During the deepest, darkest days of The Great Pandemic I assembled a .308AR using the information on this site. It has operated flawlessly! Many thanks for all the good information. Now would like build another upper, I have on hand a DPMS style upper and bcg, I can get a lightly very used Armalite 16" barrel for a reasonable price. Will this work? What is needed besides AR10 bolt and firing pin if it will work. Are the bolts interchangeable in bcgs? Are barrel extensions interchangeable between the platforms? Bought the receiver ext. spring and buffer directly from Armalite when assembling .308AR, now don't see the option to buy parts on their site. Any information you can share is greatly appreciated. Is this just a dumb idea that would not be worth the effort?
Thank you,
George
