LR Hunting Suppressor for Accuracy / Precision

[Waterman86]

The only thunderbeast I have is the takedown 22... b/c I'm poor but I have a griffen Optimus that I run on a 24 in 308 and 6.5 out to 1025yrds. I swap it onto some AR15s occasionally too. It tightened up groups on both of the bolt guns, I leave the 308 zeroed with it now. I haven't running on the 300 prc or win mag (not enough rounds down range to play with them yet).

im trying to understand the fugly CGS Hyperion thread adapters. It looks like they would make the can stick further forward off the front of a barrel than a direct thread or say TBAC CB style adapters. Is that the case?

Yes, that's the case. You have to use them though if you don't have at least 0.735" of shoulder. It adds about 0.8" of length to the setup which IMO isn't awful, but I also am not caught up in the short barrel craze.

Some might say that you don't need to abide by CGS's recommendation of 0.735" shoulder behind the suppressor, but I'm going to listen.

Maybe 0.8" shouldn't matter to me but I already hate the extra length of a suppressor while hunting enough that I rarely use them so adding more length unnecessarily seems like a dumb mistake on CGS's part.

It's all because of this shoulder. I'm not sure why it's there, but the designer, Josh, seems to be a pretty intentional guy.

Is that still there if you buy a direct thread model?

Would be helpful if these manufacturers listed the length in the dimension that actually matters to customers - how far does it extend past your muzzle, in direct thread and QD configurations.

That shoulder is on both of the hyperion models, that's not even the thread adapter. This is the shoulder with the adapter behind it.


Edit: this is my actual rifle with the adapter

Great question. I'm in the group size camp. Looking to use can for hunting and want a can that does NOT change group size (unless it improves!).

I think this is misunderstood by a lot of people. There could be an impact to precision by running a suppressor. Most of the info says adding weight to the end of a barrel should decrease group size, but it's so rifle specific there is no way to say one can increases precision more than another across the board. When talking about suppressor precision people should be talking about repeatability when removing and replacing. Having to re-zero every time you take the can on/off is worthless.

That is where TBAC used to be the one and only gold standard. Like Form said, that part of the market has come a long way, with manufacturers and 3rd party mounting systems. So it's not as big a factor anymore. Regardless I don't think I'll own anything non-TBAC in the near future.

Anyone know a way to use the hyperion on a 1/2x28 barrel? Their adapter says only compatible with 22 cal.

They will bore that 22 adapter to 30 cal. It says that in the site.

@Formidilosus what adapter are you using to direct thread the hyperion on the factory tikka contour? Shaens flared shoulder or something else?

Pva is cutting and threading mine to 1/2-28, but the thread adapters they're offering are not really impressing me.

On a couple none. On some several different 1/2x28 to 5/8x24 adaptors. One from PVA I think, others I don’t remember. All the adaptor does is get the thread pitch correct. Screw it on, install the suppressor, make sure the bore is clear and straight through the can. That’s it.

@ResearchinStuff

The designer of the can says it needs a shoulder diameter >=0.740”. I’d listen to him.

This is from an email exchange I had with Josh Parker, the designer.

“If the threads are 5/8x24 and the barrel shoulder behind the threads is .740” or greater in diameter then the silencer will go right on. If the threads are 5/8x24 and the barrel shoulder behind the threads is less than .740” in diameter, then you need to use the 5/8x24 Hyperion Thread Adapter.”

The same would be true for any thread pitch.

That said, you can do an adapter like others have done, essentially adding shoulder. Photo from another WKR.

I’m not sure why you tagged me?

There are these adapters, too: https://www.eccomachine.net/product/sig-taper-1-2-28-to-5-8-24-adapter/

 

[ResearchinStuff]

The pva adapter has a sufficiently wide shoulder (.9+" ), is just not very thick at the shoulder, average .096". To the eyeball, the shoulder looks very susceptible to bending. I played with it a bit more last night, and it feels more solid than it looks, but I'm still not sure I trust it.

I appreciate the other link, The Ecco machine adapter looks more robust, but is now out of stock. Fortunately I've got a few months to figure this out while batf putzs around.

After some googling, what pva had looks identical to what silencer central has, so I guess it's probably fine.

Is it something they will do for you? I can't find mention of it on their site but I could be overlooking it.

Awesome thanks. Now to go drop some coin and wait for 2024

To no one I particular:


I do not care what anyone does, I do not care what you do, but this whole handwringing, skull-phuccing, endless and mindless worry of “OMG suppressor threading” is ridiculous. People on the internet with little to no experience make it seem like it’s such a big deal- it’s not. All they are doing with their “but, but, but” is making people think threadings and suppressors are a huge pain.

Stop.

With a bolt gun- get a muzzle threaded straight. If the base threading is less than your suppressor, get a threaded suppressor adaptor such as these-




Use Rokset or other thread locker, screw the adaptor on. Screw the suppressor on tight. Pull the bolt, look through the bore and ensure there is no obstruction (or use a Geissele Suppressor Alignment Rod), then go shoot. That’s it.


I am well aware of what manufacturers recommend and why. I am well aware of what CGS recommends and why- it doesn’t mean what people think it does. It is very likely that in the last 6 months alone I have shot more rounds through multiple bolt action rifles, with multiple different suppressors, with less than recommended shoulder diameter than all the “but it’s not recommended” people combined have in their lives. I have seen no less than a dozen rifles doing what I shot above with almost every can thus far mentioned shot this fall.

That's a helpful photo, thanks. The adapter on the right looks identical to what pva handed me.
