White Sound Defense is introducing a new muzzle device for the AR-15 called the FOSSA-556. It is a device that WSD promises will reduce flash, eliminate muzzle rise, and reduce recoil all without increasing concussion or noise (including that annoying pitch fork ringing that some pronged devices exhibit).
The FOSSA-556 is made from 17-4PH stainless steel with a titanium aluminum nitride surface coating. This should make it very resistant to corrosion and adhesion of carbon. I have really come to appreciate WSD’s approach to choosing materials and coatings without compromise.
As usual, there is a ton of great ancillary information about the device, its design, and application on WhiteSoundDefense.com. I have one of these inbound for review.
