Just wondering if USSS ever used the 5.56 MAMS? Was thinking of swapping muzzle devices and mounting a MAMS I have, but have also considered keeping it as clone correct as possible.

I don't have extensive knowledge of the USSS SR-16 so I'd appreciate any feedback or knowledge.

Also, from accuracy and overall use, what is the better muzzle device in your opinion, MAMS or FH? Accuracy and Control.

That said, I have not run any 5.56 program that involved anything other than the 3-prong flash hider, with some limited use of the QDC Open Brake for suppressor longevity under aggressive firing schedules with short barreled rifles and frangible ammunition.
The 5.56 CRS-2 works fine with a Mini-MAMS, with some minor performance shifts due to the altered pressure flow through the muzzle device and into the primary blast chamber of the suppressor, but nothing drastic.
As far as dispersion and felt recoil, there is virtually no difference once the can is on, though the MAMS will show slightly more residual bore pressure.
