The Implications of MFMD Style/ "High Performance Reduced Length" (HPRL) suppressors.
There has been a lot of buzz about the Strategic Sciences Multi Function Muzzle Device (MFMD) suppressor series, notably for their alien aesthetics, somewhat less for their supposedly stellar performance, but what I don't see discussed as much is their reduction in OAL and the implications of that.

On an 11.5 URGI an MFMD 1.3 adds less than 2/3rd of an inch

An RC-2 adds about 3.8, this means you can now have a 15.3in Barrel with an MFMD for the same overall length, that means higher velocities, less flash (especially so with a theoretical optimized MFMD, which is possible because they're all platform optimized), less concussion. This coupled with high performance ammunition such as NAS-3 would either allow you to have even higher velocities or the same velocities while shaving off length.
I don't think SS can patent the concept of a direct thread reflex suppressor no matter how fancy it is, so assuming the the MFMD's perform as advertised I think HPRL as a category could emerge.
This is what the NGSW program should have been, this concept applied to a high end AR.
