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.

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.
