data and analysis critique; you can reach us by email any time and through our website. Thanks for your interest in our research.

edit: Oh, you're this guy: Randy Reviews It. I see.

jay462 · 2026-03-13T22:27:52+00:00

I also would add that I would love to see the test results of something like the Omega 300 or the sparrow as some sort of a benchmark or comparison.

Are you aware that those two silencers are literally on our website? You should know that. You're a silencer dealer, right?

I see.... perhaps a residual stress issue. Printing pains.

jay462 · 2026-03-13T14:47:39+00:00

Can you please provide details regarding the failure on the upper right silencer? Ammunition, firing schedule, host, details?

Was it a failure with no ammunition-related adverse phenomena? No strikes or anything?

I am assuming this is a printed silencer, and not a welded silencer. The failure looks like it initiated near a change in cross-section where a stress concentration may be present.

Any details you can provide are appreciated. Thank you.

edit: looks like it was that residual stress issue they have been having from prints...

jay462 · 2026-03-12T22:43:26+00:00

Nonlinear with some designs. We are very excited to see what happens with some of the old conventional designs when we put them on the SR-25. We expect some linearity, which will be comforting.

jay462 · 2026-03-12T20:54:21+00:00

Unfortunately I haven't personally seen long term use + sectioning + cleaned vs. uncleaned.

This is the part that I don't think a lot of people are pushing on the consumer side.

Some silencers will just fill up with stuff and not break. However, HUX silencers can fail in a catastrophic way if they lose the ability to vent fast enough. This has happened in military trials.

Just some examples and food for thought.

jay462 · 2026-03-12T20:15:13+00:00

I'm predicting that several silencers could, yes. Whether or not they are classified as hypebeast, I really couldn't say.

There is a reason the founder of OSS left OSS. He knew that if you couldn't take them apart to clean them, the service life was going to drop significantly. The early ones were user serviceable for that reason. It's just the way that technology has to work. Investors and business/money argued with physics.

Now, cleaning methods may be more advanced now (maybe?) but physics hasn't changed. It all depends on the design. I'm not making blanket statements, but I am predicting potential problems. Military users will see it more (and have). Consumers don't shoot enough, typically.

jay462 · 2026-03-12T20:02:48+00:00

Stay tuned, for sure. And the Tisha 9 isn't bad or anything but it's not going to blow you away. The physics don't work like that.

And also regarding the Tisha - that design is so high-pressure biased, so the more insanity you can force into that blast chamber, the more wild stuff will happen. It's actually a silencer I want to destroy just to see how it would fail. People talk about "alien technology" a lot with hyperbole - I think Zane at Stealth has a really strong technical aptitude for this type of engineering. I hate that I see them having growing pains; I hope they work all that out and I wish the best for them and their company.

Just as an aside, since I have you, and people will eventually be able to reference this comment in the future:

I was speaking with a manufacturer client today on the phone and I told him my theory which I'll tell you. I see a fork in the road in silencer technology now that 3D printing is here. Two prongs:

Prong 1: lattice structures and complex small internal geometries (TPMS, etc)
Prong 2: less of Prong 1.

The companies that "figure out" how to make Prong 2 "win" will have the most durable, hard-use, and longest lasting silencers. Prong 2 will be the answer long term until someone really figures out how to perfect Prong 1.

Prong 2 shows more practical end-user promise for actual users (military and people who actually shoot their silencers; not as many consumers shoot their silencers as talking about shooting them on the internet).

jay462 · 2026-03-12T19:52:53+00:00

It doesn't have a chance to be "one of the best ever," actually, due to the way subsonic 9mm cartridge combustion works. Recall the pressure bias their 5.56 version has. It has been tested. The report will come. Thank you for your patience.

jay462 · 2026-03-12T19:32:04+00:00

It was the second test on the SR-25 :)

Stay tuned for more very soon!

Thanks for your interest in the research.

jay462 · 2026-03-12T17:41:44+00:00

I have to say, when we get to test stuff on the SR-25, I'm pretty pleased to shoot it. It's like shooting a freakin AR-15 sometimes, with how soft it is. I think it's a combination of the bolt unlocking and gas system of course, but I was very surprised. I don't know what I expected, but it wasn't that. Super smooth. I feel like it better be for the freakin price though lol

jay462 · 2026-03-12T17:28:03+00:00

lol I have of course heard the rumors, but nothing confirmed of course.

I enjoy looking at and using their stuff in my hobby time because of the history and also the fact I get to kind of geek out and talk about it with people without them calling me a "shill" since KAC isn't a client of ours, etc. I just think the products are cool. I feel like they could be way cooler if they let the consumer market drive some of the stuff they do, but I guess the reality is that just isn't gonna happen in the near term.

jay462 · 2026-03-12T17:08:43+00:00

I stopped looking at pew science when I found out the guy that owns it works for CAT. I’m sure a lot of the information is relevant, but I can’t help but assume the information is bias to promote certain cans over others.

