If you are you using, what has been your experience?
Did you use a crush washer or spacers?
What were you using before?
Can you tell a difference in the flash?
Recoil?
Muzzle rise?

I have only looked at the pictures so consider my opinion drive by at best. You are probably dreaming if you think it will reduce recoil or jump. Most 3 prongs do pretty good at reducing flash sig but some are known to be better than others. It's probably overkill on a MD like that to use anything other than a crush washer. Why don't you buy one, screw it on and let us know what you think??Quote:

Objectively like other open tine flash hiders (Vortex, BE Meyers, Surefire, AAC, Dead Air, Silencerco, etc) it'll be very effective at eliminating flash, better than a brake or comp on dust signature if you're shooting prone, and will offer negligible recoil or muzzle rise mitigation. For a dedicated flash hider that isn't mounting a suppressor a crush washer typically works best, but it ultimately doesn't matter that much. The Vortex G6 is nice in that you don't need washers or shims of any kind, as the design of it is self-tightening.
Regarding a "difference in flash," compared to what? If you're comparing to a bare muzzle then sure, it'll be night and day. But, compared to something like an A2 flash hider it won't be as noticeable unless it's on a shorter barrel. The FCD 6315KM on my 12.5" still occasionally lets loose a fireball when I'm shooting XM193, a very flashy ammo by itself, but isn't an issue at all on my 16" with an A2 flash hider.
I have been using them for awhile and it’s my favorite flash hider. Below is a review of it.
https://youtu.be/bpy4DEMrd2M
I have had one pinned on a 14.5 barrel since around 2013. Compared to an identical barrel with a pinned a2x it had noticeably less subjective muzzle rise. I believe there is some compensating effect, though granted it is small. Absolutely zero flash comes off that upper shooting in the dark. A2s on 14-16" barrels have mild flash mostly coming up out of the ports. No ringing. In my opinion it is superior to an a2 but whether the weight length and cost are worth it will vary from person to person.
I think I will.Quote:

It is not a three prong version of the Vortex. On the Fossa, the prongs have a reverse taper to force gasses. And the bottom prong is much wider, giving it muzzle rise compensation. It is an exceptional device, but of course, longer than an A2.

I think the price is a little crazy but if that doesn't deter you I would not hesitate to recommend one.
ETA:
Many 3 prong FH have that annoying tuning fork ring to them, the FOSSA does not.
A solid review...

Impressive video!
Well . . . I did!Quote:

This was taken around 1900 with sundown between 1845-1850. It was darker than what the picture would lead you believe. That's why the fireball is so visible.
After seeing the video I had my doubts about the FOSSA.
Two or three days later I returned with the FOSSA 556 installed. Repeated the same scenario at about the same time and I swear the fireball was gone!
Attachment 64204
This frame was pulled from the video at the moment it fired . . . no fireballl!
I'm impressed!
There is supposed to be some compensation since the device is timed but shouldering the rifle I could tell no difference.
At $100-$109 it's expensive but I'm happy!
And I forgot to add . . . no ringing!
I wanted to use the FOSSA. But I was on a backorder for several months and the only thing the distributor could tell me about a timetable was “that’s determined by the manufacturer”, or something to that effect. This was last year before COVID supply issues. I cancelled my order. It seems like the FOSSA is vaporware now.
Say "In stock ready to ship"Quote:

Cool. I went a different route, but that’s a good heads up for others interested.Quote:

Looks like a BCM Gunfighter comp to me. Definitely not an A2.

I have since bought a couple more and "one of these days" intend to have the gunfighter 1 cut off one of my 14.5" BCMs and install the FOSSA so I can do a side-by-side comparison.
I also bought and installed one on a 16" .308 build that I have also run a KAC MAMS on. Recoil reduction was noticeably better on the MAMS, but (and this goes for the 5.56 version too) the FOSSA doesn't generate much if any pressure blast to the sides/rear. On the ground between the concrete walls/legs of the rather narrowly spaced shooting stations the MAMS blast muzzle blast was slapping me so hard I started to feel like I was getting a concussion whereas I never noticed the FOSSA.
Anyone know where these can be bought still. Seems like every where is out of stock.
I've bought them from AT3Tactical and Atlantic Tactical. If they are not in stock I would suggest signing up on their email notification and jumping fast when you get the email.Quote:

What I do know is White Sound Defense ran into a supply issue with the FOSSAs several months ago. They are unable to provide even a rough timeframe as to when they would get more. The last time I spoke with them, they mentioned possibly incorporating some desired design changes into the original FOSSA in which case there will be no more original FOSSAs ever, but hopefully at some point a redesigned version.
The best thing to do is use the "Notify Me When Available" option on the product page so you will be notified when product quantities get updated.

I have a in-the-white (stainless, I think) prototype I can send you for shipping costs. Shoot me a PM if you want it.Quote:
