I’ve found a wealth of information on pros/cons of various 5.56 cans. I was originally leaning towards the OCL Polonium K but I’ve been thinking lately that one of the flow through style cans like a Huxwrx flow 556 may be a better option.

What are you all running and what is your recommendation if you’ve run various suppressors?
 
Been enjoying an otter creek polonium for the price, with hub mounting and its plenty sturdy for anything im doing with it.

Adjustable gas on the 14.5 and 12.5 5.56 and it runs great. Same on a 16 inch bolt 5.56. Likely be gassy on a typical rowdy gas system though. It also takes the bark out of the 6mm creedmoor well since its got a 6mm bore.

Poi has been repeatable with direct thread hub mount and pretty much all vertical shift on multiple platforms.

Its a bit heavy compared to the lighter stuff, but no other complaints for what it is.

Thanks for the insights the polonium!
 
Been using a B&T SRBS 7.62 and HuxWrx Flow Range 36 on my ARs and they work great. No need to adjust gas from non suppressed setting. Used on .223, 6ARC, .308 and 9mmPCC for the 36.

Anyone using the Lazarus 6?

Just got a Lazarus 6 and going to do some more testing with it tomorrow morning but it’s a nice small package. It has some weight to it for its size but I doubt anyone could kill it.

for sure a durable can. I have been using it mainly on an LMT 5.56 12.5" cut down from a 16" so the gas seems to be perfect and very little gas/blowback. As Rob01 mentioned it's a heavy little tank but if you want a short durable can that can handle 6mm as well (my plan had been to get a 6mm variation at some point (ARC/Max)) it's a solid choice. Very happy with mine and would buy another (and may do that). One bonus is not having to worry about it if I play with a super safety and dump a mag or two.

I'm a flow-through truther at this point. Being able to just plug and play without any extra tuning while also not getting gassed out is just too good to give up.

Flow 556k or Lazarus 6 would be the two front-runners for me. I have a previous gen OSS HXQD 556 and its the nicest of my cans for longer range sessions. I'm personally looking at 6.5 creed suppressors for an AR-10 and the flow 762 and sandman x are at the top of the list currently.
 
I looked around quite a bit when looking for my first suppressor. I'm one of those guys that wanted most from a suppressor, if I couldn't have it all. Where I chose to sacrifice is in the back pressure department, while getting small and quiet.

I tried several suppressors, including the Poloniums. I landed on a YHM Fat Cat. Its cheap, so the fact that it is a consumable doesn't sting so badly. It is very short. With its included mounting system, it adds little more than 4" to overall length. It does very well at suppressing sound and flash as well.

I'm not saying its the best, but the price to performance ratio can't be beaten.

This was interesting as well
 
Yeah, that exigent defense suppressor sparked my interest as well, due to its sound performance. If that sort of thing interests you, maybe check out the Cobalt kinetics scrambler as well. Its pricey, but very nice. What I found to be pretty cool with the scrambler is that they have a direct thread model where they take advance of no muzzle device being used and add an additional baffle. The one I shot was mated to a cherry bomb and it sounded nice.

On the other hand, I didnt feel compelled to steer away from the far cat either. I bought a second fat cat.

This was a pretty decent video showcasing a ton of different suppressors. TLDW: the standouts I had never heard of were two cans from ridgeback defense, which I had never heard of. Their 6" titanium can was quieter than full size cans and seemed to have the lowest muzzle signature, despite being titanium and 9.5oz.

Unfortunately they didn't feature any of the cans I am personally most interested in: The YHM fatcat, the B&T XH, and (if price is no object) the Cat KK.
 
On a side note , I think going with a hub suppressor is the way to go just in case the op wants to try out a few different supressor mounting host over time . The first suppressor I bought was the da nomad hub and I originally used the keymo mounting system . I have now switched to xeno and I am glad I went with a hub supressor vs a supressor with a dedicated muzzle attachment.
 
I have a few cans polo k, omega 36, Lahar 30, and a few others and honestly my polo k sounds just as good as my full size cans! It may not be flow through but it sounds great! For 9mm I like my rad 9, and obsidian!

