K baffles are so 1980’s. The cool thing these days are turbine silencers, like OSS has been producing for a while now. The biggest problem with their design is that the cans are massive and heavy, something that isn’t very good for operational operators operating in the area of operations. NEXGEN Defense thinks they have a better zero back-pressure solution: the MAXFLO 3D.
There’s two things that make this can interesting, and thanks to a little Vanna White esque modeling by Scott of this 3D printed model you can see both of them.
First up is the baffle design. Much like an integral silencer design there’s a central tube which is ported on the sides and vents into an expansion chamber surrounding the barrel. This allows the gasses to expand and cool without leaving the confines of the can, reducing the noise and light signature of the gun.
Noticeably absent are what we would commonly consider baffles. Instead of sealed chambers the expansion area snakes its way along the sides of the can and vents towards the front where nifty change #2 sits. Instead of using as small an exit hole as possible the expanded gasses vent through rather large openings surrounding the muzzle of the can, allowing the gasses to flow much faster than otherwise possible. This design reduces back-pressure, which similarly reduces cyclic rate for full auto firearms.
MSRP on the can is unannounced, but I can’t wait to get my hands on one and check it out.
