Which billet lowers meet the following criteria
I'm trying to find an AR-15 lower with some particular features:
- 7075-T6
- Integrated trigger guard
- Threaded bolt catch pin
ETA: I spoke with someone at Quentin Defense and they are using 6061-T6, so that counts them out.Last edited by AR-10; 21 March 2011 at 10:30.

Why the 7075-T6 requirement?

Tactical Innovation, Seekins Gen II and the Mega lowers are. The Seekins has an ambi bolt release and you can get the Mega that way as well.

I called Mega and was told that only the billet receivers with ambi controls come with a threaded pin, the standard billet lower takes a roll pin.
This is not for one of my own builds, I am simply finding all of the parts needed to build it into a complete rifle - the guy that is putting it together wants a 7075-T6 receiver that he can build without a hammer or punches.
It's looking like such a product does not currently exist so he's gonna have to live with an alternative.

I missed the threaded bolt catch pin. Tactial Innovations have roll pins.

This one is meant to pair with Mega's uppers specifically:

The Spikes Tactical Biohazard would be good but you cant just buy the lower, its a combo upper/lower
