So for example I am going to buy this completed lower: https://palmettostatearmory.com/bla...r15-complete-moe-ept-stealth-lower-black.html
However I want to turn my AR into a 5.56 pistol, so would this upper work: https://palmettostatearmory.com/psa-10-5-5-56-1-7-nitride-upper-w-o-bcg-or-ch-507020.html ? I'm honestly confused on how I can turn it into a pistol. Would it be the lower that is responsible for that or the upper? Lastly if I did want to buy both the upper and lowers I have linked above, would they be compatible with each other? Thank you for any advice, as I will be ordering them tonight.
