Well, I finished it up and tried it out. Tell me what you think, No db meter so just video and some pictures.

A standing O!

Nice video, nice photos, and nice machining.

Justified being proud.

Thanks for show.

Nice work there !!

lets see the inside of the mount.

Nice finish, no bad sound!

What materials were you using?

I too am interested in the inside of the mount.

Did you use a Dater hole in the blast chamber?

I would make the thickness around the bore a little thicker next time, will help you out.

Its 304SS for the whole can.

No dater hole in the blast baffle. Should I put one in?

The mount is just a 3/4 - 10 thread for the M11/9, and then I made an adapter to 1/2 - 28 shown in the pics.

There is a 1.25" blast chamber before the first baffle.

I guess I can't complain for my first F1 suppressor.

And thank you everyone.

1.25" is a bit much for the blast chamber.

Where did you come up with that number?

even if I am shooting 5.56 out of it?

It is what size it ended up after shoving 8 K's in it.

Should I add another K and shorten it?

Thanks

You said it was a 9mm can, didn't know it was used on a 556.

You are on your own in this regard. If 9mm is the registered caliber I would tune it for that caliber. 1 caliber will be better, one will suffer. Which one is more important to you?

Nicely done.....nicely done indeed

I forgot to mention that on the m11, the barrel sticks into the blast chamber 3/4" past the end cap. So there is only 1/2" from the end of the barrel until the first baffle. I had forgotten that until just now, so I cant put another baffle in it.

It is primarily a 9mm can for the m11/9 subgun, but I wanted it to at least do something on other calibers.

Great work well done

Thanks for showing

What machines did you use? Set up?

You demonstrate high quality machining talent.

Again, excellent.

twodollarbill · Post by **twodollarbill** » Mon Oct 01, 2012 11:22 am

Very Nice!!!

I would put a Dater hole in the first K, if it was mine.

He may not need it since his rim is pretty thin, may have compensated enough.

I used a mini-lathe w/ digital readout for all the baffles and end caps. I used a regular lathe (not mine) for the threading of the tube (mini lathe is too short) and a regular end mill (not mine) for the scoop and port.

Great job, sounds great and looks like you were satisfied too. That .22 upper on the mac owned.

cpy911 · Post by **cpy911** » Wed Mar 27, 2013 7:23 pm

Wow, were you shooting .223/5.56 in that? Sounds real quiet.
What did you end up for a blast chamber length?
What is your overall length and length of the individual K-baffles?
What is your bore diameter? I am looking at .410" or .420" for mine.

Yes it was full power 5.56 out of a 11.5" barrel. It is quieter than my Gemtech m4-02, but it is known to not be the quietest. And I built it for the subgun, so I wasn't going for lightweight or shorter length.

The blast chamber ended up being 1.25"

The length is 10.5" and each K is .9" long w/ the blast K being 1"

the bore diam is .400-.410"

You are near Albany? I am just up the road from you in Newberg! Small world!
I am limited to 9.5 inches on the length...that is what I put on my Form1. Bummer.
So, the end of the muzzle to the snout of the first K is 1.25", is that for your 9mm or for your 5.56??? You have an adapter, is that increasing or decreasing your muzzle to snout dimension?
What is your tube OD and wall thickness?

PM sent with another question!

Thanks!
Looks and sounds awesome!

Dude....your suppressor owns!
I was sitting there trying to figure out why the 9mm sounded a little louder than the AR. Duh, you were doing FA on the 9mm and I suppose we were hearing ejection port noise...

Is there a spacer ring that is installed in your suppressor that spaces the endcap from the first K-baffle?
How much does your rig weigh???

Awesome...Can't believe how well it worked on the AR...any signs of erosion of your blast baffle yet?
