UM/S2H/Suppressors/Scopes and More!

It's a .30 cal can. So it's going to be overbored likely close to .35-.36, if not a little more. Not an issue, IMO. I've built Form 1 cans where the tolerances are a lot less due to "cups" dropped down a "sleeve", that are not a perfect tight fit. Never had a baffle strike.

Any 3D printed item will come out looking rougher than something that is CNC machined. It’s the nature of the beast. It’s essentially built up by MIG welding titanium powder. I’m sure UM/US does a qc check before they go out the door so that nobody is anywhere close to a baffle strike.

After a hundred rounds or maybe a few hundred, my guess is that the inside of any can would look much the same due to carbon buildup.

Screw it on, shoot it, let everyone here know how it sounds & balances. If you’re more concerned with how it looks inside, feel free to take a round diamond rasp to it. It’ll likely void the warranty, but please report back on that also.

(That last part was lighthearted sarcasm, don’t run a rasp down your suppressor)

Yeah if you look at all the other printed cans they look the same. Look cheap on the inside but seem to perform pretty dang good.

Picked mine up today. I promptly weighed it 10.9 ounces. I alsoe ran a borescope through it... Interesting texture in there. Looks like it will definately hold onto some carbon... I'm not going to post the video to avoid giving away any trade secrets... View attachment 893450

I did notice three equiadistant proud spots in the bore area. I'm shooting this exclusively on a 6mm but might be worried if I were to put it on a 30 cal.

Put the bore scope down and shoot it- it is a 3d printed can, it’s fine.

The rough texture will increase the rate of heat transfer (and may contribute some damping at higher frequencies).

To clarify, I’m not worried about how it looks inside, simply was curious and I know others who were as well. I understand the nature of 3D printed Titanium.

I was surprised there are visible high spots and the bore isn’t concentric in a few places. When you look down the bore they are quite obvious. Seems like a simple fix would be a final machining step to clean it up further.

I will absolutely shoot it and reach out directly to US if there are issues… which I don’t expect to need to do.

Those last two photos look like some kind of tooling got run down the bore -- or is it just ridiculous amounts of light?

@Unknown Suppressors I'm sure you have considered this idea and maybe it's not something most would buy, but I would love to see something like this. For those of us who only shoot suppressed having a barrel threaded this way with a suppressor like this seems like it would be the lightest weight quietest(most volume) option. Excuse my bad handwriting lol.

That's an awesome idea!!

I sent it to form awhile back but it didn't sound extremely promising. A guy can hope though .

There is a flashlight on the other end... There does not appear to be any machining in the bore itself other than the threads and the shoulder. The high spot in the bore look like they are from the 3D printing process.

Shooting it today.

Great customer service for something that looks like horrible quality control. You can see those high spots with the naked eye- no bore scope needed

Tip of the hat for Unknown communicating on a public forum answering questions and being transparent. It’s a gift being able to do that when so many people are more interested in looks than function. The inside of a suppressor slight imperfections in the finish of synthetic stocks and I can’t imagine trying to match all the color coordinated accessories with the perfect shade of cerakote.

You do realize he wasn’t talking about the proud spots just because of the visual look correct? It was because of the concern of having bullet contact with a larger bore rifle

I have full confidence that they allow for that. If I remember correctly one of the test they ran was with a 33 caliber although it’s a 30 caliber can. I’m sure it has plenty of clearance. If I’m wrong I’ll immediately apologize and my confidence will change in QC. Until then I’m going to trust they know what they’re doing and not worry about a problem that hasn’t happened.

 

[JBahr]

Pretty sure they drilled out the can for the 33 test.

That could very well be the case. I could also be overly confident in people I’ve never met. Mine shows delivery for today so I should get it in a few days or weeks who knows? Haha. I will shoot it through a 20” 300win as soon as I get it. One reason is for this and my curiosity about how it will perform on that rifle versus what I currently have.

Yours shooting fine with a 300 win doesn’t mean the next one does- I don’t think he was saying that every suppressor has high spots- he was just saying that his did- I doubt every one of them that leaves has high ridges in it- they aren’t intentionally doing that- that was something that happened in the printing processes. I agree a post manufacturing step to make the bore hole concentric would go a long ways

He is not customer service, nor does he work for the company; he and I have just shot hundreds of these suppressors. 3D-printed cans are wild and different; they all look much rougher inside. Some of that titanium will break off the first few shots, and you might even see sparks from molten titanium sand. This is all normal with 3D-printed suppressors.

@JBahr, from what I have seen, I wouldn't have any issue shooting a 30 cal through that can.

Of course not but it will proof mine. If I have a problem I have no doubt it will be made right asap. That’s all anyone can do. Get it shoot it and not worry about hypothetical problems until we have one.
