No problem with the question, we are all learning. A barrel is not relegated to being used with one system or the other. The only real difference in the gas ports in AR barrels is where they are located how big the manufacture decides to make the whole. This barrel like most AR barrels can be used with either a gas block for a Direct Impingement system or a gas block for a piston system. I chose to run a piston system for a cleaner running gun and for the ability to turn the gas off (an option with the Adams Arms kit) so the gun would operate like a bolt gun. this allowed me to not have to chase brass which due to the rarity and value of grendel brass is especially important. I would simply shoot a round then operate the side charger with my left hand while catching the brass with my right and stowing it in a pocket. You will also hear people argue which is more accurate, gas or piston, but with the system off there would be no disruption to the bolt carrier and therefore in my mind a better option when shooting for accuracy.
The whole upper is available, and in fact that would be my preference in selling that way I don't have to disassemble everything. As a perk to anyone who buys the upper I will throw in a bunch of loaded ammo. I have everything advertised in the classifieds on this site. Let me know if I can answer more questions.
