And i usually dont get tangled up in semantics too much. And i am not trying to discredit Mr. Duecks expertiece in any way.

Tuukka:
All I can tell you is that when I have fired the M-4 with the SureFire suppressor, I can hear the bolt cycling and the trigger resetting. I have never observed that with the same weapon and ammo, but no suppressor. The proximity and conduction of sound may be the cause, but nevertheless, the fact that you can hear the action cycling when shooting with the can remains.
My experience may be limited, I have only fired a hundred thousand rounds or so through M-4s and a couple thousand through the SureFire suppressor.
The suppressor is rated at a measured 27-30 dB (A) SPL of suppression, what are you allowing?
