Integrally Suppressed Ruger Precision Rifle Video

[Lowlight]

Thursday RayDog from ThunderBeast Arms was kind enough to come out to Fort Morgan with Myself, Alan from Machine Gun Tours and Witt Machine (Ken, Jessie, Alex) to sound test their suppressed Rugers.

We tested the following

308 RPR - Supersonic and Subsonic
6.5CM - SuperSonic
6CM - Super Sonic
556 RPR - Supersonic and Subsonic

We used two meters, the TBAC B&K Meter, and the Larson LxT, both placed at MilSpec Distances for testing.

Quick Teaser video before the official numbers are compiled into a spreadsheet.

More to come by way of a complete article, but first some shots at 800 yards with the 556 Ruger and Prime Factory Ammo

 

[Ayoung1]

I'm interested in the results. Currently I have no interest in the RPR but this could possibly sway me.

 

[Frankr]

How long is the OAL of the barrel/suppressor in 556.

Personally a 555 integral with an OAL of 16" would interest me as a truck gun and short range coyote rig.

Probably would have a 11-12" barrel

 

[Lowlight]

I spoke to them about building truck guns ...

There is a gem of a detail that will let them get really creative here and I think you'll see it happen

 

[djarecke]

Very cool. The TBAC guys have definitely hit a niche here.

 

[Lowlight]

This is a Witt Machine Suppressor working with Machine Gun Tours,

TBAC just helped us with the sound testing, super awesome for them to come down and assist

 

[D̷e̷v̷i̷l̷D̷o̷c̷A̷Z̷]

That thing has a lot of cool factor going for it. I just can't justify the wait on a suppressor if I can only use it on one platform. Maybe that's just me or my place in life right now. Perhaps when I have more discretionary funds it would make more sense.

That being long said I like that more people are offering support for the platform.

 

[Ledzep]

Ought to do a ported counterbore to keep barrel length in the 16-18" range. Especially with something like .300 blackout you could counterbore 8" and have a wicked quiet, short setup.

 

[Lowlight]

Ported versions were tried and were not as good as what we see here.

They can easily adjust the barrel length here. They can do a 12" barrel if you want, because it is part of the suppressor it is just one stamp.

They originally wanted to maintain the barrel length for velocity, but with so many people talking about shorter versions, it is easily achieved

 

[Lowlight]

 

[Frankr]

Good info.

How long is the baffle stack?

Does the space behind the baffle stack act as a expansion chamber?

very excited about this.

How does this this compare to other suppressorsv

 

[Greg Langelius *]

Some of us may have kicked the idea around in the abstract, but TBAC has made it work. I think it's a concrete contribution to our sport, and to those who need this product for more serious purposes.

Bravo, TBAC.

Way to go WITT MACHINE SUPPRESSORS and MACHINE GUN TOURS!!!

Thanks to TBAC for bringing their equipment down and helping out. It's great to see industry competitors help each other out for the betterment of the sport!!

Looking forward to this product!

 

[Greg Langelius *]

I stand corrected, thank you for the heads up.

We couldn't have done the Milspec test without RayDog's experience from TBAC. Our industry is so small it and it is great to work with the people in the industry who have the knowledge. I enjoyed learning a thing two.

 

[atomic41]

What is pricing and availability on these? I was planning to buy a new rifle soon, this has the potential to derail my plan.

 

[Lowlight]

Complete Rifle: $2899

Upgrade Kit: $1699 (Proof Research SS Barrel, Suppressor, Handguard)

Both In stock at Machine Gun Tours, call Alan he has them.

 

[Steel head]

Cool that Witt machine is doing those.

Sound Meter Testing
Meter Testing, the Witt Machine, Integrally Suppressed Ruger Precision Rifle

Before I get started, I want to thank RayDog from ThunderBeast Arms for coming out to the range with their B&K2209 Sound Meter. Ray and TBAC were gracious enough to support this project, their expertise in this area was an important component.

If you have not already checked out video stop by here. [IMG2=JSON]{"data-align":"none","data-size":"full","src":"https:\/\/www.snipershide.com\/wp-content\/uploads\/2017\/08\/SH_HD_substestinglxt-1-2-1348x900.jpg"}[/IMG2]

Larson Davis LxT
This project would not be complete with out sound meter testing. When I spoke to Alan from Machine Gun Tours about it, I wanted to bring in some one with a real sound meter. I know Alan just got back from the Competition Dynamics, Magpul Governors Match in WY. So a quick call to ThunderBeast Arms and Ray agreed to lend us a hand.

