I am planning another build. This time I want to go the extra mile and also I want something with an A3 upper, as both my 20 and 16 incher have A2 uppers. My question is, I have been seeing these Stinger Arms forged Lowers for like $89.00. Should I try them out, or just go with Oly like I did my last one. Even my Oly lower needed a little fine-tuning when I first got it. Am I right in the assumption that there can't be much difference in lowers besides the cast/ forged thing?

Go with the Stinger Arms/Mega lower.  I have two and they are noticeably nicer than some of my other "big name" lowers.  Here's a link that has plenty of pictures: [url]http://www.ar15.com/forums/topic.html?b=7&f=21&t=153544[/url]
