6.5CM suppressor recommendation

[Bubba scrub]

I know the horse is dead, but I'm looking for recommendations on a 6.5CM can.
Priorities are:
Max decibel reduction
Minimal or no "First Round Pop".

Not worried about size, weight or caliber versatility. I'd like to keep it under $1500 if possible but I'll consider higher priced options.
Current considerations are Ultra 9 and Hyperion.

I've seen what PewScience has reviewed but the tests are a few years old now, and I know there have been some updates to the Ultra 9. Unsure about the Hyperion- While the Hyperion won in PewScience testing, some say the Ultra 9 .264 is quieter than the Hyperion in .30... I had been warned about falling down the rabbit hole...but here we are.

Is there a clear cut winner for my desired characteristics?

Don't overlook the Otter Creek Hydrogen L 6.5, CAT JL, PTR Vent. Splitting hairs at some point as the supersonic crack is going to be there regardless...

The two best 6.5 cans on the market are the Airlock ZG 6.5 and the US OG 6.5.

If you want stupidly quiet without worrying about length or weight or looking like a sex toy, the AB Raptor 10 with 5” reflex fills that role.

PS - the TBAC suppressor summit reports are another great resource for comparing many suppressors.

OCL hydrogen 6.5. I have an S and an L, great cans, cool company. Just not many out there.

OP, I have the Hyperion and two Ultra 9 Gen 2 6.5’s. I got my first Ultra 9 after the Hyperion. Then I bought another ultra 9 instead of Hyperion if that says anything.

I have a 6.5 Ultra 9 for both a 6.5 CM and PRC. I love it. I am a TBAC guy though and dont have a lot of experience with others. I also have an Ultra 7 30cal and a takedown 22.

From what I’ve seen, the absolute quietist you can get is PTR Vent 1. PTR doesn’t have the best warranty though. Another candidate that’s very quiet and with minimal FRP is OCL Hydrogen and they have an outstanding warranty. The 6.5 bore L length will be quietist for 6.5, but the S length is a good compromise for shorter length while still being pretty quiet.

What do you mean by best? I’d be surprised if either were the absolute quietist.

Well, I mean best all around combination of features, not absolute quietest. That’s why I suggested the AB Raptor 10 for that characteristic.

I'm sure any of the big cans would do well. Based off 30 cal results, the OCL hydrogen L in a 6.5 bore seems pretty optimal. An ultra 9 6.5 would probably kick ass too. 30 cal Magnus, Nomad LTi XC, etc i'm sure would do well too.

The quesadillious lady meant most popular on Rokslide, having not read the OP's thread.

I see what you mean, Q. Though I doubt the Raptor is the quietest nowadays after recent innovation from CAT, PTR, etc.

I try to only recommend things I have personally used. Where I am not doing that, I try to be clear about it and point the person to the source.

In this case, I don’t know what the AB Raptor 10 objectively measures (it hasn’t been tested at the TBAC Summit). Same for the ZG 6.5 and OG 6.5. But I have used all three one after the other and in hunting situations. The AB Raptor 10 with 5” reflex is “stupidly quiet” (that’s entirely subjective). I’d love to see it tested at the TBAC Summit and objectively compared with some of the other 7-9” cans on the market.

The only sound numbers I fully trust are the TBAC Summit ones, because they have a consistent setup and a baseline measurement of an unsuppressed 20” .308 with which to compare. The normal fluctuation in testing values from day-to-day are such that even a trustworthy company’s numbers have to be taken with a grain of salt.

 

[ckt3]

Makes sense. I favor Pew Science methodology over TBAC, but I’m grateful both are bringing some transparency to the suppressor market. I agree that any company’s own published numbers should be taken with an enormous grain of salt.

I'll second that the AB Raptor 10 w 5" reflex has been ridiculously quiet. Having shot with it at an NRL hunter match, I had comments on how quiet it was from the ROs. Given how large it is, I have a hard time imagining something else being much quieter without being obnoxiously large.

I have a ZG 6.5 on the way, which I'm thinking will be the perfect hunting can. Certainly not the quietest possible, but a good mix of size/weight/suppression.

For max suppression without any concerns for size or weight I’d get a TBAC 338 Ultra G2. I don’t think anything will compare. If your true goal is max suppression and minimal FRP that’s your huckleberry.

It’s the U9 noticeably quieter with less FRP than the Hyperion or do you have different priorities that rank the Ultra above the Hyp?
Thx

OP look at Pew Science rankings, filter to .308 ammunition, sort by quietest suppression rating at shooters ear. If you want to be objective, the Pew Science data source is the gold standard currently for evaluating suppressor sound.

I haven’t shot them back to back on the same host. I can’t tell a difference by ear which is quieter. With ear pro on at the range I like the sound of the U9 better. Hunting it doesn’t matter to me.

I use a 338 Ultra Gen 2 on my 22 Creeds now, which is noticeably different from those.

Seems like great reviews, although, the ~$2300 price point has me cringing a little.
