Silencer Review: Rebel Silencers SOS – Hunter

My various screeds here and on my weekly podcast should erase any doubt on where I stand on the Hearing Protection Act. Specifically, what its passage will do to the current stock of available silencers (decimate it), and what the surge in demand will do to prices (lower them, slightly). Ever the contrarian bunch, our assembled commenters have reminded me of the following:

  1. Silencers are just tubes with baffles
  2. Any competent machinist can make one
  3. There’s less than $100 of materials in a silencer

All of these facts lead our readers and commenters to believe that silencers cost WAY too much. Nevermind that street prices on durable .30 caliber cans are now down below $600 in the current marketplace. Luckily, my local dealer, Capitol Armory, has a steady supply of silencers on hand from various manufacturers eager to have their wares displayed in Capitol’s online marketplace. One such silencer is the least expensive offering on the market right now – the Rebel Silencers SOS – Hunter.

The SOS – Hunter boasts the lowest MSRP out there at $250 (before tax stamp). It’s made of 7075 aluminum and in the full baffle stack configuration adds 10 inches of length to your rifle of choice. With four baffles, a removable end cap, and a direct thread mount that is capable of accepting 5/8″-24 and 1/2″-28, it’s designed for, and appeals to, the extremely budget conscious buyer. Rebel also guarantees that the SOS – Hunter is rated for .300 Win Mag.

Initial inspection showed a roughly finished product with very visible machining marks. The threading for the baffles was on the order of what I’d expect from a high school machine shop – gritty the entire way.

Rebel says that this silencer is finished with Cerakote, but it should be apparent from the photos that they finish the silencer as a complete unit, so there’s obvious overspray and drip lines inside the baffles. The finish is even enough, but the lack of surface prep means that the Cerakote looks a little odd in places.

But hey, if it looks rough, but it works, it isn’t so bad, is it? Given the experience that Jeremy had testing an aluminum muzzle brake, I feared for my safety and elected to test the first few shots remotely. My plan was to first see if it would blow up, then do a standard test for point of impact shift. Assuming that went well, I then planned to meter it.

As you can see, it didn’t blow up. Three shots through that rest and the can was still intact so I elected to don my best safety gear, and fire it into a berm.

I finished off a magazine with seven more shots, loaded up another nine and recorded this for future use. Total round count downrange – nineteen.

After nearly twenty rounds of .308 WIN, the SOS – Hunter was still intact. On the one hand, I was sad because wanton destruction is fun and I’ve never had a can blow up on me. On the other hand, I was filled with doubt.

Maybe I’d been wrong. Perhaps I’d been in my lofty perch for too long. Perhaps the Dead Airs and SilencerCos and Thunder Beasts of the world have been overcharging for their products all this time. Then I broke the SOS-Hunter open.

On the left is the “blast baffle” which is the first baffle nearest the muzzle. There’s no defined blast baffle in the SOS Hunter so whichever one you have near the business end is the one taking superheated gasses, unburnt powder, and tiny pieces of copper jacket.

As you can see from the photo above, the “blast baffle” has already started to suffer from severe erosion and pitting after only nineteen rounds. I ended my test here because further erosion will only make for better pictures and a higher ammo bill for Farago.

Going over the rest of the baffles, they looked pretty good, and it occurred to me that the truly thrifty owner might just swap the baffle position in much the same way I rotate the tires on my truck. After some period of time — call it 200 rounds — the can could go back to Rebel where I’m sure they’d happily replace the damaged bits. Oh, what’s that? Rebel doesn’t offer a warranty. In fact, here’s their position on replacement parts.

We sell replacement baffles, end caps, and thread inserts inexpensively. Most will never need a replacement part, and unless it’s the serialized back piece (very unlikely) that you need to replace, you’ll send us the bad, and we’ll mail you out a fresh baffle or front cap.

So again, like the tires on my truck, I should be able to keep rotating them until they wear out, and then buy four new ones. But what about the front cap?

Oh look, a baffle strike. Somewhere in my limited testing, I managed to just nick the end cap. Given that I tightened the whole thing down to the muzzle tightly enough that it took a wrench to break loose — and I trust Ruger knows how to cut threads — I’m going to let this one sit in Rebel’s lap. Either the aperture on the end cap isn’t large enough or the threads aren’t cut correctly. Neither one is good.

