Are pistol and rifle buffer tubes different?

Rifle buffer tubes are very basic when compared to a carbine or pistol tube. The rifle tubes are longer and don't have a slot for an endplate, which is not used with rifle-length, fixed stocks. The stock will secure the rear take-down spring once installed.

A concentric pistol buffer tube cannot accept a rifle stock, but most will receive an arm brace.