I initially contacted Larson Davis to purchase a LxT sound meter from them. Larson Davis was easily two weeks out, so I figured we would just use the TBAC B&K2209. Little did I know Ken from Witt Machine had a Larson Davis LXT. Hearing this was great news; we’d have two meters for comparison.

Ray monitoring the activity
Ray being a pro in this field schooled everyone on MilSpec testing, and the plan was to shoot both supersonic and subsonic ammo through each Ruger Precision Rifle.

On hand we the 308, 6.5CM, 6CM, and the 556 all ready to test. We only had Atomic Ammo Subsoncs for the 308, 556; everything else would be shot with full power loads.

I won’t drone on about the results, so here is everything we did with the Ruger Precision Rifles. 556 RPR

This video is a behind the scenes look featuring Ken of Witt Machine and Alan of Machine Gun Tours.

The next video will demonstrate how you can upgrade an existing Ruger Precision with a Witt Machine Integrally Suppressed Kit.

The Kit contains a Proof Research Steel Barrel, a Witt Machine Suppressor, and the handguard. Installation is very much the same as changing the barrel. It requires about an hour worth of work and some AR 15 tools. It’s a super simple process.

Machine Gun Tours currently has these in stock. Both the complete rifles and the upgrade kit. The complete rifle sells for $2899, and the upgrade kit is $1699. Atomic Ammo Subsonic

What kind of MV did you see? Or did you not measure that?

 

[Lowlight]

we measured the first time out, and I did shoot to distance with them, but honestly I did not record the numbers.

They have full barrels underneath so the numbers are super close to normal rifles...

The 6.5CM is a 24" barrel underneath the 308 a 20" so you get very normal numbers

Since my Labradar is broke, I didn't do this time, it actually broke the last time I shot these.

If you look at the parts of the video with me and Alan on the range you can see the wind flags straight out and the labradar in the picture, that day it blew over

so last question, cant remember if you addressed in the video. When the barrel is shot out, can you replace just the barrel or do you have to replace the whole thing?

 

[Lowlight]

You can send it in, they will remove the monocore from the old barrel, and replace it on the new barrel. I think they are gonna charge $100 to swap it out for you.

They are attached so you don't need two stamps when they decide to do shorter barrels, but they can be replaced and swapped out by Witt Machine

 

[JFettig]

You should probably figure out how to use that meter. The striker alone will meter higher than your imaginary numbers.

 

[spife7980]

Cant wait to see how this is gonna play out.

 

[JFettig]

Well if it helps, here is a Rem700 dry fired

popcorn ready.

 

[djarecke]

Great 2nd post, JFettig. This must be a Hide record to achieve the rank of Uniformed Shitbird in 2 posts. How high did your Airsoft striker meter?

 

[Lowlight]

Did you test the striker on that rifle from the front ...

So you are saying TBAC has not idea how to use the meter ...

There is a difference between metering the front and sticking the meter at the receiver

 

[Lowlight]

The funny part is the entire thing was shot on video, I have hours of footage, I will string it together to "prove" how this was done and the numbers as recited in real time ..

Argue that with the resident geniuses, it's unmistakable

 

[_Windrider_]

Im thinking someone doesn't know you were using DOD testing protocol as well which is very specific as to where the meters are to be while testing.

 

[Lowlight]

There is a competitor to Witt and Machine Gun Tours which claim to be the quietest and most accurate Integral Suppressed System, and they are doing hit jobs ... their owners came on FB arguing everything, and I am sure they are sending out their minions now. Take it with a grain of salt.

I am trying to scour the footage to find a dry fire, I know Alex pressed the trigger at least once with no round in, the problem is finding one or two shots across 2+ hours of footage.

Funny thing the Larson was very different from the B&K 2209 at times, not always, but at times. In every case the Larson was actually registering less than the B&K Meter.

I have the footage, I am not worried about it...

Talk about a clue. It's called volume, the Witt Suppressor is 28" long... so D'uh, it's gonna be quieter than what you are used to seeing with a 7" or 8" suppressor.

The video doesn't lie and I highly doubt Ray would allow his picture to be involved if this was all bullshit

 

[Lowlight]

I asked Alan to ask Ken (who has a Larson Davis LxT) to check the 556 RPR when dry firing

But with my cheesy Amazon meter, it reads right around 60db, the loudest I got with the meter right next to the receiver was 63db most cases it was around 58 db


I know it is a shit meter, but it just reading the click of the dry fire... firing pin fall, so it's not a gunshot.

I know Alan is at some Machine Gun shoot, so he will have to contact Ken, etc, I don't have the Witt contact details to call them.

