Osprey 9mm Suppressor on 300 Blackout

fabsroman said:

Not correct. The threading on the barrels just have to be the same, or you just need to buy an adapter. I plan on using the same suppressor for .223, 5.56, and .300blk.

1/2x28
5/8x24

There are others, but those are the most common for rifles.

Well I get that. I just meant the supersonic blackout rounds are enjoyable. More recoil and, IMO, more explosive impact. Fun for shooting steel or interesting (READ: one shot) targets. I haven't shot subsonic but I'm not particularly interested due to pistol-like muzzle energy. Either way, I don't doubt you'll have a blast.

Thanks for the info. I did purchase a spacer for the Osprey for fixed barrels, now I just need to get a thread adapter since you can't get a piston with 5/8 X 24 threads.

Be careful with thread adaptors. They are not often concentric and tend to unscrew when you dont want them to. Check them thoroughly when installing them, preferrably with a suppressor alignment gauge (geissele makes a 5.56 and 7.62 model). I wont use thread adaptors because of the problems I have seem with them, but your reasoning is sound for your proposed application. Just proceed with caution.

Thanks...I will certainly heed your advice - will also look into getting the alignment gauge.

You need to shim the mount to each gun. I believe it is best just dedicated to one pistol.

What do you mean you need to shim the mount to each gun? I use mine on multiple pistols, all you do is unlock the cam arm, rotate it to proper orientation, and then lock it back down. Incredibly easy, no shims required.

I was mistaken about that. I looked it up after the fact. My bad

For the OP. You do not need to use thread adapters for your rifle can. You can use a suppressor mount/flash hider instead.

Those adapters/mounts are for SDTA's solvent traps. They will not work with an Osprey.

Earlier she asked about making a suppressor in 5.56 or .30cal and how they could be switched between rifles with different threads.

beretta_maven said:

You are absolutely correct...and I've decided to go ahead and build the .30 cal can to use with both calibers. Thank you for the inputs!

Better to build the suppressor for supersonic and never want to fire supersonic through it, than to build it smaller for subsonic and then want to shoot supersonic through it.

Other than the noise, I have no idea why people would want to shoot subsonic versus supersonic. Does breaking the sound barrier have something to do with accuracy? More speed means more energy on target. More energy on target means better knock down power and a greater chance of putting game down or a person completely out of a fight.

I guess I can see the utility in reduced noise when shooting/hunting in urban areas where the noise would possibly piss of the neighbors.
