I'm working on a project and I might be looking for a .300blk suppressor with as slim of a diameter as possible, and preferably still fairly short. What options are there?
Thank you

For supers? I don’t know of one. Subs? A bunch of the pistol cans. Rugged Obsidian comes to mind.

Ecco machine makes some slim cans for bolt/lever guns and such.

What do you mean by slim? 1.62, 1.5, or even smaller?

The slimmest I can find.... Looking at the numbers, definitely under 1.4", but actually maybe smaller.
Because of that, I'm thinking that this project idea isn't going to work in .300blk, and I might be changing over to 9mm. That would give me more flexibility, but also because of the bore height of the specific platforms I'm looking at, would give me probably up to almost 1.5", which would be much better

So yeah, I'm still looking for info about slim .300blk cans, but I don't think that this will work anyhow.

Some of the 9mm pistol suppressors are rated for 300 blackout subsonic.  Few are supers rated. Diameters are usually 1.375” or close to that.  I doubt you’ll find a 30 cal suppressor that’s less than 1.5” diameter, that I’m aware of.  

The Canik void 9 is rated for 300 blackout supers from a 8” barrel and has a diameter of 1.375”.

Ok thanks. Looks like that Canik Void-9 is the slimmest so far, at 1.375. If I can make it work, I'll try it, but we'll see. I'll try to do some more measuring.

The original Silencerco Harvester measures 1.37

ECCO has the Furtivus but it's been out of stock for some time.  TLX might be an option for you?  I think it did fairly well at the summit on Blackout.  I have one, but haven't tried it on either of my .300s

Furtivus- In stock when?

I got tired of waiting and bought a Griffin UL HD .300 for my 30-30.  1.5" od, 6" long and 7 baffles.  Sounds great on 30-30 subs and supers. Should be good on Blk.  I may still buy the Ecco can one day.

Q’s Honey Badger-SD can, although only available with the factory SD or on the secondary market, has a 1.5” diameter and does both subs and supers very well.
