Group buy sign-up at viewtopic.php?f=87&t=74825

I think we have a consensus. Anderson Rifles it is.

Stay tuned. I will be in touch with them and will have a final price - to include shipping - shortly.

From the other things I've read, you can't provide (direct?) help, but what if there was a video on the internet showing the steps on how to finish it with a CNC machine similar or exact model to yours?

My current understanding is that each person would have to write their own G Code, connect with their computer and use their own licensed CAM software. I can give a definitive answer once I've heard back from the ATF.

It does matter. Finishing a lower from a forging can be a difficult undertaking. If they are cut incorrectly the tolerances of the finished receiver can be too far off. I chose those 4 because they had enough good reviews that I was confident we'd get a good product. I personally voted for Anderson, but I wanted everybody to know what else was available. Informed choice, you could call it.

Whereabouts in Austin?

North of Austin, probably 45 minutes from Franklins if you factor in traffic. I don't like posting where I live publicly, so specifics will be distributed by PM when it's time for the build party.

The only hit against Anderson was some shill marketing 4 years ago over on ar15.com. Their product has reasonably good reviews, and all AR15 forgings come from a small number of manufacturers, so no matter who does the 80% of finishing they all start with good quality.

Ladies and Gents,

Between the forum and some other people I know, it looks like there is enough interest to move forward with a group buy.

After some hours of research, I have narrowed down the list of potentials to 4. Each link is directly to the chosen lower.

Anderson Rifles
Ares Armor
Colfax Tactial
Right to Bear Arms and Supply

I had planned on simply making a decision and moving forward, but I'd rather let the interested parties decide. All of the lowers will come "in the raw," meaning no finish has been applied. I will offer my equipment for Duracoating to those interested, and of course, I am still planning on hosting one or more build parties. All of the lowers will require the same amount of work to finish them. Of the four options, there are only two major differences.

#1 - Forged vs. Billet
Three of the lowers (Anderson, Colfax and RTBAAS) are forged lower receivers. This means a billet of aluminum is heated until it is soft enough to be forced into a mold at high pressure. It is different from casting, since the metal isn't melted in forging.

Ares is CNC machined from a forged billet.

I have no dog in this fight. Cast, Forged and Billet lowers are all more than strong enough to support the AR15 design.

#2 - Three options (Anderson, Colfax and RTBAAS) are essentially mil-spec, and have ears machined for a trigger guard to be added. Ares has an integrated trigger guard CNC machined with the rest of the receiver.

I have been able to speak to Anderson, Colfax and RTBAAS to get group pricing information. Ares hasn't returned my calls or emails yet, but they've only had a few days. I'll still give them time to offer a better price.

Anderson has offered $40 per lower.
RTBAAS has offered $48 per lower.
Colfax has offered $70 per lower.
Ares "sale" price is $69.92 per lower.
