Unknown suppressors OG testing

[Dioni A]

I received one of the prototype suppressors to test out and give my feedback on. Figured I’d make a thread and post updates as I go.
I’ll primarily be using this on creedmoor based cartridges but will get some 6.5 prc through it as well.

My first impressions are very positive. I compared it to 3 other cans and plan on running it next to more as I go. It’s appreciably quieter than the other cans I had out. They were a JK Armament 155 configured to the same past the barrel length, PWS BDE556 in its longest configuration and a AB suppressors A10 30 cal.
I’ll try and get it next to a friends AB Raptor 8 because I think that would be a very good comparison. That can was my previous favorite for tone and suppression and I think this one will be as good in a shorter overall package.

I also really liked how the end cap didn’t have some silly design that made it impossible to get tape to seal over the hole.

Looking forward to the comparison with the Raptor 8-stack and a reflex.

Is your prototype a 30 cal can like the OG unknown suppressors is releasing soon?

 

[Halligan]

Following, very interested in the comparison to the two AB’s

 

[Dioni A]

Just checked the weight on it.

Yes it is. As far as I know this is at this point it’s identical to what they’re planning to release. I think the production models are going to be coming with some kind of a coating though.

Can you tell us what barrel diameter it will fit over?

From an email they sent out:

 

[Sundodger]

Is there going to be a tool/wrench flat/etc. on the end to be able to torque this suppressor to the barrel with a torque wrench, or is the assembly procedure more of a hand tighten thing?

I talked with @Formidilosus about this yesterday. Ideally you get it as tight as you can get it by hand with clean dry threads. The can has good texture and if you ever needed to should easily be removed with a strap wrench.

They wanted to avoid wrench flats because some people would inevitably over tighten and damage it. Even if it were to carbon lock itself on (this is a good thing until you want to remove it) you should be able to get it off with a strap wrench.

Little surprised by the dry thread approach, there are some pretty good high temp anti seize products out there these days that should work well.

I haven't thought too much about this joint, but it should be quite stiff, but now that I think about it the D/L ratio is probably not great.

Do you currently use stuff with your current cans? I don't, I was under the impression most others run them dry also.

Anything on suppressor threads just attracts more carbon and becomes gum.

This would be a great 6CM can. I'll wait for ver2 of this can that has a directional brake on it for my 7prc.

Stainless and Titanium are both prone to galling so running that interface dry has its risks. I personally run a small smackeral of lube on there but that's just the paranoid machinist in me. And for what its worth I have seen someone gall their can to their rifle... but it's everyone's personal choice what they do.

 

[Sundodger]

I have minimal experience with suppressors, so I was thinking more from a joint robustness perspective off the top of my head.

Great point on contamination, but I was actually thinking about using anti seize not necessarily for the disassembly (it's a nice bonus), but for reducing the scatter of the tq to tension relationship so the joint is less likely to come apart. Now that I look at the cutaway more closely the D/L is so non existent this is kind of a mute point. Even though I can't imagine much axial loading in service, there isn't anywhere to get "fastener" elongation.

Curious what those would sound like on a 18-20 6.5 or 7 prc? Will this be on par with a scythe? They keep saying this is designed for 308/creed based cartridges. Anyone have any insight or db numbers for comparison?

 

[RockAndSage]

Nice review, thanks for sharing. Expecting to order one they day they're released, and would like it in that color - do you know if that's the "raw" or the "bead blasted" variant?

I guess that's another reason not to have wrench flats on it and instead check to make sure it's still tight before you shoot every time. Reduce the chance of galling by making it tougher for users to apply higher sliding forces.

As much as I love titanium as a material, I hate how much it loves to gall. Hopefully they are paying close attention to surface finish and hardness if they aren't going to use lube or dry films.

The explanation I got for why anti sieze can be problematic is that it makes it too easy for the suppressor to work loose. In a perfect world suppressors would be left hand thread and would self tighten from vibration and rotational forces from the gas. Especially since these are being hand tightened and not getting into the elastic range of the components which typically holds bolts together.
The next best option is clean threads. If your concerned about galling you could use something like olive oil that will burn off.
Again I’m not an expert in this but all of this was recently explained to me and seems to make sense.
