I realize that “need” is a very subjective term, but I’m thinking of guns that are gassy and hard to suppress due to their design, or a lack of aftermarket options to control gas when running a suppressor. I don’t really think of DI ARs as being hard to suppress because there are so many tuning options available for the platform. I’m thinking more of the 5.56 Tavors that are still gassy because about the only options as a gasketed ejection port cover and sealing up where the rail rear meets the stock, but that doesn’t do anything for the gas coming out the active ejection port.

My list so far is:
Tavor
Original MR556A1 with the fixed vent or non-vented gas block
Beretta ARX-100

Not sure if the SCAR is on the list due to the availability of the KNS DiSCARder or the SCARburator gas knobs. Also, I understand that KNS is coming out with one for the AUG, as there are also suppressor gas plugs out there.

I'd be down for something that has more settings than the factory gas plug.

I found this: https://www.reddit.com/r/AUG/c..._gas_plug_shot_show/

And:



Mine has the factory suppressor gas plug; it works fine using my Dead Air Nomad Ti. I've only noticed gas to my eyeball when tilting the rifle 45 degrees to use an offset red dot. It's enough to make my eye water. Going from 3 settings to dozens would be worth $159.

First I can't imagine why the SCAR would be on the list. There is no system that has as much capability to tune gas as the SCAR. Change the gas jet to match your load and suppressor. Done. Now I get that some people want some kind of mythical gun which can run anything suppressed or not, good ammo and bad, short or long suppressors, and mix them all up etc. Then the SCAR gas jet system is probably not the right fix as while its certainly doable in the field its not clicking a knob.

The Bren 2. Or you can have the factory piston modified (HB Industries does this, I think) for a true suppressed sitting in what normally would be the "off" position. It's possible that CZ sells a solution as well. I had HBI do mine.

I'm not sure what we are trying to list. The number of guns that I can personally say suck at being suppressed is a very big list. Are we discussing a subset of that like 5.56 guns? Or 5.56 guns that take AR mags???

I understood it as guns that have no OEM or aftermarket remedies that serve to mitigate the adverse effects of silencer application.

I'd add the HK G36. I've shot both the C and K configurations. While they run, the recoil impulse is atrocious, and it feels as though wear and tear is a real potential problem. Not to mention the exacerbation of the flash signature from the gas vent. The design just doesn't lend itself to suppression, and the relative unavailability of the platform to the public has resulted in a lack of interest in the aftermarket. I opted to use an OSS HXQD silencer, which made things hunky-dory.

Ok maybe a bit of thread drift. One of the guns I'd like to figure out how to suppress is an AK. I'm not super fussy on caliber as I have them in several. But it seems there is no way to get rid of the excess gas. Anyone have any experience.

The first sentence is what I was talking about. I agree with the G36. Other calibers are fine. Not sure about the Bren 2. The 16” carbine, at least the 5.56 version, has a suppressed position on its gas block, while the shorter barreled pistol versions don’t. Although as noted, HBI can fix that and is a pretty common aftermarket accessory.

I think KNS makes their adjustable pistons for the AK. If not totally married to an AK47, one could opt for a Galil ACE or Swiss 55X. Both are arguably "better" AKs, and may play better with a silencer.
