300 whisper suppressor

[SwampF0X]

What would be the best suppressor for the 300 whisper? I've read that some people are using a 9mm can. Is it just as quiet as a 30 cal can? I will be shooting subs through it almost exclusively.

I would like to keep my barrel length at 16" and have a partial integral suppressor to keep the OAL as short as possible without getting the SBR stamp.

Just looking for recommendations.

thanks,

I've read that the 9mm suppressors work quite well on subsonic 300 Whisper. I've also read that you can't shoot supersonics through them as the pressure is too high. I have no personal experience trying a 9mm suppressor on a Whisper though, I use a YHM .308 suppressor.

If you keep it sub, pressure won't bother it. Liberty is one company that will make you a reflex style to keep the length down. DeGroat Ar. makes a 12" that is excellent. It will add a lot of length. Ops Inc makes a reflex type that is rated up to the 300 UM.

It depends on what you want or need to do with it. I mainly hunt or plink, but the 762 is accurate on my bolt gun at long ranges. I have a YHM 762 and a YHM 9mm XL for carbines. I use the 762 on my AR 762x39, 16" barrel. It is heavy out at 16", but I can shoot super-sonic or sub-sonic. Mainly use it super-sonic now because I built a 300 Fireball 10 1/2" barrel threaded 1/2-28 so I can use the YHM 9mm XL. and sub-sonic only. It is very light to tote around it the woods. It does not spook the animals bad and I can get 3 or 4 kills out of a group of hogs, but, a couple of weeks ago using my AR 762x39 super-sonic, I got 2 hogs and 8 pigs. So it depends what you are using it for. I am lucky that I have both.

I'll be using it for deer hunting primarily. I would like to be able to use it with super-sonic rounds even though I won't be shooting much of those if any. I guess I want my cake and eat it to LOL

Call the Major. He will give a no BS answer without bias. He is a dealer for everything so he has no stake in what brand you buy. His prices are bad ass too.

If I go ahead SBR it, how short can the barrel be, without interfering with the gas system and leaving enough barrel in front of the gas system to thread it for a suppressor? I think I'm gonna go with a 9mm pistol can. Lighter, smaller and If I want to shoot supersonic rounds I have plenty of other rifles for that.

PS thanks for the link.

It would be good if you cold hear them shoot. The 762 can is going to be quieter than a 9mm pistol can and a little quieter than a 9mm carbine can. There are silencer shoots around that you could go to. I don't mind demo mine because I like to shoot anyway if you are anywhere near me.

What is a reflex style suppressor? I've never heard that term.

As for barrel length, mine is a 10.5" and it cycles well and is a handy length with my YHM 7.62 suppressor attached. I think you can go shorter but my suppressor, according to YHM, should only be used on 10" and longer barrels for what that's worth.

It's where the barrel goes farther up the can


Idea is to not extend beyond the existing barrel much by having the
primary expansion chamber behind the muzzle surrounding the barrel.
