I have decades of shooting these platforms. Yes, like I stated, I can tell the difference. But its not enough to matter in terms of changing how you shoot. Your F=Ma (not F=MV^2) is not accounting for the buffer assembly absorbing a large portion of the recoil in the AR platform.
In physics, you don’t get something for nothing. Ever. Even from buffer assemblies.
Buffer assemblies trades the magnitude of the recoil impulse for the length (in time) of the recoil impulse. For most shooters (well, for me and anyone I’ve ever discussed it with), a “shove” recoil is more tolerable than a “slam” recoil.
