Suppressors Mount or direct thread?

[TonyAngel]

I have a fair bit of experience shooting suppressed, but until recently, I've never felt compelled to own a suppressor. I've always thought that shooting suppressed was more of a pain in the butt than it was worth.

I have, however, reached the point where I'm thinking that it doesn't make sense not to invest in a few. In any case, I have a couple of them coming. The big question that I have bouncing around in my head now is the attachment method.

It was my intention to just go direct thread, but the YHM srx system seems pretty cool. In my research, I've run across comments made by reviewers wherein they noted that the choice of mounting system can affect the sound of the report to the extent that it can make the difference between the report being painful to the ear and not.

Have any of you experienced this?

Every time I direct-thread, I wish I'd had a mount. I have all of my rifle suppressors rigged for SiCo's ASR brake system of mounting, and it works great for me. My pistol mounts are usually tri-lug, with only my .22 cans sporting direct threads.

 

[DemonicLemming]

I haven't noticed a different in mount type (or DT vs mount) making any difference in the audible report. Maybe not wearing earpro, there'd be a discernible difference?

The only problem with mounts is a lot are proprietary, and expensive. If you don't need/want Keymo, Plan B seems like the best alternative and a lot of companies make HUB mounts and muzzle devices for it. Keymo is neat but it's heavy, long, and expensive. Area419's suppressor mounts are nice, too.

I have a mix of Keymo, Plan B, and DT, but mainly because it lets me differentiate what cans are used for what; DT for (primarily) hunting where I don't need QD but need lower weight and less length, Keymo for 5.56/6.8 ARs, and Plan B for 300BO/350L cans so they don't accidentally get put on something they're not rated for.

I am fairly new to the suppressor world myself. I wanted to use the first one on multiple rifles so i went with the Rearden system. Put the thread adapter on the can and the appropriate muzzle devices on the rifles. So far I have zero regrets going this route. Same suppression, repeatable POI, and the ease of quick change.

I went with Rearden (plan B) mounts, after using the YHM phantom mounts for a bit.

If you get a phantom adapter and mount that interface well, it’s a great system, but it’s luck of the draw whether or not the mount and adapter snug up perfectly, or between teeth. YHM says that a small amount of rattle (off by 1/2 tooth) doesn’t affect anything, but it does affect my confidence in the system. If I had stopped at 1 can and 1 rifle, the phantom system would have been great, as the first pair interfaced perfectly. After that however, it was always a game of musical chairs to get an adapter to work well with the mount on whatever rifle I was taking out.

The Plan B system is super simple, and the taper in front of the threads keeps them from carbon locking. You can, I have heard, shoot enough to build up enough carbon in front of the taper to lock up the interface, but I haven’t experienced that, yet.

The brake below is a Q Cherry Bomb (plan B system) and you can clearly see how well the taper seals off the threads from the carbon…

YHM SrX user & like the system for us. However, never used any other system AND bought many of our SrX brakes discounted (roughly 30%+ off current pricing). Mostly mini QD brakes & short brakes (low weight, small size). Some flash hiders, just because of availability at discount (at the time). Don't care about braking ability nor flash suppression ability un-suppressed...

At current pricing, I'd probably look further into plan B. Mind, am not that familiar with what's truly available vs perpetually out of stock, so take that into account as well. However more likely to be more future options / companies doing plan B, so more likely lowered future cost & increased availability.

Yeah, the plan B looks to be the way to go, hence my interest in the YHM srx system. They look very similar and, apparently, follow the same logic. Since one of the cans I have coming comes with an srx muzzle device and adapter, I guess I'm going to play around with that before I make an investment in an ecosystem. My intention with the 5.56 suppressor is to out it on a dedicated host, but I know I'm going to want to try it on my other rigs.

 

[DairyDictator]

For bolt guns I find adapters annoying as hell. Every time I pull the suppressor, I clean the muzzle and the adapter so the adapter just ends up being an extra step. Taper mounts are great but I refuse to put a can back on a dirty taper so it doesn't really do anything for me other than add cost and cleaning time.

Gas guns I can understand why some would want active retention, but other than that It's the same problems. You buy mounts and adapters to standardize a mounting system that's already universal (standard muzzle threads). The only arguments I can see are the ability to use the same can for 1/2" and 5/8" muzzle threads without a shitty thread adapter, and active retention with a pinned or rockset muzzle device.

