Ase Utra Dual flow suppressors

[sirhitalot]

Hi guys. I want to suppress two ARs (.223 and .308) with the same suppressor, and since i live in Europe the Ase Utra looks like a nice way to go. My plan was to get the correct caliber muzzle brake for both the 223 and 308, and then use the Ase Utra Dual 7.62 for both. I care most about low back pressure and recoil reduction, as i will be wearing double hearing protection anyways. These are quite reasonable priced compared to the bigboys (hux etc). Ive got loads of baffle suppressors that could be used, but i wish to minimize back pressure and be able to switch between muzzle brake and suppressor without adjusting gas block and minimum POI shift.

There is very little talk about these, has anyone experienced these or have anything to say about the Ase Utra flow suppressors?

You mean does the 7.62 version work correctly on the 5.56? I guess since the hole is a bit on the big side for smaller caliber it does not take as much decibels down as the dedicated 5.56 one would, but otherwise I don't see why not. In general the AU suppressors are quite nice products, do their job and have good lifetime/durability, and we have plenty of those on our rifles. Mostly boltguns though, semi-autos have rather the Brugger&Thomet ones. I've also seen Silent Steel products that are on par with the AU.

I was interested in experiences in general. I know an overbored suppressor will have some loss of efficiency, but thats fine. Im more interested in how they perform with respect to added back pressure compared to for instance hux etc. For instance the ruger sfar only has 4 step adjustable gas block and my buddys baffle suppressor created alot of gas at the most closed setting.

I own dual short in 223 size and have used it in mr223. It does reduce backpressure a lot compared to my legacy style SL5 suppressor.

As mr223 is short piston, my gassing will not probably compare to yours.

My problem with the can is that its weight and size is quite big compared to sound suppression.

I use SL5 which is lighter, smaller and suppresses better, might say exceptionally well but I do not know if regular AR can be tuned for it and what actions would be needed.

On of the practical problems with dual I encountered was that it became clogged with carbon. I think the fact that I have it mounted over the muzzle break and not the flash hider is the reason the pressure does not push the dirt outside but instead it collects inside the first chamber walls. But this clogging eventually showed as more backpressure. This started my cumbersome journey into cleaning CF suppressors..

(Onto a sidetopic for one paragraph) The SL5 collects carbon also inside the first chamber but I can quite easily clean it by soaking it with toilet detergent after first protecting the borelock sleeve with WD40 to prevent it from rusting. I tried ballistol which does nothing, actually no carbon was removed) and schletek (recommended by AU), which corrodes the BL sleeve really easily, smells horrible and is mediocre at removing carbon but atleast does it. The detergent works really well and is also cheap and easily dosed. Try them on your muzzle device and see how they do. And yes I own a good ultrasonic cleaner and still gave up on it after it became clogged again quite soon.

My friend has the Silent Steel suppressor and it is pretty much what I would recommend. It is louder for sure than my SL5 but it suppresses well and he can shoot it without problems, feeding is maybe 2 o'clock and it is on an LMT without any gas options. His LMT also changed completely into much more precise gun and he shoots it a lot more now. It is direct threaded and the can directs gas flow so that it tightens it with each shot! The Silent steels can be also disassemled, a feature which you will beg for down the road. It is also lighter. Keep in mind, you will also use maybe 80 to 100 grams of suppressor cover on top of it to stop it from burning you.

Definitely, clogging is an issue with all low-pressure suppressors. For some more and some less. Muzzle brake does act like a baffle but it affects that much? Otherwise AU suppressors are solid pieces as far as my experience is with SL7 and Jet-Z. Been constant in POI shifts. Backpressure increase? AU itself advertises as +5%, that should not make a lot of difference. When I visited them the story was the same - does not really matter either on or off, as the difference is not large. Longevity? I haven't seen any of their flow-throughs being used to the end of life yet, at least here, but my expectation is to see similar lifetime as B&T or Silent steel. Well, clogging again. The ports are small and maybe it would be reasonable to go with flashhider to help blowing carbon out. Maybe.

I would also recommend the Silent Steel on the basis of cleaning ease and that the core tightens itself with shooting.

I have done what you are discussing, just with a different suppressor. I bought the HUX 7.62 and use the same muzzle device for 5.56 and for the 6 ARC rifle. I have had zero problems switching between platforms and I do not have noticeably different results when I am behind the rifle, they sound about the same.

Thanks for the thorough reply. Interesting that the silent steel is recommended over the Ase Utra. I would expect the steel mesh inside would be a nightmare to clean. Ive got 5 baffle suppressors and never clean any of them. I feel like that after an initial fouling build up it blows itself clean when in use.
