ESPECIALLY ON TAX STAMP BUILDS. The company name is Georgia Aerospace and Defense Manufacturing. This was the first lower I ever bought in January for $200 after the Sandy Hook mess. At the time it was the only lower I could find. I just wanted to get my paperwork in for my SBR ASAP. That was actually good thinking. Look at the exec. orders.
So thinking that since variants of the AR15 have been around since the 60s, the specs are everywhere, and they're apparently printing them now. There's no way a company could screw it up! Boy was I wrong. Saw some posts on the internet bashing their lowers as nothing fit right. And lord behold! Mine didn't either. Catastrophic fit. Luckily the ATF is helping me out and allowing me to change the serial # without losing my place in line.
MORAL OF THE STORY: Stick with the guys who have been doing it for a while!
