I have the OSS Elite 7.62 which is not made any more. It is the two piece over the barrel model. I imagine the Helix would have similar results. It sits on my 14.5 inch 300 blk XCR-L. I bought the suppressor for the flow through technology. It is the only suppressor I have ever shot so I cannot really compare it to others, but it works for me. I rarely take if off. there have been two occasions when I forgot my shooting glasses when shooting the gun, and I never noticed the blowback at all, although my eyes were quite irritated after I got home. Overall, I am impressed with the technology. The only negatives were the price at the time and the weight seems a bit heavy at 30 oz. After I bought mine in 2017, the company went through some major management changes and disruption by firing the original designer. Just make sure they have their act together so they will service your can should anything happen to it. I doubt they would be able to service mine since the line was dropped.

You are absolutely fine my man! Yeah the new sigs are metal printed titanium or inconel. I haven't been given any info on them yet other than whats available to the general consumer so i can't say whether they are fa rated or not officially but their videos shows it on the new ngw program belt fed (in the new 6.8 which is substantially hotter than 308) so i'm assuming eventually they will come out and say yes. For comparison, the TDS printed cans are belt rated and no minimum barrel length. They show theirs on a 12" FAL which would destroy most cans. They claimed you would melt the barrel before you could melt the suppressor because of the properties of inconel (i think they put more nickel in it or something like that?) having a higher melting point. Sooooo if the sig's are even similar inconel there won't be anything out there in the category its designed for that can hurt it. My biggest draw was the accomplishment of designing and making a can that has LESS blowback than a rifle WITHOUT a can. That's impressive in my book. Along with that they say the new blackout specific can (which can run any 308 but its internally designed for blk) is 4 decibels quieter than the previous srd762ti that was (unofficially) the quietest 300blk setup thats ever been made. Now i dont have a db meter but to my ears its noticeably quieter so id say their claim is substantiated. At least to MY ears it is. Very impressive. I had to go out of town for my other job so i didn't get hardly any time with it and didn't shoot it fa but when i get back in a few weeks thats my plan. Making a video comparing the cyclic rate without, with old, and with new. Should be interesting. I did one a while back with the TDS so i want to replicate it with the new sig designs now. I'll see it i can link that video its pretty cool. I had another guy split screen it and set the timing the same in slow motion and you can see the backpressure differences easily.

Heres the video, i just reposted it as im not computer savvy: Facebook

If you're better with tech feel free to snag it and post it within a post so others can enjoy, and wait for part two after i get home....

Have a great night!
Nah....I sux at tech. Don't even have a cell phone. And my hearing is shot (pardon the pun) from years of grinding and shooting so I unfortunately probably couldn't tell the difference in 4 db. :(

Sounds very promising though for the Sig cans. Very interested to see the pricing once they are widely available. Thanks for the info and the link. I'll definitely check it out.

I have 2....both .308 cans....rated for full auto and out of any length bbl. I bought through a local gun dealer that sells suppressors. They aren't super quiet....but are hearing safe.

I really like them....I wish there was a standardized QD setup for ALL suppressors. I really like the brakes I have and none of the suppressor manufacturers make a very good balanced brake in terms of size to recoil reduction, so direct thread is fine for me. Would like the option of QD though....but not in love with any of the suppressor makers brakes.
Have you checked out Griffin Armaments Taper Mount muzzle Brakes? A lot of choices and the system I switched to.

Yeah, I actually have one of their tapered hammer comps. Doesn't fit any of my cans though so wouldn't be using it for those.

You can have mounts made for your cans it doesn't fit. I am having the Griffin Plan A Taper mount made for my 3 Crux cans. They also make Taper Mount Adapters in industry standard thread interfaces like 1.375x24, 1.12"x28 and interface for Dead Air Wolfman, Wolf-9SD and Ghost suppressors.

Who makes the adapter mounts? Do they have a website?

Not really loving any of the current QD brakes anyway though....compared to the VG6 Gammas I run on most guns.

Ecco Machine and Fabrication said it would be a 2-3 week turn around for all 3 Plan A Taper mount Adapters for my Crux cans so I can use any of Griffins 10 different muzzle devices.
Thanks. I'll check them out.