There are so many new cans on the market. They are releasing new cans every week. Been looking for a compact can too, just so hard to decide.

For a True low runout, CNC welded hard use 17-4 can in 5.56 go Abel Biscuit .

I have about 2.5k 75bths since getting one a year and a half ago and the more i shoot it the more i like it.

Gun was a tack driver before i slapped the Biscuit on and is still a tack driver.

400rds this weekend at a gasser one day like nothing.

I like my Polonium K 5.56, adjustable gas block on all 3 rifles I use it on, all 3 run happily with it, consistent zero. I use HUB mount with Rearden single port brake muzzle device on all 3 hosts. Two 16" and an 18".

I haven't used suppressors before this, and haven't used any flow-improved ones, but I don't find the Polonium K to be ultra-gassy. But also, I haven't used it for heavy round count drills or classes, maybe it seems gassy in those settings.

Polonium/K are great cans, especially with AGB or on a bolt gun. If you ever shoot one on an untuned gas gun, though, you’ll find it gassy.
 
For my 556 uppers--and a having them in my left hand--I have found the OSS/ HUX to be the least gassy. (some but not all of that experimentation was done with a AR10 and with 300 blk). The OSS version are good and the FLOW versions are quite good.

A few weeks ago I did a back to back comparison with my FLOW 762 and new PTR Spirittus I (with HUX adaptor). On the 11.5" upper--to my ears--the FLOW sounded less... boomy. I was surprised, given the good reviews the PTR has and I want to do it again to confirm...

Using the gun and ear pro, I can't tell too much difference btw the FLOW 762 ti and FLOW 556 ti. The latter is a bit more quiet but not enough so if you had a hankering for a 30 cal can.

I used a HUXWRX Flow 762 on my 14.5” and it sounded amazing with no need for adjustment from unsuppressed. I then added a Velos LBP 762 with the 556 inverted flash cap and now use that on my 556 and 300 blackout. This can also requires zero gas adjustment. The Velos is a bit shorter, much heavier, and with the 556 end cap it SEEMS a little quieter on 556 although I’m wearing electronic ear pro so who knows. I added the Velos specifically because of its heavy duty construction. The 556 and 300BLK are much more heavy use than my 6.5 Grendel’s and SCAR 17 that use the Flow 762. I will go against the grain saying that the Charlie ASR system on the Velos is BY FAR my favorite mounting system.
Another significant reason for grabbing the Velos 762 was hoping it would suppress 300 blackout subs better than the HUXWRX. My hopes were exceeded. I actually laughed after the first 3 subs.
I grabbed a second Velos 762 with 556 end cap for my girls 14.5” Grendel and 11.5” 556.

1) Suppressors arguably make every gun worse in some way, every single time (they are a trade off). 2) When you are shooting rifles, they do nothing about the supersonic crack and you should probably still wear hearing pro. 3) Purpose determines choice in my opinion, such as high rate of fire and flash suppression or low rate of fire and light weight. 4) Mounting options, direct thread versus some kind of host muzzle device.

Every single suppressor written above in the previous posts are all fine, all of them. If it is going on a gas gun, I personally prefer flow through designs and heavy duty in terms of durability. I personally have had very good experience with Surefire, Knights, and Hux. I will freely admit that there are probably five other good choices for every manufacturer I listed.

Lots of opinions are gonna fly around about a lot of different cans. I'd suggest literally making a list of what you want in a suppressor, in order of importance and then doing a pro/con list list on the suppressors you're interested in.

When someone says that they really like the supressor they got, I'd really like to know why. Is it flash signature, sound signature, weight, ease of cleaning, etc.

I don't know of any suppressor that does it all equally well. Actually liking one suppressor over another is very subjective.

One thing that I want to note about suppressor sound reduction is that it isn't always just about decibel level. What I've found to be more important is the tone of the sound signature. I think that most find lower tones to be more pleasing to the ear.

As I mentioned above, I really like my Fat Cat for its sound reduction, flash reduction and size. If you're considering something like a Polonium, at least try to check out the Fat Cat. The difference between the two for me was the tone. The Fat Cat had a more pleasing tone, to me.

