308 build question

Ok, this may be a dumb question, but I figured that I would ask anyway. I am building a 308 DPMS pattern rifle. I plan to use a 20” barrel with a rifle length gas system. Can I use a collapsable stock with a carbine buffer tube with a rifle length gas system, or do I need a rifle length buffer tube for everything to function properly? Thanks in advance, and apologies for the newb question.
