If you want to shed weight, I would recommend using an upper without the Forward Assist (something I hate anyway), versus cutting weight on the bolt carrier. The lighter carrier weight could be balanced with a stronger recoil spring, but I prefer leaving things with the operating system as close to optimum and proven as possible.
You can get uppers that are in every way like a flat-top upper, with ejection port and brass deflector, minus the forward assist from Les Baer.
