I've been curious about what's going on inside this thing since I saw pictures of it last year. They just posted some new stuff to their FB page:

It looks awesome. Very aggressive, which is sometimes needed.

Just because you can, doesnt mean you should...
I'm interested in hearing how it actually performs. |

The article also mentions lower back pressure with semi autos. Seeing how it supposedly redirects the gas downward into that lower expansion chamber area might be some truth to that. As always when they are out in the wild and some real world independent testing can be done with guys like NFA Review and MAC etc......... if the claims are proven true then fugly for the win. Function over form always if the thing works like advertised.

Better, meaning more believable, than the absurd claims of Jesse Douchecanoe James Firearms.

Looks like another "flow through" design such as the Helix from OSS.
The center of the can is just a hollow tube. The gas goes to the outside of the tube and passes over many small machined ridges. Then is free to exit out the front. There is little back pressure because the can let's all the gas flow out the open front of the can. https://m.youtube.com/watch?v=cY1r5a_SZBc |

Is that a maze of expansion chambers underneath that ultimately vents out in the front?

Yes--they are joining others who are following OSS's lead and trying to figure out how to redirect the gases instead of simply trapping them. At this point I think it's established by multiple companies and designs that this approach can lower ear levels compared to conventional baffles. View Quote The notion that you have to accept high muzzle SPL to get acceptable at-ear numbers is hogwash. It's just the paradigm for science-fiction-come-to-life designs like this thing. Conventional baffle cans are perfectly capable of producing hearing safe SPL at mil std muzzle position and shooter's ear. I'd put down $100 that the cheap YHM Turbo has better performance on both ends than this thing. |

View Quote I bet if this suppressor blocked off the port to the under side labyrinth, both the back pressure and the muzzle numbers would change insignificantly. Simple reflex chambers do a good job of reducing back pressure, mainly because the annular volume sees less resistance to 'flow' (actually more like pressure capacitance or an air spring) than the more restricted muzzle orifice and barrel-conduit. With designs like this there is a race condition between gas pressure dropping through the labyrinth and out the front diffuser, and simply back-spilling through the bore when the action opens. The slower the action, the better this will sound, but adjustable gas blocks already do that for blast enveloping designs. I'm sure it has some benefit, but that's a lot of metal and mass for what are probably minimal gains. I think a better implementation of these concepts (pressure drop of gases whose flow is already moving off the bore line and dispersion through front diffusers) is the Delta P .50 cal suppressor. |

The cute labyrinth beneath the can will never get fed. The gas is going to go through the hole in the baffle/ path of least resistance.

I thought it may be good to show some video of this thing in action, I wasn't aware of this thread until someone told me about it. Yes it works. The video shows that we are able to divert the majority of the gases thru the ducts as opposed to following the bullet thru the exit opening.

.338 Lapua Magnum is not what I prefer to take to the range but I have it for testing the designs. Ammunition used was handloads of 285gr Hornady ELD-M over 90.5gr of IMR 7977 that ran 2667fps on that day. |

You mentioned other calibers--will you be telling us what kind of numbers you got, or was it just part of your R&D?

On that day I also metered our non-Ugly designs. They have a more traditional shape but have complex baffle designs that only additive manufacturing can produce. They weather was not cooperating so we setup for measuring at the shooter's location and not the Mil spec testing configuration. So please keep in mind that these are not mil-spec ratings but should be within 2 or 3dB of the mil-spec values. Here's a summary of the 4 baffle configurations. Values are averages.
Config 1 .223 Rem AR 18" barrel: 144dB .223 Bolt gun 20" Barrel: 129dB .223 Bolt gun 24: barrel: 128dB 6x47Lapua Bolt gun 28" barrel: 128dB, For reference my Thunderbeast 30P-1 metered at 130dB and the sound was very comparable to my friend's ultra 9. I didn't meter the ultra 9 because I couldn't put it on any of these host guns for direct comparison. Config 2 .223 AR 18" Barrel: 143dB .223 Bolt gun 24" barrel: 126dB Config 3 .223 AR 18" Barrel: 144dB .223 Bolt gun 24" barrel: 125dB Config 4 .223 AR 18" Barrel: 144dB .223 Bolt gun 24" barrel: 127dB It appears that the meter was registering something in the action, probably the bolt slamming. Mil spec testing may actually produce significantly lower values due to the fact that the meter will be place further away from the cycling of the bolt carrier. |
|
There's a lot of variability/noise in that data but then again real world action noise, different powder pressure-time curves, atmospheric and environmental conditions and reflective surfaces are a real thing. If 2" of barrel is that effective a small increase in blast chamber volume would also help but I'd guess you've already tested that response sensitivity. More than likely gas system dwell time and bolt speed are the independent variables affecting your measurements.
Have you tried blocking off your diffuser/capacitance section to optimize the blast-forward stack? |

Just a clarification on the reported test data. Each configuration is a different design, primarily different baffle designs in the same outer body to determine which baffles work better. The different baffle designs handle gas flow in completely different ways. The variability in the data is more the differences in designs and platforms. The reported dBs are averages of five readings and most had an extreme spread of ~3dB or less for each set.
I will be releasing more Ugly data in upcoming weeks, if the torrential rain ever stops long enough to get set up for mil-spec metering. The Ugly design is tailored more for applications that make other attributes higher priority than ultimate sound reduction. The shortened length and shifted center of gravity can be more important to those that may be clearing buildings, holding the weapon up for long periods of time, want lower operating temps, etc. So the Ugly design does reduce sound but admittedly it doesn't reduce sound as much as someone like Thunderbeast or other reputable brand. It does give other benefits for certain users however. I use the Ugly 338 every time I take the .338 to the range because it works very well (check some of Ray's Thunderbeast 338 videos for reference) and doesn't protrude 11"+ from the already long barrel. And that gun is unbearable to be around without one. https://www.youtube.com/watch?v=BkL25aG2sbI&feature=youtu.be Ugly 338 Side view slow motion |