The area 419 hellfire system is really slick. Reverse thread taper mount so no worries with anything coming loose when you remove the suppressor. The barrel adapters are also cheap compared to other systems out there. I have experienced zero POI shift with taking a suppressor off and back on with the hellfire system.

I wish I had seen that about a week ago. And just about every single thread pitch you'd need, too.

KAK seems to be hitting the market hard with a bunch of pocket friendly options. I recently used 4 of their handguards. I can't say they're the best I've ever seen, but they sure are worth $100 and do better than some costing twice as much.

I ran across the direct thread adapter that wolfpack is selling. It's recessed and makes for a shorter overall package, not to mention, probably a bit lighter where weight has the most impact.

Eh, I think I'm probably putting the cart before the horse here. I don't even have a suppressor yet. Still, I'm going to be glad to be able to get rid of the keymo stuff I have. It is chonky.

Can confirm the Wolfpack Armory recessed DT adapter is nice, I run it with an OCL Hydro K on my 6.5x55 hunting rifle. Wasn't that arsed with weight but having a HUB mount that reduced OAL rather than making the can longer is good.

 

[USK308]

I have both direct thread and hub-mount.

My direct threaded suppressors are:
1) Q Porq Chop for my 8.6 Blackout SBR.
2) Rugged Obsidian 9 for my 9mm M17

My hub-mount suppressor is:
Otter Creek Labs - Hydrogen L 7.62 for my 300 Blackout SBR

If I had my druthers, I don't really know if I could pick direct thread or hub mount for all my suppressors. I believe that each rifle has its' use-case and that is the primary component of how I chose each suppressor.

For ease of use, I do like the hub-mount in my Hydrogen L...but install / removal for my direct threads are not really difficult.

Both of my SBRs are backpack guns (Vertx Gammut backpack), so the suppressors are not attached full-time...but I do ONLY shoot them suppressed, so there is a short timeline to install the suppressor. The hub-mount having the lock-ring is a nice feature to have IMO.

 

[oldrifleman]

Mine either mount to an ASR mount on my ARs and Area 419 Hellfire on my bolt guns. Yes, I have two fleets of suppressors (flow and non-flow)

 

[roostercogburn98]

Any HUB style suppressor makes it easy to run whatever you want. I run direct thread on the m70ish, and yhm qd on most everything else

This is what I'm really interested in. As mentioned above, DT on a 5.56 suppressor makes for a universal setup and as small and light as possible.

I have an 11.5 rig that I put together as a dedicated host. The only can I had to test it is a Polonium. As it is setup, it won't run reliably without the can, so the can I have coming is intended to live on its host. I have a YHM Fat Cat coming.

I appreciate all of the input and you've certainly given me some food for thought; but my original question was one of whether anyone notices a difference in sound performance between the use of a DT adapter vs a QD.

I have not noticed any difference, but to be honest I doubt ears could hear it?

Yeah, I'm asking the question because I just heard reference to the issue. The one that stands out in my mind the most is a video I saw. I think it was the guy from silencer syndicate that mentioned it in one of his videos. It wasn't the main topic and sort of a tangential blurb, but he noted that with ONE particular silencer, he noted a pretty big difference in report with no earpro on, between a DT and QD mount, with the DT being noticeably more quiet.

I'm gonna have to try to find it.

 

[oldrifleman]

I am not aware of any sound difference

@TonyAngel...
I had a brain-fart when I was responding. Meant to include that between my 300BLK (hub mount) and my 8.6BLK (direct thread), the sound signature is virtually identical (quiet!!!!). Recently had some fun out in the AZ desert with some buds and when I was shooting either of my SBRs with them about 20 feet away, they could not hear anything except a light pop pop pop.



I haven't put my OCL Hydrogen L on my M4 (same muzzle break on my M4, AR10 and 300BLK), so I can't speak to sound signature with the M4.

 

[trob]

Almost everything I have is 5/8x24, so I just leave the DT module on my suppressors. It’s freakin expensive to swap everything to mounts. I should add, all my DT guns, except one, are bolt guns. And that one AR is a varmint gun.
I prefer mounts for general use AR’s. It’s not real tough to swap the module.

 

[Southpaw357]

If you value your hearing, wear ear protection with all supersonic ammunition. It is not “hearing safe” to raw dog it. Given you should be wearing ear pro, your type of attachment affecting sound is of no real consequence. Only downside to DT is that when you get it hot enough it wants to loosen regardless of how hard you cranked it down.