As for all of the flow through cans, is anyone aware of any sort of comparison between any 2, after a lot of rounds? Is there a decrease in effectiveness as the round count rises?

I'd like to see something like a "life with an XYZ can" video that examines long term performance. My experience with cleaning the baffle stack cans that I have, after several thousand rounds, leads me to wonder if there could be a long term problem with flow through cans, due to the small duct work within those cans. Do they get clogged? If so, how hard is it to get them unclogged?

Will a $1500 flow through can that was great out of the box perform the same after 5k rounds?

I think these are good points/ questions.

Even as everyone's ears are different, the why a person likes their suppressor is important. For me and my ARs, not having stuff belch out the ejection port is the most important thing; so for me, its (very) low back pressure cans. Short of a windy day with a tail wind, It doesn't take many quick shots to be in a cloud of gas.

HUX-then-OSS was the first/ one of the first to do it well and I jumped into their muzzle devises. Call it "informed Kool-Aid drinking." From my experience and web-watching, they still do the low back pressure *very* well. But it is true, I had to take the cons with the pros.

Their HUB adaptor has allowed me to branch out and try other options.

As to the lifespan of a flow through/printed can... maybe it's like shooting a 2011. It has more quirks and just takes a little more TLC, and if one isn't inclined toward that, stick with convention baffle cans and deal with their cons.

Of the high flow cans, most recommend cleaning well before the 5k round count (which I assume you randomly picked for the point of that question of longevity. ) But there are so many soak-only cleaning options now that cleaning seems an easier and safer process than it used to be. It may have been on Reddit a few years back when the FLOWs just came out and I kept seeing a HUX rep constantly reply that their cans didn't have a life span of 10,000 rounds when cleaned properly; everyone was posting their disappointment that these fans new expensive cans had such a short life.

A few weeks ago, before a ~1000 round weekend, I preemptively soaked the FLOW 762 Ti for 9 hours (It was likely well short of HUX's recommended ~2500 rounds. Gunk came out. Gunk shot out the first dozen rounds and then it was fine and with no noticeable sparking during one of the night shoots with IR.

If I'm recalling the manual correctly, PTR's instructions say to soak the muzzle end every 500 rounds or so to keep the printed porous "sponge" stuff clear in addition to a full cleaning at the next interval. I wonder how missing that low-count cleaning might mess with the suppression.

I agree a controlled experiment with 2 identical flow thru suppressors would be awesome. But not awesome enough to volunteer. :LOL:

Sunday afternoon ramblings...
 
My instinct would be the sinter-printed cores would need more frequent cleaning. That would be a maintenance negative for that design. The longer you let things accumulate mechanically the tougher to remove w/o some assistance in the removal, like mild abrasive or mechanical scrubbing. Those little pores might be awesome at muffling the blast while letting it flow through the can, but the little pores will accumulate more "complexly" I would think. Lots of 3D surfaces to gunk up and thus later remove.

A stack of metal washer-style baffles offers bigger "flat" areas but far less complexity in what builds up.

I'm guessing the high use mil folks using these have their own cycles on maintenance? I would want to if it were my work use item.
 
I had a friend who used the FLOW for work and he said the cycle was "use for 10k and then get a new can..."

I don't know if he was serious or kidding, but it did make me laugh
Probably legit. Assuming an SBR, that’s likely around the life of the barrel and the bolt. Depends on the firing schedule but probably 1-4yrs of use and then replace. Not outrageous.
 


This was a pretty decent video showcasing a ton of different suppressors. TLDW: the standouts I had never heard of were two cans from ridgeback defense, which I had never heard of. Their 6" titanium can was quieter than full size cans and seemed to have the lowest muzzle signature, despite being titanium and 9.5oz.

Unfortunately they didn't feature any of the cans I am personally most interested in: The YHM fatcat, the B&T XH, and (if price is no object) the Cat KK.


I saw this as well and decided to give the Rhino S a try. Demand for them must have gone up a bit too because I noticed they raised the price a little bit since I bought mine.