At this point, I suspended my testing. Low round count baffle erosion and an end cap strike are enough of a reason for me to stay far far away from this silencer and encourage you to do the same. There’s no point in checking for point of impact shift with a damaged end cap, and the erosion issue is a ticking time bomb.

Ratings (out of five stars):

Fit, Finish, Build Quality: *
The SOS – Hunter has a high school shop class level of finish with obvious tool marks and threads that are roughly finished. The Cerakote isn’t applied to the baffles individually so there’s obvious overspray and drip lines. The whole thing feels cheap because it is.

Sound Attenuation: * * 
It quiets the sound enough that the ATF considers it a silencer, but firing it from from 30 feet away, it was still fairly loud. I never tried firing without hearing protection and I never got to the point of putting it on a meter.

Durability: Dumpster Fire
The Rebel is so unreliable that it makes a vintage Jaguar look like a Honda Accord. Twenty rounds of mild pressure .308 WIN from a sixteen-inch barrel and the baffles had already started to erode. And I had an end cap strike.

Overall Rating *
It meets the legal definition of a silencer. But it’s made of a substandard material that doesn’t hold up to any degree of volume shooting and it’s so poorly constructed that putting it on the end of a rifle and firing it damaged the end cap. It’s loud, cheap, and built like something a teenager would turn out in fifth period. I can think of no situation where I would encourage someone to buy this over a slightly more expensive silencer.


  1. That’s a shame.

    I think I will continue to not purchase a silencer until the NFA gets repealed (fingers crossed!).

    1. gun_ninja

      Thanks for the honest review. I appreciate candid assessments even when the news is bad.

      That said, this a bitch’s can for my mall gun. Might slap a SilencerCo sticker on the side of it. Or maybe a heat cover or whatever those cool cloth tubes that slide over can are called. When I slide my Hi Point carbine out of the back seat of my Chevy Vega, my homies will kneel. Spending too much on a can that will never be used is a bad idea. Glad these Rebels make a posing can for the rest of us.

    2. Danny Bean

      You think the baffle strike could have been when you put it on the string and it slid off the mount when firing? Really didn’t seem like much of a test… no sound test, no proper equipment for test fires, not even a visual “string fire” of the suppressor. If you haven’t seen Rebel’s videos, they’re way more informative then this. This is just another person we have to trust in what he says and not experience it with our own eyes. For the price, still going to give it a run.

    YHM – Inexpensive but good

    Go HPA !

  3. If that’s a Ruger Scout rifle, the last one of these we had did not have a good perpendicular shoulder behind the threads. The threads on our sample rifle ended at the front of the (cast?) front sight base. The sight base, at lease on the sample we had, did not provide the necessary perpendicular shoulder for properly indexing and aligning a direct thread silencer. this may have been a contributing factor in the end cap strike you observed.

      AAC – slightly m o r e expensive – but good!

      GO HPA !

      “If that’s a Ruger Scout rifle, the last one of these we had did not have a good perpendicular shoulder behind the threads.”

      Thank you, you just convinced me that having a competent ‘smith to verify the threads on every gun I may be inclined to slap a can on would be a good idea.

      And probably the threads on the ‘can as well…

  4. SilencerScott

    As much as I like suppressing my Ruger rifles, you should not trust their ability to thread a barrel for suppressor use. Check and double check your can’s alignment prior to firing for the first time. The Mini-14/30 lineup and Gunsite Scout rifles are notorious for having flash hider quality thread jobs with a shoulder that is not to suppressor spec. All of my 22/45s, 10/22s, and American’s have been threaded correctly – though I know there are people out there who have had problems with those too.

  5. Warren

    You’re not wrong about the cost of silencers. You just tend to be an a$$hole on instagram about it.

    1. Tex300BLK

      Awww, show us on the doll where the big bad guntruth hurt you… it’s ok, you’re in a safe space Warren.

  6. Bikinis&Guns&Beer

    Wait for HPA to pass. As consumers, we have no obligation to support any business or industry.

    If and when HPA passes, there will be new silencer companies to take the place of whoever went out of business.

    If HPA doesn’t pass, there will be new silencer companies to take the place of whoever went out of business.

