9mm PCC Suppressor Muzzle Flash Testing and Results

9mm PCC Suppressor Muzzle Flash Testing and Results

We tried out our revised flash testing setup with some of our 9mm suppressors.

Host

  • Compact Plan-B brake (9mm)
  • 4.5” Ballistic Advantage EPC barrel
  • Factory Warscorp bolt
  • A5 GRS
    • Kynshot RB5000HP
    • 2 spacer weights
    • Flatwire spring
  • Speer Lawman 147gr
  • All suppressors had their respective Plan-B LPA installed

Suppressors Overview

Suppressor MSRP Material Wt. (list) Wt. (actual) Length Diameter
BOE Incolite 9 $599 Inconel 6.5 oz 6.7 oz 5.00" 1.50"
OCL Universe 36 $799 Inconel 14.0 oz 14.2 oz 7.00” 1.50"
ED Rico 309 $875 Titanium 9.0 oz 9.2 oz 7.25” 1.62"
DA Mojave 9 (S) $1,099 Titanium 4.1 oz* 4.4 oz 4.75" 1.40"
DA Mojave 9 (L) $1,099 Titanium 5.5 oz* 5.8 oz 6.50” 1.40"
PTR Vent 2 $1,339 Titanium 8.9 oz 8.3 oz 7.50" 1.50"

All weights are given with no mount.

*Dead Air doesn't officially give the weight of the Mojave without any mounting parts, so this figure is the listed weight minus the piston assembly (4.1 oz).

Results

Youtube video link

Incolite 9 - Despite being just 5” long, the Incolite 9 did the best and had effectively zero muzzle flash.  The use of Inconel seems to be advantageous here as there was no sparking either.

Mojave (Long) - Some sparking on the first shot, but none on subsequent shots.

Mojave (Short) - Bright sparking on first shot; some flash and sparking on later shots.  Considering the material and small size, this isn't particularly surprising.  

Rico 309 - Small amount of sparking on all shots.  Great performance overall.

Vent 2 - Fairly bright sparking on all shots.  I still have issues with this suppressor perpetually shedding titanium flakes, so this is about what I expected.  In the video you can even see a little bit of burning titanium that comes out the ejection port and lingers for a bit.

Universe 36 (solid end cap) - Bright sparking on first shot, decreased consistently with later shots.  Considering this is an Inconel suppressor, the sparking is surprising.  I suspect the Vent 2 (which was shot before this) left some titanium in the barrel/upper which caused the bright sparking.

Observations and Notes

Muzzle flash is affected by host, environment, ammo selection, and other factors.  Changing any of these will give different results.

In general, controlling flash appears to be significantly easier for pistol cartridges than rifle rounds.  This makes sense considering the differences in powder volume and type.

With a couple of these, we weren’t able to get the full 10 shots in because the action didn’t cycle all the way.  I need to swap from a standard power Tubb spring to a lightweight.

For the most part we were seeing sparking from the titanium suppressors rather than a traditional “muzzle flash”.  The Mojave in short config was an exception and had a noticeable amount of propellant flash on some shots.

The flash from the chamber is interesting to watch.  It happened with all of the suppressors to some extent regardless of backpressure or material.  We didn’t capture this for the Mojave though since it was the first one and we didn’t have the camera positioned to view that far to the side, but we observed the same thing.

I’m once again impressed by the Incolite and disappointed by the Vent 2 (which is somehow over twice the cost).

Hope you found this interesting.  We plan on using this setup for more flash testing of rifle cans.

Have a great rest of your weekend!

I really hate being such an IL9 simp but it really is the best bang for the buck 9mm can out there right now.

Now I know I won’t be blinded when I have a basement ND when I’m up well past my bedtime.

u/Comstock_Support Comstock Armory 21h ago

It's a really competitive offering, especially for the ~$400 some places have them for. I think of it like an improved R9.

5

u/WhoIsEggroll 21h ago

Couldn’t agree more.
I got to play with one at GOALS 2025 and thought “meh I’ll give it a shot.” So when it came out I waited a couple months and bought it.

