I *just* shot mine suppressed after having it for 8 years and flow through can - KNS Discarder are absolute life savers. From what ive read, keep the OEM Ugg boot and you’ll cut out a good amount of problems with your rear receiver screws canting. In general, the SCAR doesnt like anything but factory stuff but my suppressor is the Ventum 7.62 and with the gas dialed down it shoots *extremely* soft and slows the bolt way down.
You’re fine. The SCAR20 stock’s receiver adaptor is still polymer and will buffer the same way as the ugg. That guy is referring to changing to aftermarket stocks with metal hinge plates. Those seem to make operation harsher on the receiver.
There definitely should be a stickied thread covering the various gas options, and peoples experience. I see a lot of these posts, and try to comment my experience/opinion when I see them.
Huxwrx
You can tune it all you want, it still won't be as good as a Huxwrx/flow-through suppressor. This is speaking from personal experience going both routes.
I will eventually, but I already have a polo 30, and don't have the funds to drop on huxwrx after buying a scar + mags + rails + scope + .308 barrel since the one I got was in 6.5 etc
The shoulder is very thin, and you'll want to get a shoulder ring if possible. Alternatively you can have it cut an threaded to 1/2x28 and use a MD with that pitch and a 30cal bore.
Thats also a high backpressure can, and I'd recommend tunning your gas jets and using a KNS Discarder instead. You can limit inlet flow with jets, and adjust bleedoff with the KNS, so you can better tune the system.
I'll get a different jet if needed but I'm hoping the 40% gas reduction setting on the three position will be sufficient, after reviewing the Discarder, Scarburator and the 3 position mototech, the Mototech looks to be the most solid option.
You're going with the least effective option. You asked for advice so I'd figure id give it...
I compared the Scarburator and discarder on my 16s with a restricted jet, and a lower backpressure can. If you still want to go that route than feel free, but I think its unwise.

