1st Suppressor / 1st Day Out (HUXWRX FLOW Range 36 Ti)

[GS455]

I once shot a half dozen rounds from a buddy’s bolt gun with a popular can from 10 years ago. I think it was a Gen1 RPR. I was blown away with the amount of suppression and have been pining for one ever since. Beyond that I have zero experience firing suppressed. A few months ago, I put out an inquiry for suggestions, and thank you for the responses :

I went with the new HUXWRX 36ti in the hopes of getting it my on M76 and M49, optimistic that the newer flow-through design would behave well on them as well as other semi milsurps. This was an interesting experience. I had three hosts to revolve through today. I shot five round groups before and after and observed peculiar (to me), inconsistent results between rifles:


RPR in .308

• This is a sub MOA gun when I do my part with the ammo it likes (168gr FGM)
• When suppressed it’s PoI shifted 3.5” down x 1.5” left
• Report was a fairly sharp, loud snap but does not ring the ears

RAR in 7.62x39

• This is a 1.25” gun with best performing ammo, so far being Rommy surplus :-/
• PoI shift was 2.5” straight up with no drift in windage
• Report was a pleasant sharp snap

LAR8 Elite Operator (basically Rock River’s AR10 pattern from 10 years ago)

• I fired a string with it’s Vortex flash hider and got about 2+” group using XM80 Lake City, 150gr “ball”
• I then fired a string, bare-muzzle (w/o the Smith Ent, “Vortex”) and got abou 1.5” group (THAT was a surprise)
• Next, I fired five rounds with the 36ti and got the same 1.5” group with literally NO PoI shift (huh?)
• Report was quite a loud crack+POW that would almost ring my ear.
• Perhaps not hearing damaging loud BUT not nearly the amount of suppression as the .308 bolt gun. Is this to be expected?

All in all, I was pleased with the performance on the two bolt guns. From what I’ve read I believe a traditional baffled can would be even quieter on bolt guns. Yes?


Takeaway/questions:

• Is it typical for such a PoI shift with vs. w/o the can.
  • Strange that the .308 RPR would shift down and to the left whereas the x39 RAR would shift straight up.
• While I need to do further testing it’s also interesting/revealing that after all these years the Vortex flash hider unbeknownst to me, may have been hindering accuracy on the LAR8
  • Why no PoI shift on the AR10 ?
• AND why I this semi-auto vs. the bolt guns so much louder. Typical? Moving parts and places for gasses/sound to escape?

Thank you for taking to time to review this and offer any contributive insights.

Alright, I’ll try to address your points. First, your can is overbored for .30, being a .36 bore. So you can expect it to be louder than an identical can in .30. Being a flow-through can, yes it is louder on a bolt gun than a traditional suppressor. Second, POI shift is going to depend on barrel harmonics, and as long as it’s repeatable, it doesn’t really matter all that much. Finally, a semi will always be louder than a bolt gun, yes due to both moving parts and gas “popping” out the ejection port. The flow can does diminish that port pop, though. As for overall noise, consider that with supersonic ammo, all rounds will not be technically hearing safe due to the supersonic crack. For the quietest experience, try loading some subsonic rounds in your RAR and you’ll have a blast—figuratively, not literally. All in all, nothing you mentioned is out of the ordinary. Enjoy your first of probably numerous suppressors!

And, if you are shooting supersonic ammo, wear hearing protection.

 

[BurtG]

Flow cans are loud. The biggest pro for them is reducing back pressure on semi autos.

 

[Rob01]

Bluedog pretty much covered the questions. I don’t find the overbore being much of an issue though as I have used a .338 can on everything from .223 to .30 and you can’t really tell much difference at the shooter for sound. Shooting supersonic you get that crack no matter what. Shift is what it is. Semi autos are louder. Part of the game. How dirty was the brass when it came out? Just wondering how good the flow through worked.

I have a HuxWrx 36 certified a couple days ago so hopefully it will be approved this week and I can give it a try on my rifles and PCC.

 

[BurtG]

To re iterate.

No supersonic round is hearing safe.

Enough of us learnt that the hard way

Eh, eh, huh, what?

Hardest part with hearing is that damage is cumulative, so shooting a couple rounds suppressed without earpro each time at the range rarely leads to an immediate "Oh shit!" reaction and by the time it's something that can be actively noticed, there's no fixing it. Nothing like realising the cymbals or piano in a favorite song didn't just disappear, you just can't hear then any more.