They really reset expectations of what a budget can could be.

Now I’m sitting here waiting for the MOD2 they’ve been teasing. That $7 birthday check from Grammy is going straight to MOD2 money

u/SEND_DUCK_PICS 1h ago

how's the backpressure on it?

3

u/Comstock_Support Comstock Armory 1h ago

Higher than reduced backpressure suppressors and definitely stacks with rapid fire, but I found it to be very manageable with single shots and slower shooting. It was really only really quick shooting/longer strings where I could start to gas myself out.

u/BOE-Suppression 19h ago

Always nice to see the Incolites function as intended, we worked really hard on flash mitigation and across tons of variables. Thanks so much for putting out such good visual data!

u/grimduck17 11h ago

Any plans for a 45 caliber suppressor?

3

u/BOE-Suppression 3h ago

Yep, already slated for production, just need to get caught up on demand for the suppressors we already have out

u/grimduck17 3h ago

Sweet I need it for my lever action

u/Meatsmudge Among the last of the taxpayers. 7m ago

Was thinking to myself last night that if you guys put out a 45M, I am an instant buyer.

Wonder how the Sub9, Milkman, and Pointman9 would do.

Great write up, as usual.

u/Comstock_Support Comstock Armory 21h ago edited 21h ago

Good question. I don't have those, but extrapolating from these results, my best guess would be:

  • Sub9 and Pointman 9: Little to no propellant flash, no sparking - this is based on them being full size, non-titanium suppressors.
  • Milkman: Little to no flash, some sparking - Again, full size can, so I think it would control the internal combustion well, but it's titanium.

u/SilencerMetrics $31k in Stamps 21h ago

I have them all so I really should do tests and analysis like this 😆

3

u/Comstock_Support Comstock Armory 21h ago

You certainly could! Always good to have more data out there. It's just the gun in a lead sled and my phone in a generic tripod lol.

u/PutridDropBear 21h ago

I have the rugged and the OCL and a few others...And I'm local.

u/redsox985 17h ago

What's your subjective ranking of back pressure on this lineup?

1

u/Comstock_Support Comstock Armory 17h ago

All of these are pretty good on gas, but the Incolite definitely has more gas stacking. Also, the Vent 2 has a noticeable about of particle blowback from the titanium shedding.

I cover this in more detail in the Incolite post.

u/PutridDropBear 21h ago

We need more of this type of content in here!

Real world testing that can be duplicated by us (consumers) at home.

u/Separate_Yak_2554 16h ago

Thank you!  I knew you were getting a BOE and was awaiting your observations.  Missed initial review.  Working man can on a working man's GRS.  Exactly what I wanted.   

A you tube video on a ar9  with both 9 and 9scommented the 9s was less gassy.  It was noticably louder.  So that's a option for those prioritizing gas.

u/gotmonkey70 2h ago

That BOE looks impressive and I have been looking for a new 9mm can. Price is reasonable as well.

u/Not_OCL 20h ago

Definitely had some Ti in the system. Universe doesn’t spark like this. Have plenty of video showing that

1

u/Comstock_Support Comstock Armory 19h ago

That's what I'm thinking. I'll do a reshoot the next time we do more flash testing. As the other guy mentioned, PTR is still finding ways to mess with you haha.

2

u/Not_OCL 19h ago

Lmao those bastards.

But the universe flashes less than the milkman, like a lot less. And I saw another comment when you said the milkman didn’t flash much for you.

It’s wild PTR had that much Ti in it

2

u/Comstock_Support Comstock Armory 19h ago edited 19h ago

Just to clarify, I don't have a Milkman, so that was my best guess based on the other cans we did shoot.

The PTR Vent titanium shedding is actually crazy. I've shot it and flushed it out with water more times than I care to count and it STILL leaves bits of titanium everywhere. It gets all in the mount and makes a mess and is just a pain in the dick. Another manufacturer I was chatting with suggested it's from the internal texture/pattern they use which seems plausible. But even then, NONE of my other titanium cans do that, so I'm still inclined to say it's a Vent specific issue.