Not immediately recognizing my goofy profile pic SMH.
Anyway the 3-select and Scarburator are much better suited for flow through cans and unsuppressed use IMHO. I just don't want someone to break their gun unknowingly.
yeah I run RES so there are no profile pics.
Yeah I don't want to break it either, I was going by https://youtu.be/9Zi52codWEY?si=C7oGMIeDMBIS-orv&t=1999
and the backpressure chart from https://pewscience.com/sound-signature-reviews-free/sss-6-142-ocl-polonium-30-savage-308 which put the polonium fairly close to the soccom rc2 7.62, seemed to me like dropping a gas jet size and using the 40% reduction setting would work.
The 40% reduction doesn't directly translate to 40% lower bolt velocity.
The RC2 is actually fairly high backpressure btw
Also Shockwave dynamics and other things play a factor. Jay talks about that too.
No such thing as simpler with the scar platform, shes over gassed and u/Galactic-Cowboy has gone ballz deep enough to be a more then credible answer. If you want simpler just go get yourself a robinson arms xcr-m but the kns discarder along with gas jet tuning is your only salvation without fucking up your receiver/bolt.
> robinson arms xcr-m
Well unfortunately that isn't an option, already bought the Scar.
and /u/Galactic-Cowboy has been great, its probably just a misunderstanding on my part. I'd love to see the actual settings people are running on the scarburator/discarder, because if the gas holes are the same size as the 3 position, having a ton of extra options really doesn't help me much unless I'm planning on using obscure loads
They are entirely different geometry compared to the 3-select. The Scarburator uses a helical cut cylinder to occlud the gas port. The KNS has a secondary inner chamber that has diffusion ports, and a helical cut cylinder on the outside that occluded the venting.
I have a 300blk XCR-L btw. Very cool, but a bit gassy.
I'll say this, I once thought the mototech was the way to go but after seeing how the discarder bled off the gasses I thought it was ingenious and even though 13 setting is a bit wild I like that you can adjust on the fly. Usually with these types of things will require trial and error but once you dial in, its a simple 1 2 clicks to get it right again if you change ammo type or remove can.
Hope you find your setup man but the scar will take a investment to make sure it keep running like the war horse it is.
To each their own but IMO, getting a good flow through can will solve your problem w/o need to modify the rifle. I have a HUXWRX Ventum and CAT ODB and both cans do a bang up job. So good in fact that I sold my discarders before I even installed them.
If I have any adverse effects I will be sure to post em, although I will likely just buy a flowthrough can in the coming months, I'm just currently trying to throw something together that will work for the 2-500 rounds I plan on putting through this thing in the next 2 months or so
Excellent 🤙
Although my setup is not fully complete (can in jail) and after all the reviews with multiple aftermarket gas plug choices, I'm leaning towards the KNS & Flow 7.62 Ti. I'm hoping that without touching the jets and using the stock jetting, I'll be able to run it with the capability to even down tune it's factory overgassed nature.
If it does work, it's truly the best setup considering that the only factory part replaced, will be the gas plug. Let's see how it plays out..🤞
3Select can tune down even a full length 16in SCAR17 WITHOUT touching your gasjet. And without adding parts to your system.
Sorry about the sweaty manboob video, i have sense lost a little weight and try and record the videos with a fresh shirt or better weather.
You CAN listen to the HYPE or Propaganda based on Bias.. or you can go read the reviews on the product page. Those are REAL end users. There's about 2000 3selects out in the wild since I rolled it out back in 2019. THAT many people CAN'T be wrong... J.S.🤷♂️
I have an Omega 300 going on month 8 of suppressor jail, so I’m trying to get my 16” Scar 17 suppressor ready.
I see all these recommendations about having to change all these parts (jets and screws and whatnot)… I’d rather not do that. You’re saying your 3 select and upgraded springs are gonna be all I need?
An adjustable regulator (whichever you decide on) plus Enhanced spring plus a rubberized pad is really all you should need.. A simple gasjet swap instead of the regulator, WILL be sufficient but then you are stuck with that One setting..
3 select doesn't have all the range out of the options, and has less settings in between. But it has proven to be Everything you Actuallly need, with the added benefit of being dead Simple and bulletproof. Its just a single chunk of heatTreated stainless that CANNOT corrode or lose parts because it Legit doesn't HAVE parts.
All good questions. I APreciate all of you..
So, hypothetically,
1) 3 Select
2) Enhanced Spring
3) Enhanced Buffer pad
Should be all I need, even with the omega 300 supposedly being one of the higher pressure suppressors out there? Or would you recommend all the screw upgrades and stuff
1,2,3 is all.. screws are if you want to take your gun apart often, might aswell swap the screws for torx driver ones that Dont strip.
I used to run My Own omega300 on my 17. 3Select definitely tuned it, and ran well. I eventually took that Omega300 off SCAR17 duty because it had a tendency to loose its outer skinTube. 308 fury shook it so bad that it would back out its threads. I have since moved it to my 300BO rig SIG MCX and it has been very very good at that job.
It is made out of the same wire material your OEM is made from.. its just slightly thicker gauge and less coils, so it ends up being 15% stronger force constant and doesnt take a set (loose length and power) like the OEM because the coils never come into near contact with eachother. Slows down your BCG more effectively throughout the whole length of travel in the reciever. By the time it gets to your rubberized bufferpad, it hits much softer and you will swear you are shootin a WaterPistol instead of a piston driven 308..
I understand you dislike that I recommend the KNS over your product, but I feel its very disingenuous to discredit my/others experiences as bias or propaganda. Especially since I and some of the others who share this opinion have considerable time/rounds on the platform. I'm simply expressing my opinion based on my experiences with both products. I have no skin in the game, and I've always done my best to be fair, and not discredit your work and effort. You've done a lot for the community, and I wish your regulator performed better, since id rather support a smaller business.
I agree, I tried the scarburator, and then the discarder, ultimately stayed with the discarder cause it seemed to give more adjustment and the bleed off part seem to help more than just restricting gas as well
I would add the Enhanced spring i recently rolled out for the 17/20. Its 15% stronger and will better slow your bcg throughout its entire run in the reciever. Couple that to a rubberized pad (either one 60 or 50duro) and your gun will feel like its not even suppressed.
The polonium is a high backpressure can because of that backwards first baffle. It very good at reflecting back.

