Lots of threads on AR's lately, which reminded me to post this poll. With a nod to @DarkLight who first brought up the point, I ask the monkey tree - is an AR lower made of 7075 Aluminum superior to one made from 6061? Assume T6 temper, same manufacturing methods, and everything else held constant. This is part of an ongoing search for opinions on AR lowers, and the first poll (billet vs forged lowers) can be found here: AR lower receivers - a question | Survival Monkey Forums Results of this poll may also influence the direction of another AR thread (not specific to receivers) that I started earlier today, in which we ask by what standards should we judge an AR and why? So, this thread serves a dual purpose of determining the merits of materials used to manufacture a lower, (and public opinion on the subject,) and possibly also to serve the purpose of identifying a standard to which AR's in general should be held. Thanks in advance, I'm looking forward to the results. Enjoy!
