Thank you Doc!
This is the preliminary page for ordering http://store.ar15.com/store/product.html?cat=9&prod=279
Before anyone's shocked by the price, we did some price shopping and math:
Norgon ambi mag release: $90
Battle Arms Dev. 45 degree selector: $85
Geissele 3 gun trigger (not the ar15.com special 4.5lb, that's an ar15.com exclusive): $230
Magpul CTR stock: $92
We're up to $532 so far, this doesn't include the other lower parts such as left side mag catch, receiver extension, front and rear take down pins, etc.
If I were to build a rifle with identical specs with a forged receiver (that's not a billet, Magpul-ar15.com collaboration receiver with the right side bolt release), I'd be approaching $700 and climbing.
Speaking of Magpul, ar15.com purchased the rights to the super rare Magpul receiver design, thus the family resemblance.
BTW, they will make it CA compliant for CA customers
