because its too much gas into the bcg and to offset that you need heavier buffers or buffer springs or smaller gas port. beats the snot out of the parts a little more breakages are more likely of key parts in the bcg.
your 14.5 the difference between the mid length and carbine length as in how soft yours shoots is that much again with a 16" barrel in a carbine gas layout. its the opposite of what your experiencing.
if a barrel maker goes out of the way to port a barrel correctly for a 16" and carbine length it will work well. but that is almost never the case. you can alos get around the over gassing with an adjustable gas block.
carbine length was designed for the 14.5 barrel. lots of barrel makers found it easier to just drill 16" non nfa barrels for the carbine length than puzzle out a new design that works correctly with the 16" barrel which eventually happened with the midlength system
