Well, thanks to all you I am going to get another AR soon . I most likely will be going with a BCM M4 16inch Upper. http://www.bravocompanyusa.com/BCM-M4-16-Upper-Receiver-Group-p/bcm-urg-m4-16.htm Then possibly ordering a BCM, Spikes or PSA Lower. Some of the other manufacturers are out of my budget (LaRue, Noveske, LMT, etc) and this will be an occasional shooter, but I prefer something with reliability and quality in mind. I will plan on keeping it simple, except some Magpul items. Advice on my choices is appreciated.
