Interesting Thread.
A quick internet search revealed many illustrations of the marked differences in the BCG's.

The internet is a great place to get info as long as you don't believe everything you read or see. It used to be "I will believe it when I see it" Photo Shop put a end to that. Then along came video editing so you can't even believe You Tube.

Off hand, I can think of 5 different variations of the BCG, and the number is likely double that.
I do prefer the original design, and will stick with the full auto version for the increased mass and tamer recoil pulse.
Did this on my sport with the same exact result. Felt recoil is less as well, just a little but less.
Many big name civilian AR makers (Smith and Wesson) will over gase their rifles (larger gas port) to make sure they shoot everything, like weak powered steal cased ammo. It is less calls they will get. A 16inch carbine will be even more over gassed because of the longer dwell time.
A full auto BCG is only .5 ounces heavier than a SA. I weighed my Sport SA BCG and my new BCM FA BCG. Adding a H buffer 3.8 ounces by replacing the carbine buffer 2.9 ounces adds a tad more weight as well. Over all the combo is less than two ounces but it tames the recoil a bit on over gassed AR's.
I personally would not go higher than a H buffer and while I do change out the spring with a chrome silicon based spring (for much longer life) I dont change the spring tension. Too heavy of a buffer and or spring will possibly cause FTE or FTL problems.
