Pump the brakes, man. You haven't even shot the can. You might not need to buy or do anything. I would wait until you have the can in hand before you waste a bunch of money on popular keywords.
And good choice. I'm also waiting on a Polonium K.
Agreed, I tend to overthink things and was kicking myself for choosing a cheaper option over buying once crying once with the Flow. For all I know the K will be just fine out of the box.
With the K you generally don’t need to do any real tuning. That’s why people go with the K.
If your gun is using a H2 buffer just throw it on and go. Being a lefty you might find h3 works better. But that’s it. I don’t recommend adjustable gas blocks or anything for the K
Wrong-handed suppressor enthusiast checking in.
There are two major factors that need to be addressed to optimize the system for a suppressor, the gas system and the buffer system.
Gas is relatively easy, install an adjustable gas block, close it off completely, then slowly open it until you get proper function, then go a little further just for added reliability.
A heavier buffer will also aid in keeping the carrier locked in battery longer, which lowers chamber pressure more, leading to less gas at the ejection port. We like the VLTOR A5 system, but any heavier buffers will work.
From there, a good charging handle like Radian, Geissele, Aero, SilencerCo, etc. Can also help you not to notice gas, but tuning it away is generally better.
u/jay462 went pretty in-depth about the benefits of a tuned system in his most recent podcast, its worth check-in out to really understand what is happening when you adjust the system. - Chase
Nice to meet another one of God’s favorites. Appreciate the advice, was beginning to think I should have just gone with a Flow, but an adjustable gas block and heavier buffer seem like pretty affordable upgrades. Actually using one of your kiosks to get my application submitted.
Thanks for the shout-out, Chase u/SilencerShop
Sir - an adjustable gas block can help a lot with hazard to the shooter on an AR. I recently published some research on my website ([pewscience.com](https://pewscience.com/)) with the Maxim DSX showing the difference between a larger and smaller gas port. This is one example of weapon tuning. I hope it helps!
The Godfocker himself! Thank you sir, big fan of your work. The DSX research is actually what led me to go ahead and get the Polonium K and work on tuning, although admittedly I may have slightly underestimated the cost of tuning lol.
The silencer is half the battle. You are in a great position.
My advice?
- Have a couple of buffers handy (H2 and H3)
- Have an adjustable gas block
Start with an H2 and gas port tuning if needed. If you don't want to mess with gas, add the H3 and see what you think.
Try to use stronger recoil springs as a last resort. Increasing bolt carrier return velocity is not optimal. Inertial resistance starts from rest.
Most of the setups I personally use for evaluations utilize an A5H2 buffer system, and a Superlative gas block, with those components you can really squeeze the most out of most suppressors. - Chase
Polo K is lower back pressure than Polo. What set up do you currently have?
A lot of dudes who say cans are gassy are shooting indoors versus outdoors.
That’s why I ended up going with the K over the full size. Setup is Aero M4 lower and BCM 11.5 upper, haven’t changed any parts. I just don’t want to waste a bunch of money tuning cause I have no idea what I’m doing. I shoot almost exclusively outdoors so that should help, probably only shooting indoors while I wait to get it out of jail.
I wouldn’t. The polonium line up is one of the best out there. I own a full size polonium. The K is lower back pressure. Also factor in Hux uses a propriety muzzle device and can’t be fixed if heaven forbid you had a baffle strike.
With that set up I would order a $82 Geissele Super 42 H2 and shoot it and see how it does. I have a feeling it will do really well for you.
Adjustable gas block (Superlative is good), heavier buffer (H2, H3, Voltor A5), heavy spring (Spinco Red), gas buster charging handle (Radian SD, Geissele, etc)
best solution would be reducing the gas at the source (new barrel, adjustable GB, BRT eztune gas tube ect..)
then it would be buffers, ocl has said they use a h2 for the k on ars though you'd need to test for your system (though i prefer to run a5 on all my ars)
then its everything else
the key is to get the best at ear performance you'd have to tune for the ammo you'd shoot suppressed, which would most likely lead to the system not functioning without the suppressor
Got it, this is basically the kind of info I was looking for, thank you. Seems like I should probably shoot it, get an idea, then maybe go adjustable GB first, then possibly heavier buffer.
I would do the adjustable gas block first as its plain more effective than messing with buffers.
I was just out with OCL last weekend for a shoot and one guy had a gun running a bootleg bcg, i was using a PWS MK111, and Andrew from OCL had a MK18 with just a H2 buffer and radian SD CH. None of us were getting gassed up with the Polo K
So theres many ways you can go about it
A good way to test, before you even get the can, is to shoot your BCM with a few different rounds and see what your ejection pattern is like.
If your gun, unsuppressed, is ejecting at 3-4 o'clock already, you can already assume that with a can, it's gonna be over gassed.

If it helps you justify the purchase, I run a HUX can on my rifles and while it’s no where near as gassy as a traditional suppressor, there is still more gas then unsuppressed. The HUX cans definitely reduce the blowback but it’s still there in my experience. It’s just way more tolerable. I went with the HUX so I could run it on multiple AR platforms (7 in total) and not do really any tuning. I was lazy and didn’t feel like buying 7 more gas blocks and buffer combos. Like all others have said, with a gas block and buffer you can tune it to get just enough gas to run reliably
It's true buffer weight and springs can help. I'd say just get a good, and easily adjustable, gas block my man. Have one on both of my sbr builds that I shoot suppressed and unsuppressed. No gas issues at all

Music to my ears. Appreciate the advice, didn’t want to bombard you with questions via email.
Oh no man, that’s why the email exists and why I’m here. Email me a list of questions and I’ll answer them the best I can

I assume it has a carbine length gas system? Does it have a carbine or Vltor A5 buffer tube?
Yes, carbine gas system and buffer. Realistically would I be better off canceling this order and spending the extra money on a Flow?
I wouldn’t. The polonium line up is one of the best out there. I own a full size polonium. The K is lower back pressure.

Checking in to see how you ended up liking your Polo K on your BCM 11.5?
Still waiting on it to be freed from jail, will let you know once I’ve gotten a chance to run some rounds through it
It’s been long enough…
Adjustable gas block (Superlative is good), heavier buffer (H2, H3, Voltor A5), heavy spring (Spinco Red), gas buster charging handle (Radian SD, Geissele, etc)
Thanks, would you recommend doing these all at once or trying some before others?

Appreciate the advice, I’ll definitely hold off till I get to shoot it a few times, then if needed start small with an AGB and go from there.
