Thread: Quietest supressors

So I'm wanting a supressor for my 6.5 grendel. It shoots and kills out to 400m easy enough and id like to make it as quiet as possible. What's everyone's experiences with different supressors? I've used maniatis, hardys, dpt and greystone. But all on different rifles so can't compare.

There was a really good review done a couple of years back in NZ Hunter mag, probably a bit out of date now but covered 20 or more brands/models that were on the market. In general, and from memory, the heavier ones were best in reducing noise.

Shulz and Larsen works quite well, doesnt have the ping associated with some. Has baffles etc that can be added or lessed
Is a bit like a DPT in design (modular)

Hands down MAE stainless from Gary Mcoll at MAE engineering

Then Gabe Ziglianis suppressors from High Country Sport in Fairlie

Suppressor test was in rod and rifle from memory and should be online if you give it a Google. Quietest from memory was a ase Sl7. Generally the bigger the better, volume Infront of the muzzle is more effective than that behind also. Interestingly steel is meant to be quieter than alloy, something to do with the temperature of the gas heating suppressor and how it affects sound?

Obviously big heavy suppressors aren't much use on small portable hunting rifles, I've been happy with both dpt and gunworks over barrels on a 7-08 and 300 mag, the dpt probably marginally better but it's hard to pick. DPT muzzle forward on the 223 I've been slightly disappointed in, although it's probably due to the shorter barrel. I'll probably get an sl5i for it one day as I've seen one in use and was very impressed.

@Larskramer Here you go, settle in with a drink & disappear down the Suppressor Rabbit Hole

Some good info coming out. Highly appreciated. The weight, bulkyness doesn't bother me too much. It's not a bush carry gun, more of a shoot off the quad on the farm at fellow etc.

I have a A-Tec MegaHertz 2 on my new SAUM Barrel.
Hands down quietest suppressor among the ones on my other rifles or mates rifles which are a mixture of DPT / Hardy / and the Guncity ones.
Rifles are .223, 6.5 Grendel, 6.5TCU, 30/06, 300WSM, couple of 6.5 Creedmores, couple 7-08s, 30 Nosler and a 300NM.
They aren't cheap, nor slim and trim but they are quiet and the A-Lock mounting is great

Not a suppressor fan these days but had a stainless MAE on model 7 300saum a few years back, heavy brute of a thing but it really tamed the saum more so than any of the more popular/lightweight suppressors I have had on much milder calibre rifles

I have a hardy on my 7mmsaum, and a greystone 6k on the 6.5saum. I'm trying the greystone from the 6.5 saum on the 6.5 grendel tomorrow, so will see how that goes.

+1 for MAE, insanely quiet

MAE muzzle forward can, heavy though compared to the Alloy models
The Aimsports are pretty good too (think i heard they got new models coming @ sika show, but not sure)

Many manufacturers have brought out new models since that supressor test, i dont think its all that valid anymore.

Yes but you have a hunting mate now who doesnt deserve to be deafened unexpextidly or even expectidly.
I never used one until i got my "best mate" and now i wouldnt not use one.

As far as quietest best to look at db readings provided by teputible makers.

Not much gas in the Grendel I suspect your best results would be from a hardy or mae.

Tough question and no real good answer as too many variables and models.

That R & R test is good but dated now. Some have issues around equipment used but it was the best available at the time.
Personally I use a Hardy, have a 6mm Stealth (Long one) which gets used on a 243 & 223, it is amazing, really good.
and I have Hardy gen 5 and gen 6 compact's on some lever guns in 243 & 358 so hard to compare. The gen 5 243 one is better than what my mates use on their 7m08 & 223 but neither is DPT or Gunworks etc.
Went Hardy Compact at the time due to the short front overhang.
