i’m not one for vanity plates but apparently this one is available. the temptation is strong

Living over 50 miles from any NFA FFLs, Capitol Armory is a dream.

Good morning, folks! Four deliverables for you today. First, testing and analysis report of the T&K Vorix 30 Ti silencer on both .308 and 300 BLK. Also, a Hazard Map Brief for spatial looks at blast overpressure hazard reduction for both cases. Then, a podcast episode with the LayerX Strake 9 technical deep dive and the Vorix 30 Ti intro.

Lab Data Stuff

Report 6.232 - Today we examine the high fidelity test results for the T&K Vorix 30 Ti silencer in both the supersonic and subsonic ammunition combustion regimes with 7.62 NATO M80 and subsonic 190gr 300 BLK ammunition fired from 20-in and 8-in barrel bolt-action rifles, respectively.

Tools to help you in addition to the double-header report:

• Silencer Hazard Map Brief 8.1.29
• Updated Rankings (filter by .308 and/or 300 BLK)
• Podcast Episode (intro today and deep dive next episode, as is tradition)

Multiple combustion regimes? The humanity!

CliffsNotes

• A lot of folks are certainly making silencers. Here's a hunting gear company joining the mix. This is a purposely designed bolt gun silencer - light weight and somewhat compact.
• The Vorix 30 Ti is HUB compatible, 3D printed titanium, weighs a little over 10 ounces without a mount, and interestingly is a little less than 1.5 inch diameter.
• The PEW Science laboratory was asked to characterize this silencer in multiple combustion regimes, so that T&K Hunting could understand the range of personnel hazards, consistency, and performance, that their users may experience; and they wanted to understand the physics of their design and double-check their own testing. That is the reason for the two-test study today.
• We were very intrigued. One of the main reasons is that despite being 3D-printed, this silencer is not exotic inside. In fact, a strong argument could be made that this could be traditionally machined. However, what we have learned is that rapid prototyping and design optimization is a significant benefit of additive manufacturing. What you see with this Vorix report is an example of that. Very optimized traditional design.
• As described in detail in the report, they are essentially relying on highly optimized porting to relieve stagnation with the lower expansion volume without off-axis or annular re-routing. In plain English - they made the silencer smaller and still work well by designing it better through optimization. Again, more information in the report.
• Surprisingly high performance (to us, at least). And some of the physics were actually very interesting, including the almost rapid stabilization once things want to run away during initial high pressure jetting. For you silencer physics nerds out there, we have no doubt that this report is going to scratch your itch.
• We talk a lot about "silencer fingerprints" at PEW Science and being able to identify silencers by their signatures. An interesting tidbit about today's report is that the fingerprint of the Vorix 30 Ti has features that manifest across combustion regimes - in both .308 and 300 BLK. That is really neat.

Commentary:

It's not often that we find the testing and analysis of a conventional design exciting. However, studies of optimized conventional designs can prove very rewarding! For example - take a look at the Half Nelson from Q. Look at its subsonic 300 BLK performance. Then compare it to the Vorix 30 Ti. The report has a paragraph on this that you should read. Volume increases with the square of the diameter. And yet.... the Vorix wipes the floor with the Half Nelson in overall suppression and FRP control. How do you explain that? Design optimization. When designs get more advanced in pure technology or optimization, volume can be a poor predictor of performance. It is great to see yet another example of this known phenomenon.

Big thanks to T&K Hunting for trusting us to perform this 3rd party laboratory performance validation. They set out to make a hunting silencer and it looks like they did.

I hope you folks find the data and analysis useful!

1. Sound Signature Review 6.232 – T&K Vorix 30 Ti on .308 and 300 BLK bolt-action rifles. Multi-cartridge testing for this lightweight and compact bolt-action rifle silencer, to fully characterize its behavior. A little under 1.5-in diameter, and less than 8 inches long… yet bringing the performance? Pleasant surprises seem to becoming more commonplace in today’s silencer market, which is great! Let’s take a look at these interesting physics in this introduction to the report published today. (00:46:16)

As always, thank you so much for listening, and for your support!

Happy Wednesday!^{My dudes}

WAY better with NODs with that extended stock. So happy

But the question is how tight is too tight? Does it start at when its interfering with proper function? I know this definitely fits the bill as it's flat out touching the rail and I'll be getting a slightly shorther handguard to remedy that(10in on it now, going to 9.5).

Actual reason for the post is I finally finished can no 2 from my first approvals last week, ftn4.5 30cal can, absolutely goofily long on a 10.5 but it's stupid quiet from all the reports I've seen and vids I've watched so it'll be the can for when I want it to be as quiet as possible (already got another form 1 sent in to make a more practical sized can for it. Its mostly a fun range toy but since I reload and run powdercoat cast 230gr subs for it I decided it absolutely needed a can.

First pistol can, couldn't be happier with how this looks. Got a whole bunch of different subs to run through both of these tomorrow to see what runs the best. Already thinking about what can I want next lol.

Finally got my approval 5/16-7/20. Love this setup so far. Can’t wait to go shoot it!

Chopped down Ruger Mini-14 SBR from The Armory AZ with a raw Fireteam556 on a DD Zilch Mount.

Just picked up a threaded barrel for my G34 and tossed the Obsidian 9 on to see how it would look. Pretty hilarious if I don't say so myself.

Best PCC on the market imo

Recently got my two newest cans, the Griffin HRT-556 AM and HRT-5K AM out to the range together. Haven't seen a ton of info out there on these, so I figured I'd share. TL/DR is I really like both of them.

I got the 5K to primarily live on my 14.5" M4A1 RIS II, and the full size for my 11.5". Decided to try out Dual-Lok for both of these. I'm using the included EZ Brake with the full-size, and picked up one of their Bayonet Brakes for the 5K, which reflexes back behind the shoulder of the barrel threads by about 3/4". Perfect for the M4A1, and it ends up adding a hair under 4" total to the bare muzzle length.

This was an indoor range day for me, which makes it more difficult to pick out the nuanced differences in sound between various cans, but I was really happy with the sound performance from both. On the 11.5", the full size is predictably quieter than the K, but the difference is not massive. The K was a little bit louder on the 14.5" than it was on the 11.5", probably because that muzzle device sits a significantly further into the blast chamber. Would not shoot it indoors without ears, but still impressive performance for only adding 4" to the end of the gun.

Both are very low back pressure. No noticeable increase in gas to the face, and no noticeable increase in how hard/fast the rifles were cycling. The cooling fins/vents on the full size do seem to seem to make it a bit slower to heat soak and faster to cool off than the K.

Overall really happy with both of them.

I have a friend who has a P320 X5 that he wants to suppress and has narrowed it down in between the Deadair Mojave 9 and the Rugged Obsidian 9. He has done some research, and has seen some videos that say that say the Rugged will require some tuning for the 320 but can’t find any videos about the Deadair and the 320. He doesn’t have Reddit and asked me to reach out to y’all to try to determine which of those two suppressors will require the least amount of tuning of his P320 in y’all’s experience. And yes he is dead set on using a P320.

My first ever time using national gun trust and I paid for their instant fingerprint card to eft file. I got the email with the link and used that to access the card now on day 2 of trying to make it work and I’ve reached out to them but every time I get to the generate page it says no valid purchase found. I had an easier time getting my finger prints to work on a silencer shop kiosk.

I’ve got a bunch of live dealer sample RPG-7’s and finally got some new furniture for them.

It’s the lil’ things in life
