I have built ARs in 5.56, 7.62x39, 5.45x39, and 300 Blackout. I like them all for different reasons but recently I converted a Saiga AK 308 rifle from a sporter config to a 922r compliant rifle. The Saiga in 308 is a great rifle. I love shooting 308 but I prefer the AR platform, so a logical move is to a 308 AR. I was listening to AR-15 podcast from FRN and this forum was mentioned. Hope to learn a lot from you all. I will post some pics when I get it done. The lower is completed. Just waiting on the bcg and barrel to finish the rifle.
