Yes, I have jumped on the retro bandwagon. But it’s allowed because I am old. I just recently built this and took it to the range for zero today. It functioned flawlessly. The parts I used are as follows:
Complete upper: TNTE Sales
Lower Receiver: Spikes Tactical
Trigger: Sons Of Liberty Gun works
Lower parts kit: CMMG
Butt stock: B5 Systems
Buffer Tube: Primary Weapons Systems
Buffer & Spring: Palmetto State Armory
Charging Handle: BCM

I used TNTE but they take forever to ship anything. Personally I think the H&R at PSA is a alternative upper you can buy if you want something sooner and a bit correct to the 723 uppers that they actually used in the era you're describing.
