I am about to buy my first AR. I am not looking to spend a lot so I can stay married. I've been looking at the DPMS Oracle, Bushmaster ORC, and the M&P (all in 5.56). Does anyone have experiences with these guns or helpful advice? I will be using this gun mainly for predator hunting and a little recreational shooting, I won't be putting thousands of rounds through it every year. Thanks in advance and have a blessed new year!!
