I am looking to purchase 3 AR's in the foreseable future. I want to purchase the equivalent to Rock River Arm LAR-15 Standard A4 Model. I will be equiping them with red dot optics and the detachable carry handle and 8 magazines each. The LGS all have their favorite brands. The 3 names that keep coming up are Rock River Arms, DPMS and Bushmaster. I already own one Bushmaster and I am happy with it. These rifles will be for my family members in case the SHTF. I have a local support group in case the SHTF and we have standardized on 5.56 Nato for our common rifle and .45 ACP for pistol. Most of us have AR and 1911 platforms But what are your thoughts, input and ideas on the matter?