Hello all. I have an update on the sig slh cans (I’m more interested in the slh, not the slx but one of those was similar to the results below also). I got a few in to try and I’m impressed. First the weight. The qd300blk version including the muzzle brake was only 1oz heavier than the old srd direct thread can (the gold standard for 300blk). As for their claim of less “back pressure”, it’s very noticeable. I had to turn UP the gas setting on the xcr to run the same Ammo as without the can. It actually reduced the dwell time a substantial amount. I really thought it was all hype. To test this theory further I tried it on my 6.75” Mcx that the old srd762ti resides on full time. I shoot specific reloads for 300 Blk. 220 and 245 subs, each with just enough pressure to cycle the Mcx action suppressed. It would not lock back on last round and felt sluggish with the slh300ti can. Again reinforcing the less “blowback”. I have to say I have a new favorite. As with anything there are negatives. The price, and the sparking even though it’s minimal. Now to be fair titanium cans always spark way more when new. And I only ran one mag in the shop because I was too lazy to go out in the crap weather. In the end, for me, the weight and reduced dwell time (always incorrectly called pressure) outweighs the minor sparking. If I’m shooting at night I won’t care if someone can see them. And I can always go with the inconel version. I tried that also with the same results. No sparks at all, Just felt heavier to me. If anything changes as I play with them more I’ll let everyone know.

@SheffieldTactical Do you know if Sig is giving a round count for their new SLH/SLX cans? My BiL is looking into flow through cans and I was pushing him toward them after your recommendation but he's saying he found some forum where they are only good for 10K rounds? That sounds like some internet bullshit, but wanted to see if you'd heard any lifespan specs from Sig. Very limited information on from Sig on these.

Sorry didn’t see your post. New phone and notifications don’t seem to be working. The 10k round lifespan was through The new 277 machine gun. My rep said there’s no specs on that but an inconel can is an inconel can. It’ll have the same lifespan as any other flow through design and longer lifespan than a baffled can from reduced “pressure”. Hope this isn’t too late. I’m really enjoying them lately. Been shooting cheep steel x39 through the 12” xcr and I don’t have any wear at all on the first “baffle” that can be seen compared to a new one.

Thanks for the feedback.

Funny thing: Took a couple XCRs out for a night shoot a few weeks ago....both the X39 9.5" and 5.56 9.5" both gassed me in the face like I've never experienced before. It wasn't so bad I had to stop, but it was noticeable. Wonder if it was the temperature (in the 40's). The ammo was Barnaul I'd never purchased/shot before for the .223 (steel poly-coat which I normally avoid, having had issues in the past...but it was cheap and available at my LGS). The 7.62x39 was Wolf made by Barnaul....and I've shot a ton of this. Only got gassed in my one AK (M92) with this ammo....Ah...just remembered though: I was trying out my new X39 9.5" bbl (instead of the original 9" I had....changed b/c you had to remove the bbl to install a can). I wonder how a difference in bbls might result in more gas in the face, if it was temp related, gas setting related (too dark to dial down since I couldn't see the ejection pattern), the ammo in question or something else. I only mention it here b/c Northern is looking for a flow through can to avoid the gas in the face thing. I'm going to shoot with a can this coming weekend at night too....though the temp should be much warmer according to the forecast....same ammo though.

No worries. I appreciate the info. That makes sense on the .277.

Are the new Sig flow throughs widely available yet? Also, do all have the lock collars?
They have direct thread options as well:


Scroll to the chart for SLH.

Oh, and for those that don't know....OSS has changed names....not sure the dynamics of why. They are now HUXWRX Safety Co.

EDIT From the site:

First and foremost, we want to thank all of our loyal OSS customers for the support over the years. It is because of you that we are here today. It's been an amazing journey, and we are incredibly excited for this next chapter. It's imperative that you know that you will always be supported. HUXwrx is a subsidiary of OSS Suppressors. All of your order information has been retained, and your products will remain under warranty. This is merely a new name and a new direction for the company. The same good folks will be building the same high-quality suppressors you've come to love right here in Millcreek, Utah.
Thank you again for all of the support. take a look at our FAQ below and If you have any other questions, please don't hesitate to reach out to [email protected]


From here:


I wonder if the name change and 'subsidiary' schtick is more about OSS founder and how they shafted him than anything else, but that's the cynic in me, lol.
