 Moore's law should be amended to include suppressors

I bought an Octane 9 last year and I've found it's already been updated with a new baffle stack!



Anyone familiar with the new design? Aside from being able to push the baffle stack out easier if it's filthy, is there any improvement in sound performance?

I have no idea what you're talking about.

762SDN6 - transfer approved Jan 2012, received first week of Feb after SHOT.


SR7 - announced SHOT 2012





I understand they have to evolve and update their designs, but the timing really bugged me.

If it weren't for the NFA paperwork delay time you wouldn't be out of style.

Moore's law would hardly apply to the slow rate of improvement in silencer tech. It's sad to read that those who just bought an SDN-6 are suddenly upset because they don't have an SR7, for example. The SDN-6 that they were excited about when they bought it is still the exact same suppressor and will function exactly the same.

We're really at nearly the limit for suppressing the sound of existing projectiles being fired from a gun. Any advances in the past few years has been incremental, at best.

And SWR will be updating your Octane for free, so don't get too worked up.

If I remember correctly, SWR has stated that the upgrade is lighter and quieter, but don't quote me on that.

I don't know if theyre doing the upgrades yet, but as soon as my form 4 comes back ill be calling SWR to get the details.

SWR Octane9 HD Video

I've been shooting the piss out of my Octane HD, and let me tell you, after 500 rounds (factory recommended cleaning interval for the old design, per the manmual), you'll need a dowel and a hammer to get the baffle stack free. It's kind of a pain in the ass to get the carbon out of the tube; for now I'm relegated to a mineral spirits soak and a soft bristle brush.

Another thing I've found is that when switching from the 3-lug mount to the threaded piston, if you shoot the 3-lug first the booster housing becomes so crudded up with carbon that the threaded piston will not go in without first scraping it out. Tapping the piston into place will shave off the rest of the carbon on the walls of the booster. I learned the hard way, so nowadays I shoot it on the pistol first and them move it to the 3-lug.

The enclosed baffle stack will be a good thing for the sake of cleaning, and hopefully it extends the factory recommended cleaning interval. From the looks of the video from SWR, the cleaning interval might be doubled, which is good. The "upgrade" to Osprey pistons I'm still unclear about, but I'll wait to see what SWR has to tell us. Hopefully I'd still be able to use the 3-lug and current piston with the "upgraded" specs. We'll see....

3-lug will still work. I don't think the same piston is going to work. Switching to the Osprey pistons changes the booster housing and endcap and I don't think the old endcap and booster will be compatible with the new booster stack. The housing and cap are what hold the stack in place, and a new stack will probably require changes in the dimensions of those parts. If you notice, they've ditched the locking ring from the original Octane design. Also, manual from the "new" Octane HD tells you not to remove the booster housing, which the old manual didn't mention. I don't think the parts will be compatible.

My post was more of a bitch on the NFA process than anything.

However, you bet your ass when I buy the latest and greatest that I'm annoyed when something better comes out before it's even in my hands.

I think the second part of your post is pretty much spot on, at least in terms of suppressing AR15s and the like.

If you look at the "right ear" results they are within about a decibel or two of 143db for all the cans they tested.
