300 Blackout Suppressors, direct thread or QD mounts?

I'm in the process of piecing my blackout upper together...I will be suppressing it, and I'm wondering about mounting options for cans. The M-Lok rail I'm considering is 9.5 inches and I plan running a flashcan of some sort, but I'm wondering if I should go with something like a YHM QD mount with a screw on can (pricey but what's money), or finding a direct thread unit that will fit under a 1.5 inch diameter slim rail.

Any advice or input is appreciated.

Excuse me, 1.325 diameter.

Main thought is that it might end up costing more with the QD mount and other nonsense than spending a little more on a slim enough can.

Our trust owns QD and threaded. I prefer the thread. The first things we learned in both cases is you must:
Let the can cool before casings the gun, sleeve the can or remove it. It is damaging hot after firing. You need welders gloves/mits (or something similar) to remove a hot can.
I assembled a sleeve from PVC with caps for mine. My son leaves his on and allows it to cool. The more important thing is that the mount is square and properly fit/installed. Baffle strikes do happen. Adapters and barrels are not necessarily perfect, we also learned this.

Are you going to use this in only one gun or multiple? If only one then direct thread but if multiple then qd is a nicer option.

One for now. Hence my overthinking it... I'll likely want to suppress more guns over time, I've convinced/annoyed my wife into agreeing that an NFA trust is useful, and that with my recent step up in employment I should build myself a 300 blackout and suppress it... I'd love to suppress my 5.56x45 rigs one day as well...but for now just the one.

Oh, I've seen dudes melt bags with spare 249/M240 barrels. Fully understand that things get hot.

For my AR SBR I went with a YHM QD. I don't always shoot/transport it with a can on. On my .22LR can I have a direct thread on, mostly because I didn't have a choice, but I like the fact that its basically the same diameter as the barrels as the two firearms it goes between. My next AR can will be a QD as well. I just like the ability to remove the can and have the barrel still outfitted with a muzzle break or flashhider.

I have a YHM Phantom thread on and in hindsight I might have preferred a QD mount.

A locking mount is a good choice on a rifle that might get shot a lot and heated up.

On a bolt gun that might see 8-10 rounds go downrange in a couple minutes it isnt a big concern.

I have a Phantom with QD that I used on two hosts for years. An AR and an FN fiveseven. Their QD mounts are solid, reliable, and easy to use. It worked great except for when I needed them both suppressed and ready to go at the same time.

I’ve evolved to preferring dedicated direct thread on all my stuff now just for convenience. It all depends on your goals whether DT or QD is best.

On my SBR I'm using an Omega 300 from Silencerco and have it mounted to the rifle with their ASR mount. The can is multicaliber so if I ever do a 300BLK SBR I'll be able to use the same can and just change the end cap. Right now the end cap is for 5.56.

I never run the gun without the can but I do like the fact that I can quickly remove it if needed.

Awesome setup. After doing some thinking, I'm going to likely go with a YHM mount and pick up their Resonator. I'd love to go higher speed but from reviews it seems it's a good balance between budget and quality. Probably just run a short rail system so I don't have to worry over it fitting underneath and run a thread on YHM blast Deflector when running without the can.

Thanks much. Pretty excited since the build is getting off the ground faster than I anticipated.

Definitely measure everything. This is my 300blk and my sandman-k didn’t fit. I just cut the rail.

What I was thinking.

Nice setup. Mine will be used for hunting, home defense, chupacabra extermination (I tell my wife they're shifting North on account of the global warming).

Quick update. After way too much research, I've been thinking about going with the Aero Quantum 12" rail, a 30 cal flashcan, and a radical firearms direct thread.

After reading the RF isn't as light or sexy as a YHM or dead air unit, it's heavier, and not as nice but all the reviews suggest that it's a quality entry level suppressor that won't break the bank. The Aero Quantum will allow me to thread the can underneath and give me extra real estate, and I'm thinking a KVP linear comp but I might have to change my choice of rails as I feel the comp will barely clear the rail and I would like to be able to easily remove/install either the suppressor or comp without having to remove the rail.

Any good 10" units that will allow a 1.5 inch diameter can underneath?

Nevermind, found a sweet deal on a Samson evolution 10" kit. Now to just buy the rest of the build piece by piece.


And so the wait begins.

Bit off of my original topic, but here's the finalized build.

8.5 inch KAK industries mekonited barrel
Samson Evolution 10 rail
Cobratac 30 cal Krinkov device
BRO adjustable gas block
NBS Slick side upper
Strike industries dust cover
Aimsurplus MPI tested BCG
Armaspec ambi charging handle
Mil Spec Lower
Magpul trigger guard
ALG two stage trigger
Armaspec 45 degree selector
Strike industries Viper PDW Brace
Undetermined brand amb bolt catch
Undetermined ambi mag release
PAA 1-6 ACSS Gen 3
Aero lightweight 30mm mount
Undetermined offset irons

And after Christmas I'll be putting in for the stamp on my can. I know there's the Honey badger and the boys from 9 hole review made the Dirt Squirrel...guess this is something like a Sh!t Weasel or Trash Panda build.

My present to me for moving up in the world.