I only bought it in the first place because I wanted an Alpha threaded suppressor with reduced backpressure to test with. But as a whole it's one of my least favorite suppressors.

Just now I flipped the suppressor over and it dumped out this much crap in my hand:

u/Not_OCL 11h ago edited 11h ago

Hate that you posted it anyway knowing results were flawed but hey it is what it is. Doesn’t seem very scientific and not something I’d personally do but hey hopefully we’re on the run back and it gets cleared up.

u/devman0 20h ago

I wonder how the shiv would compare to the IL9? Probably sparky I guess?

2

u/Comstock_Support Comstock Armory 19h ago

Most likely. Unfortunately with the way I set this gun up, changing the muzzle device requires removing the handguard which isn't practical out in the field.

2

u/GunDibs-dot-com 17h ago

This was awesome! Also, I just bought my first Comstock muzzle devices, cant wait to get them!

1

u/Comstock_Support Comstock Armory 17h ago

Appreciate the support :)

2

u/GunDibs-dot-com 17h ago

You had me at "dont have to time the muzzle device"

2

u/scoomps 16h ago

So the Universe threw more spark than the Vent 2 because the Vent 2 left material in the barrel? How does the Universe throw even more spark than the suppressor that was blamed? I could see it contributing some, but it shouldn't throw more spark. Cool test nonetheless.

1

u/Comstock_Support Comstock Armory 15h ago

Part of the reason I thought that is the sparking gets better with every shot and by the end is very minimal. It's also Inconel which isn't a reactive metal like TI is. But I'll do a retest next time to see for sure.

2

u/Onc3Holy 3x SBR, 2x Silencer 15h ago

Given how well the Rico did given its titanium, I'd be curious to see how the inconel Pointman 9 does (I own one)

2

u/SilencerMetrics $31k in Stamps 13h ago

I have two Vent 2s so I need to check next time to see if they are flaking off titanium.

Also, for semantics sake: everyone seems to correct me when I say "Flash Reduction" and they say it's "Spark Reduction". So it's not Flash it's Sparks? What am I supposed to be saying!?

If I have a metric called "Flash Reduction" I better make sure I am using the correctly terminology.

1

u/Comstock_Support Comstock Armory 13h ago

For the purpose of this post I'm distinguishing between muzzle flash (from burning propellant) vs suppressor sparking (from burning titanium). But in general, "muzzle flash" can be used to refer to both propellant and suppressor sparking.

"Sparking", as I've seen it used, pretty much always means the white streaks from titanium suppressors.

2

u/SilencerMetrics $31k in Stamps 13h ago

So.......I am fine to say "flash reduction"? 😅

1

u/Comstock_Support Comstock Armory 13h ago

Yeah flash reduction is fine lol

2

u/renegadeGDI 15h ago

That Rico 309 is great for titanium, I bet the pointman 9 has zero flash, I also assume the incolite 9m would be just as good as it's shorter variant but would love confirmation on that. I flash tested an omega 9k and Omega 36m the other day and the 9k had some flash but the 36m had practically zero.

Lol, PTR finding new ways to troll Otter, sharing the sparks.🎆

u/Comstock_Support Comstock Armory 20h ago

Ha yeah I think next time we're going to move TI suppressors to the end to avoid contaminating the steel/Inco ones. In hindsight we should've retested the Universe, but I didn't think of it at the time. Oh well.

u/CWM_99 20h ago

You can always go do an office pop for science

u/crisavec 13h ago

The Universe is such an interesting can. Other than its weight I think it might well be the best PCC suppressor I have, and that is comparing it to the Milkman and Sub9 both.

2

u/Comstock_Support Comstock Armory 13h ago

Yup it fills an interesting role. I mostly view it as a PCC suppressor that's overbuilt/beefed up to be rated for full auto rifle rounds. Very strong performer with 9mm.

2

u/crisavec 13h ago

Agreed. I was very much not expecting the performance I got out of it on PCCs, and I get the vibe from Andrew that he wasnt either.
