Thanks QtrHorse. I started worrying that a rifle length upper wouldn't function properly. I have used a 20" upper assembly but I used a rifle length buffer tube etc. I have never tried to use a rifle length upper on a lower built for a carbine.

Depending on the ammo you prefer to use and the gas port size, you may have to try out a different buffer weight. My rifle gas 18in upper (BA SPR Wylde barrel) runs fine with a H buffer.
