The specs look great and the price is good plus I've heard from many online folks I trust that Addax Tactical is a good vendor. But I'd rather know who made the BCG like MJ said because I'd only buy BCM, DD, Colt or LMT. I suspect that's exactly what this would be but I'd want to know.
Lately quality BCGs have been harder to get which may be the reason for the 20 day disclaimer.
The biggest issue with assembling an AR isn't so much getting the parts together right - it's getting the right parts together.