    1. John Arnold

      …and no warranty support for the suppressors you’ve already bought.

  7. Jason

    Every 10/22 I’ve ever seen with a factory thread is threaded .200 too long.

    Ruger is not known for correct threading.

    1. Geoff PR

      “Ruger is not known for correct threading.”

      Ruger is known, however, for being no-hassle on warranty work.

      What’s Ruger’s response when notified their threading is out-of-spec?

  8. Tom in Oregon

    Been waiting on photos since you talked about this on your podcast.

    Sometimes, inexpensive is just too cheap.

  9. Alex Waits

    Do you have any other cheap supressors to test, or is this a one and done deal?

  10. Andy innOregon

    I would like to know if Rebel Silencers ever responds to your review. If they do can that get printed on your site too?

  11. Dwi23

    I’m a bored former machinist with access to a machine shop, and I have a couple bills to throw at materials, just waiting for the HPA to pass because I’ll be damned if I am going to pay 200 bucks to the ATF for the priveledge of ditching my ear pro. Seriously, silencers do not need to cost over $400 to be high quality, but for some reason enough of us are paying twice that, meaning the market has adjusted to normalize. Yes, engineering costs money, and yes, there are a lot of factors that go into pricing – but for a guy like me with the skillset and knowledge, it just doesn’t make any damn sense to buy a silencer at any price, let alone artificially inflated prices. I’m gonna wait, but that’s just my take on it.

    1. Geoff PR

      I don’t mind paying for a can, but I’ve noticed a parallel between manufacturers of higher-end bike parts and suppressors.

      Companies spend a *lot* of money on marketing and packaging. One bike company packages their stuff in glossy full-color boxes and crap like a little burlap bag for their ‘widget’. (Not to mention the required stickers or ‘morale patch the ‘can company provides).

      Anything to differentiate themselves from ‘the pack’, I suppose. And *we* are the ones footing the bill…

  12. Bmworld

    This is kind of a week review I feel like you should have not have bothered to post it if you weren’t going to complete the testing

    1. Hannibal

      Yeah I don’t really understand the point here… there’s some pitting so you decide to quit and save money on ammo? What?

      Also, I second the concerns above about ruger threading.

      1. Tex300BLK

        You want him to run it some more? Why? There are cans out there that have been run thousands of rounds with less pitting and erosion than that, so it isnt “just a little bit, as you say. What additional knowledge would we gain beyond being even more convinced at just how badly it sucked?

        First people claimed a $200 silencer is just as good as the more expensive ones, so guntruth found a $200 silencer it isn’t even close and lo and behold it sucks a giant bag of dog dicks. Now you are mad because they didn’t waste their ammo proving beyond a shadow of a doubt just how badly it sucked? Guess you just can’t win some days.

        1. John E>

          I am just trying to wrap my head around the image of a giant bag of dog dicks.

          I mean, why would you have this? What happened to the dogs? What are you doing with it? It’s very disturbing.

        2. LarryinTX

          It’s a toy, John, lighten up! Everybody knows a dog’s favorite thing is another dog’s bidness, sniffing and all, this is a toy to make your dog happy.

  13. Nick

    300 WM through a can made of 7075? I’d be a little dubious of such a claim. Given the pitting from 308, I wouldn’t test it with a magnum. Probably would be safer however if the blast baffle were steel and everything still in aluminum.

    That said, if the others are right about the Ruger rifle having bad threads, you should find a better rifle to test it on and report back after doing a more thorough review.

    1. Geoff PR

      Or at the very least, get the test guns threading verified. It would suck if that baffle strike was a result of an out-of-spec thread job.

      That would be a serious disservice to the can companies reputation if that were the cause…

  14. Bigred2989

    Well, you get what you pay for. Something like this *might* be acceptable in a world without the onerous regulations we have now, but until then wise to stay away.

  15. As a dealer who can confirm their business model and customer service are SERIOUSLY lacking, I agree that a follow-up of this test is warranted with a different (higher end maybe, or threads checked for spec) rifle. I have the SOS-556 as a demo can and have not had any issues with either .223 or .22 (super and sub) thru it. Rebel deserves at least a second chance at this like many other reviews have received. JMHO.
