I'm going to be purchasing a M4 type of AR at the end of the month. I do not have the money to purchase a Colt, but I spent a great deal of time with my issued Colt in Iraq and loved it to death. I'm looking for a reliable quality AR (preferable one that will have no problem with cheaper ammo). Right now I am between getting a S&W M&P15 or a Bushmaster, but these are be no means the only I am considering. . I will be shooting mainly 62 and 55 grain rounds. The uses for this rifle will be mainly plinking and small game hunting. I am not going to build my own because I am gettinng a military discount that makes it just as expensive to purchase an AR whole with a warranty. I have never owned a civillian M4 type AR, and I need some advice one what you experienced shooters recomend.
