I see that AIM Surplus has CMMG lowers. Anyone have any good or bad opinion about the lowers? I've built 4 so far on PWA receivers and I need to do two more to pass down to my kids in 10 years. I sold 2 and need to re-stock.
Also, if anyone knows a source for good available lowers, please let me know. I was very impressed with DPMS lowers, looked nice, but wasn't mine. I'm not patient enough to wait months for those.
