Very, very nice...

Is that what you guys call a lower?

It doesn't look like you are too far away from completing it.. mainly a barrel left... no doubt the most expensive part...

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"



These upper and lower receivers are what is call "billet" as compared to "forged" receivers. They are machined out of a block of aluminum.

Go to this thread to see the process in photos of Quentin Defense making the ************** billet lower.

Here is my AR. Its a Bushmaster in .223. 20" HBAR, 1:8 barrel. I put a Timney 4# skeleton trigger in it and a DPMS free float fore end out front. Burris Fullfield II clamped in a Burris P.E.P.R. And MagPul 20rd PMags. As for ammo I load my own. My ammo replicates the MK262 MOD 0 military long range ammo. Topping with Sierra 77gr HPBT match bullets. Its my long range coyote undertaker.

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...

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... :(

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..

Nice setup, how long did it take you to get the Emerson CQC-7?
I ordered it about 2 years ago and got it in a week or so, didn't take long. Are they hard to come by now? I wish I could remember who I ordered it from.

I'm pretty sure I got it in 07 or early 08, I guess they were easier to find then. I remember having to search around alot before I found somebody that had them in stock, for a reasonable price.
