1st time AR build - Lower Quality Question
I have made the decision after tons of reading and research to build my first AR. As a newbie I'm probably only going to build the lower and buy a completed upper. My question is I see that everyone and their brother makes a stripped lower and I can't seem to tell the difference from one to the other. Why would I spend $200 on a Spikes when I can buy a PSA for $100? I get the price variation on the uppers but can't for the life of me understand the huge price differences when it comes to lowers. Any input would be greatly appreciated.
