Question for suppressor gurus

I just received a silencerco 9k that I plan to use on a .300 BO pistol. I was planning to direct thread it but the guy at the shop was telling me that it would work better and be quieter using a quick detach mount. Is that the case or was the guy just trying to up-sell me?

I can’t tell a difference, other than it’s easier to get on and off.

How much money do these silencers cost?

Attachment method has absolutely zero effect on suppression unless it's a muzzle brake mounted suppressor. He's trying to sell you a mount that you don't need.

Pffft.............

I can’t speak to that model but there are some suppressors which benefit from muzzle-brake style mounts IF you use them with rifle rounds. Something about baffle erosion. But those are primarily pistol cans.

Won't be quieter, just easier to get on and off. Also QD mounts help make sure that you torque it down to the same spot every time so as not to change POI, not that it would make a huge difference on a 300 blk though.

If you’re gonna leave it mounted and not swap it on/off much, there’s no benefit I know of. If you are swapping it around/re-installing it, there’s a level of consistency for POI shift that is potentially pretty big with some models and barrel combos. It’s why the Knight military suppressor flash hider mounts were specs to all be within .0001 % in weight.....because dudes were potentially swapping M4A1s and other rigs with them, and POI shift needed to be predictable.

That is what I thought. He was just trying to up-sell me. This particular suppressor will stay mounted on this weapon and will not be swapped out. I have another suppressor with QD mount for switching back and forth on other rifles. Thanks for the feed back!

id rather have a mount for it so it can interchange to rifles with different thread patterns by only buying a new mount rather than another supressor

Like most anything in life there are different price points and applications.
$300-3,000

I direct thread mine but I could see a possible benefit in sound reduction with the QD mount which acts like a muzzle brake WITHOUT the can. It would disturb the airflow a little better in the expansion chamber. Is it enough difference to “hear”? That I am unsure of.

I should be getting my suppressor back next month. Is there a good tutorial on mounting it y'all would recommend? I am going to direct thread mine.

Are you serious? You screw it on the barrel. That’s it.

I find it hard to believe someone invested that kind of money in a suppressor and cant figure out which way to turn it to screw it on

Um..... Righty tighty, lefty loosey.... That outta do it.

Getting it back? You mean you had it, now don't have it but expect it again soon?

FYI that 9k is only rated for subsonic ammo for .300blk.....

Look out!! She's gonna blow!!!

would suck to get an over pressured round like i did last i was at range! Pow pow pow BOOM! Blew the firing cap out the back of the casing.

Well it is direct threaded to 300 blackout shoot
Tin nothing but harnady 190 brain blackout rounds through if

The Omega 9k is rated for Supersonic also....

Hmm I thought I read Wednesday that it was subs only...I'll have to recheck the one I'm waiting to lose in a boating accident.

It is surprisingly loud. I shot it next to someone shooting supers out of his and mine with the suppressor and subs was as loud, maybe even louder. Was wondering if this is due it being on a AR pistol?

ARs are always louder to the ear than bolt guns because of the action slamming forward(assuming your subs will cycle the weapon).

You may have been looking at the Osprey 9, they are rated for subsonic only in 300BO. I bought one years ago when the osprey was the only model they offered (serial # is under 100)... its an amazing can, but wish it was stronger and more versatile like their newer models.

My AR pistol with subs is comparable to a 22 Magnum

That is what I was thinking. Something is not working correctly if it is a loud as an unsuppressed gun.

I put the asr brake mount on my rifles so I can swap my suppressor from one rig to the next easily.
