What brands of 80% lowers have you had good luck with or more importantly are there any brands that should be stayed away from with respect to there quality?
Any opinions on best brand of AR-15 80% lower (6061 or 7075)?

I bought a bunch from right to bear arms website . Screwed up 2 thanks to a router but finished 2 and a buddy finished 1 and they both work great

Several threads of varying direct usefulness to your question, but try this one:

Andersen's at one time needed the rear shelf fully milled even though the lowers are shipped that way.
Tactical Machining needed no additional milling.

Other than the buffer tube thread fit I haven't had trouble from any lower. You can dry fit everything except the trigger group before machining to see if it'll fit your upper.

Not sure, but I believe Cerro Forge is a prime vendor for Colt.
I believe that is correct. You can find them for $40 (unanodized) if you look around.

Thundertactical.com is another good place to get 80 percent lower receivers. Their 5 pack is a decent deal. The only thing is, you are guaranteed either Cerro or Brass Aluminum. You cannot pick. Mine came in as Cerro Forge which made me happy. I agree with the above comments. 7075 T6 is the way to go. You get a nice smooth finish after milling the pockets. Cerro sells to Colt, Spikes Tactical, Daniel Defense, DPMS, Bushmaster as well as others. Brass aluminum has a square forge mark. I am not too sure which firearm manufacturers they sell to. One of my registered Spikes Tactical receivers has the typical Cerro keyhole forge mark on it. I have been told to stay away from CAST LOWER receivers as they are supposedly the weakest of the bunch. I have steered away from polymer lowers as well. Why save 5 or 10 bucks when you can spend that little bit of extra and get a strong 7075 T6 aluminum receiver? Especially for the amount of time that you are going to put into milling and building your lower. I will save weight somewhere else, not in the receiver. Most importantly.... HAVE FUN BUILDING!

I like New Frontier Armory. They make 9mm, AR-10 and AR-15 80% billets and AR-15 forged. They all seem to work very well.
Yes. Love their 9mm offerings. Have done 3.

When I was Manufacturing ARs in a different life I used to use New Frontier Armory to make my variance lowers. The President is a Veteran and a great guy. They make a quality product at a good price and stand behind it.
