I'm interested in everyone's experiences with AR-10's and LR-308's as well as the other AR style 308 variants. I purchased a LR-308 lower as a gift for my brother who was craving a .308 and now I wish I had one as he loves his. But the more I've researched it for myself the more I'm at a quandary as to what I want to purchase. And significant differences, (besides some indication of magazines or those such as the POF and similar piston 308 models). Which have you used, which do you like, or which would you recommend and why? I really think that I would like to make this my primary AR platform but I'll withhold my final judgment until all the votes are in!
