Wasn’t the forward assist button added to subsequent production runs in order to help the bolt properly feed and seat the round manufactured with the lower grade powder? I believe the rationale was that there had been millions of rounds made with the LG powder and that it would be more cost efficient to alter the production runs than to recall and replace the existing ammo stocks.

I believe they also added a coating to the chamber of some teflon type material that helped resist the caking of carbon.
The m4 is after my time...I trained and operated with an mp-5 and the meusoc m1911 back in the early 90's. Every member of a breeching team had an identical rig. One man in the team carried an mp-5sd (suppressed mp-5 which used subsonic rounds) and another complimented his gear with a 12guage. We had room for personalization but few variations were employed. We operated like we trained, and we trained with what we were provided, weapons wise.