Convincing people of that (and that auditory exclusion when adrenaline is going doesn't preclude severe hearing damage, you just don't notice it until later) is a bitch.

who gaf about music. Voices. People talking. Especially chicks when you’re single.

But after being married it’s helpful at times

More than that, many who buy their first suppressor have unreasonable expectations of what a suppressor actually does. I blame the 80s TV show The Equalizer for this. Regardless, “wear ear pro” is one of those things that can’t be said often enough.

Kinda like;

“Don’t marry a stripper.”

Or

“Don’t buy a car from the lot next to the base…”

10000%! None are movie/TV quiet. Always wear ears.

I got one that would change your mind

But FFS, wear ear pro with supers. Even as tough as you think you are

Not talking about Rimfire cans or subsonics.

Still not a rifle.

 

[roostercogburn98]

Technically a rifle (sbr), but a pistol caliber. I’ll see my way out on this one(still skeery quiet)

Yup you win. All cans are movie quiet

 

[roostercogburn98]

Better than this statement I guess. One has to be true

 

[roostercogburn98]

And I was seeing my way out cause you said not rimfire or subs. Technically all 45 acp is sub except some niche rounds, but I agree with centerfire rifles being loud even suppressed

 

[Rob01]

We are talking about rifle calibers and in ARs. Go read his original post again and then maybe again.

Having hearing damage does blow let me tell you. BUT, cans are starting to change, slowly. I've fired two, believe it or not, that were indeed, at least to me, hearing safe. And they're getting better still.

The crack is not.


^ why I re iterate


I have 338 ultras etc. GFL finding quieter

 

[Basic user]

I had a fired a can overseas that had wipes. We filled it with shaving cream, and that rifle was quiet as fuck. Of course that only lasted a few rounds but still. Very impressive.

 

[joetuono]

I personally don’t find shooting 300 blk subs out of a semiautomatic to be comfortable to my right ear. Tried it with both 30 Nomad and Sandman X. After 5 shots my ear noticeably hurt. Isn’t just the action cycling on an AR around 125 or 130 db?

Getting back to supersonic rounds, does the supersonic “crack” happen as soon as the bullet exits the suppressor or is it further down range?

 

[DemonicLemming]

The crack is not.

Yep. Can't beat physics, and physics says something breaking the sound barrier is going to be loud. The first time I shot an AR with my Sandman-S and no earpro was the same time I decided that a suppressed supersonic 11.5" 5.56 wasn't the answer for home defense rifle, a suppressed subs-only 300BO was (and even that is still relatively loud).

 

[BurtG]

I’ve shot a few things.

300subs are less than impressive. I’d go super 300s or 556 first. Barnes black tip 300 is impressive I hear

I know 556 77tmks are shockingly deadly

Yeah it's definitely not my first choice but I'm trying (ha) to mitigate that some by handloading and using monos. SubX is junk, basic bitch JHP with a clit mouse shoved into the end to make it look pretty or something, fuck if it helps terminal ballistics (least not that I saw on deer).

77TMKs are horrid little things on meat but they're damned hard to find. I have some 73 ELD-M loaded up hoping they'll be similar enough for now.

 

[Basic user]

I guess it can also depend on which cans you have experience with. I have a dead air nomad 30, a yankee hill turbo k, old gemtech M4-SD, OCM5, aac jaeger 30, q half nelson, a form 1 556 can, form 1 308 can, and a CGS mod9sk and they're not even close. The aac jaeger and the q cans are LIGHT YEARS quieter than the rest. I mean a whole nother league. The rest of them KIND of quiet down the report, while the OCM 556 and cgs 9mm cans do ABSOLUTELY NOTHING whatsoever. Literally it's like I dont even have a can on at all. So, it does highly depend on the makers philosophy when they designed the tube and baffle geometry. Some like SOME suppression but with some first round pop elimination. Some like durability and reducing sparking/flash etc etc.

I can shoot my jaeger30 or q can with full power 6.5cm stuff all day with no ear pro on and it's comfortable. The others not so much.

 

[alamo5000]

I am not familiar with the specifics of the can that the OP bought but if there is a larger than normal shift on a particular rifle it's worth checking the mounting device (if applicable).

Even very small things can cause massive differences.

One guy I know of was getting like 12" to the right POI shift so I said the same thing to him. Turns out the muzzle device wasn't mounted exactly right. They removed everything, cleaned the threads and shoulders of the barrel and reinstalled it to then only get about an inch POI shift with the exact same rifle.