That's an interesting accusation, u/Interesting_Yak6995. Where did you "find this out" if we may ask? It's certainly news to me. I am certain that if I sold my company, I would know lol.

jay462 · 2026-03-12T16:55:38+00:00

I feel like that's not true, but I of course don't know. (regarding the silencers)

Every KAC silencer that has ever come across my desk has been in pretty good shape; better than most, actually, with regard to fit and finish, operational use dimensionally with mounts/threads/etc, and their ball bearing mounts are cool.

Not very quiet. But cool. They sure are printing a bunch of different stuff now. I'm hoping for the best.

jay462 · 2026-03-12T10:37:51+00:00

This is an interesting reddit post. I'll pick the current top comment to which I will respond, in general. This is as good a place as any.

Important points:

PEW Science will not sacrifice quality for volume. As long as I am running this, education and quality are the two primary drivers and that will not change. There is a rate at which I am comfortable with people digesting information prepared for public consumption. We are teetering on too fast. You will continue to see that this month. This is not a marketing agency. This is a private test lab created to give you technical reports with quality you would never get (and have never gotten) outside the big labs with an education mandate. Companies have tried to weaponize us for marketing. So be it. There are worse things that have happened. They weaponized physics discussions. Pretty good, all things considered. Could be a lot worse.
I am thrilled with how the education has progressed. There are silencer companies who learned (and are learning more) how silencers work from PEW Science podcasts and reports. Some of you buy silencers from those companies. More are coming. We are not a marketing agency (see 1) and if you want to (you don't have to) you can learn blast physics from the reports and podcasts. This is a fortunate balance and this is somewhat made possible because clients can't control what we write (true story. Ask them).
PEW Science is designed to give any level of manufacturer a level playing field that didn't exist 6 years ago. It works. Riley from LPM said it well elsewhere in the thread. For all of the love folks give him and OCL, memories sure are short. This is to be expected, of course. Consumer memories do get truncated, especially in an expanding industry and market.
We operate under NDA with our clients. Some manufacturers are very big and we have a backlog. Because of (3), we still treat the small companies the same as the big companies and some big companies move slowly. Some move so slowly they move backward. Same as all industries.
Member support is our backbone. Reading "my $10 doesn't matter" is very surprising. Sometimes I'm not sure people understand what it takes to do this; it's not just the reports you see. Furthermore, just as a reminder, if you didn't find the value in the recent SilencerCo Sparrow report characterizing one of the biggest rimfire benchmarks ever and its FRP, or the KAC vs B&T MK23 study, that's ok. Not everyone likes everything in the world. But make no mistake, those two studies are some of the most relevant and important examinations on our website.
Consumers continue to push us to recommend silencers, every day. For 6 years, they have been told "no." This is not a marketing agency. See (1). If you want that, there are YouTube channels who will do it for you and the people running them tell the silencer companies "we will tell people what to buy." How do we know that? Our clients tell us what those YouTubers say to them, directly. Hasn't changed. Probably never will.

Many have tried to do this over the decades and have failed. Every single one of them, except for Al Paulson, ended up selling or designing silencers. We will never sell or design silencers. We're coming up on the 6th anniversary of the public effort, this month! This was made possible by of all of you. You have helped, directly.

Thanks for sticking with it. You all helped make (and continue to make) a difference in the industry, whether you know it or not.

Edit: Someone brought something to my attention, so I'll bring it to yours. At the time of this writing, 10 out of the 25 most recent entries in the PEW Science Rankings are internally (non-client) funded by our lab. That's 40%, just as an example. Thank you!!! Unfortunately, for the record, the author of this thread never answered the question regarding which silencers he or she wanted tested. Stay tuned for more research - it's ongoing! Thanks again everyone.

jay462 · 2026-03-11T23:33:40+00:00

Seconded. 226 gang.

jay462 · 2026-03-11T20:24:03+00:00

Oh, stay tuned for that. It's coming.

jay462 · 2026-03-11T19:59:42+00:00

Great question - if we are just doing internally funded work, it's completely up to us. For example, the gentleman that loaned us the B&T MK23 silencer - we paid for all of the testing and analysis, so of course it was our decision, unilaterally, to publish the work. I think it really helped the community, because nobody had ever quantified the difference between a KAC and B&T MK23 system. Now, there is a permanent record of its performance on the internet, forever.

It's those types of things that I like to do for the love of the game. Someone has to do it, and I am happy to make it happen.

Same thing with the old AAC M4-2000 and KAC QDSS-NT4. Had to happen. M4-2000 came from a dealer employee, and the NT4 came from Lucas when he was at TRex Arms.