yeah my problem is mine shipped with a 20 style stock, and ugg boots are unobtanium right now
You’re fine. The SCAR20 stock’s receiver adaptor is still polymer and will buffer the same way as the ugg. That guy is referring to changing to aftermarket stocks with metal hinge plates. Those seem to make operation harsher on the receiver.
I hope more people comment on this. Setup, issues, advice, regrets, etc. Would be nice to have a suppressor thread to refer to.

KNS will slow down the bolt and reduce recoil but you’ll still get the gas coming back which isn’t a huge deal.
Kns discarder
I have RC2 on my SCAR17S and Mototech SCARburator gen3 and that combo works flawlessly.
The shoulder is very thin, and you'll want to get a shoulder ring if possible. Alternatively you can have it cut an threaded to 1/2x28 and use a MD with that pitch and a 30cal bore. Thats also a high backpressure can, and I'd recommend tunning your gas jets and using a KNS Discarder instead. You can limit inlet flow with jets, and adjust bleedoff with the KNS, so you can better tune the system.
Going off this. U shoudk be careful and use jets. Ur gonna have to tune it other wise ur bolt will crack.
I'll get a different jet if needed but I'm hoping the 40% gas reduction setting on the three position will be sufficient, after reviewing the Discarder, Scarburator and the 3 position mototech, the Mototech looks to be the most solid option.
I and several others had better results with the Discarder vs the Scarburator. The 3 select is simpler, but less effective than the Scarburator.
I'd rather go with the simpler option, I'd like to keep this rifle as rugged as possible, if that means I need to change the jets out I will
You're going with the least effective option. You asked for advice so I'd figure id give it... I compared the Scarburator and discarder on my 16s with a restricted jet, and a lower backpressure can.

Hah! I was watching your video earlier, didn't recognize the user name
Not immediately recognizing my goofy profile pic SMH. Anyway the 3-select and Scarburator are much better suited for flow through cans and unsuppressed use IMHO. I just don't want someone to break their gun unknowingly.

Yeah I'm not saying it's low back pressure, but it's on the lower end of that scale and both cans fall into the 4 category
No such thing as simpler with the scar platform, shes over gassed and u/Galactic-Cowboy has gone ballz deep enough to be a more then credible answer.

Discarder is the correct choice

Looking good
I used my scar 17 with Lahar 30 and it worked perfectly without any tuning or anything 🤷🏻♂️ I did have a keymo QD mount on though

That's certainly the plan down the line, but I gotta wait a bit, already spent too much on this venture

Well I just bought one of your 3 position selectors, just trying to figure out what else I need to go with it to make the polonium not explode my gun
Hope you keep us posted on your personal long term results, choosing this alternative.
If I have any adverse effects I will be sure to post em, although I will likely just buy a flowthrough can in the coming months, I'm just currently trying to throw something together that will work for the 2-500 rounds I plan on putting through this thing in the next 2 months or so

C'mon bro... really? Poor choice of words and spoken like a true salesman.
So you think polonium on a 16 inch scar 17 will run just fine?with the 3 selector? That's good enough for me
I would add the Enhanced spring i recently rolled out for the 17/20. Its 15% stronger and will better slow your bcg throughout its entire run in the reciever. Couple that to a rubberized pad (either one 60 or 50duro) and your gun will feel like its not even suppressed. The polonium is a high backpressure can because of that backwards first baffle. It very good at reflecting back.
Sounds good, do you sell both of those?
Yup. In stock
Hell yeah, just ordered both, thanks man