 

[ChadL]

$2899 for a complete rifle or $1699 for an upgrade seems pretty darn reasonable to me.

it is a pulse measurement which is a loud sound for fractions of a second. To accurately measure you need a mic with a 20µs rise and a sample rate of at least 102.4khz. With a slower sampling mic you don't actually catch the peak sound waves you catch the backside of the slope so its an artificially low number. FWIW there aren't any hand held mics that I am aware of that hit the current milspec (MIL-STD-1474E) for silencer (impulsive noise) testing. Not trying to shitpost just talking fact.

4.7.5.2 Recording equipment for impulsive noise. Equipment for capturing and storing impulsive noise shall have a minimum of 16-bit resolution, with 24-bit resolution preferred, and a sampling rate of a minimum of 192,000 samples per second. The analog signal shall be filtered, using a Bessel type with a 40-kHz cutoff frequency. The roll-off rate shall be not less than 36 dB/octave.

 

[Lowlight]

Well aware of that, but clearly there is a difference in dry fire, firing pin sounds...

Look at the meters we used, both are calibrated, one digital and one analog that is MilSpec

The guys arguing the numbers are saying two things,

1. The Larson Davis was not read correctly, the wrong number was taken, not the peak but the max
2. Ray from TBAC did not set up the B&K 2209 correctly,

So, while the test was conducted with a 3rd party (Ray from TBAC) and we used two completely different meters for comparison, this was a bad test.

even the guys arguing the numbers as false, (Who are direct competitors by the way) they had a video were the firing pin was 116db and their first shot metered at 115db

[djarecke]

This post is extremely irritating.

I have no vested interest in this, but JFettig obviously opened an account to question TBAC's integrity.

So how about it, JFettig? Let's see your meter numbers from a dry fire, you shit bird.

Or better yet, tell me what company you're affiliated with so I can spend money somewhere else.

 

[Lowlight]

The company is SWS (Suppressed Weapons System)

They are in full hit job mode on FB over this and saying Witt Machine are defying physics with this can, and the numbers posted. (If you look you can clearly see the Witt is a bigger can)

They agreed the Larson was "probably" set up right but that Ken used the wrong numbers, and constantly ignore the B&K numbers until pressed. At which point they argue that TBAC / Ray set the Meter up wrong and that Ray did not know how to use it correctly. They said this is more involved than just reading about the meter on the internet. That is a bit of a insult against a company. that would mean everything TBAC is wrong.

But SWS claims to have the quietest and most accurate Integral Suppressor on teh market, this directly competes with them, and exceeds their results.

I would like Ken to set up the 556 RPR and from the same position at the muzzle like we tested, demonstrate the dry fire click as being that far away it has to be low. With a 28" long suppressor and the meter forward and to the side, it will clearly be less than 109db ... interesting the image posted is the same meter as the SWS guys are using.

They told me today, posting these numbers on my site will put egg on my face.

 

[POI_Shift]

Im thinking someone doesn't know you were using DOD testing protocol as well which is very specific as to where the meters are to be while testing.

Positions yes, equipment no.

 

[Lowlight]

I believe the B&K 2209 is...

I think it is covered under MIL-STD-1474C.

 

[POI_Shift]

I believe the B&K 2209 is...

we are at 1474 e as of 2015. 1474c was the 1991 standard.


https://www.arl.army.mil/www/pages/343/MIL-STD-1474E-Final-15Apr2015.pdf

 

[Lowlight]

I believe it still meets the standard, it is being used ...

That was the only reference I could find with a quick look

 

[Frankr]

Holy Hell. Talk about purse swinging.

I understand that besides the raw numbers the tone of the suppression makes a difference also. Instead of crapping on innovation people should be excited about the prospect of seeing new products for a great product.

Lowlight - Thanks for posting this! This is by far one of the coolest things (probably the coolest) I have seen for the RPR. Were you guys able to compare the suppression and tone against any known suppressors (i.e. TBAC Ultra 7, SiCo Omega, etc..)?

How did the handling feel with a 28" OAL barrel length?

I was all set to start gathering up parts to build a .223 Tikka T3 or Howa in a chassis, SBR it to 10-12" and put a good but fairly short suppressor under the handguard.

The fact that the Ruger comes in 1:8, basically is in a chassis and can get it with 1 stamp would be sweet!

 

[Lowlight]

comparison

 

[JaneDoe]

Great to see this. Reminds me of the Accuracy International Covert but haven't seen any talk of those in a long while.

 

[anon]

Both sets of guns, meters, and people on the same range in a spirit of cooperation could establish a baseline.

 

[POI_Shift]

I believe it still meets the standard, it is being used ...

That was the only reference I could find with a quick look

Its good for positioning mic's and standardizing that but I'm pretty sure only a few out there hit the actual mil spec. Thats why these mic's are like $5-6k and the B&K system I run is over $40k
