Yep, it just needs the barrel assembly and a handguard/free float rail system.
This is what's called the "complete lower"
This is what's called the "stripped lower"
This would be the "upper"
Thanks! That helps a lot...
I have a strange fascination with these black guns... I love my Glock, but these AR series of rifles are the sexiest guns imaginable... It's been a long time since I shot anything that powerful...
These upper and lower receivers are what is call "billet" as compared to "forged" receivers. They are machined out of a block of aluminum.
Thanks... I have an engineering background, so I understand the difference between machining a billet piece of aircraft grade aluminum into a part and forging one.
Unfortunately, I don't know much about AR's...
Go to this thread to see the process in photos of Quentin Defense making the AR15ChatterBox billet lower.
Very nice setup... Good post... Imagine back when a poor machinest would have to sit there and turn the mill handles to create something like that... CAM has changed a lot of things for the better...
The videos didn't seem to work, but all the photos looked good. Thanks for taking the time to post such a detailed reply. I appreciate it..
