I am looking to buy my first AR. The biggest dilemma that is facing me is the choice of caliber. Obviously, the main stream choice is the 5.56/.223 but I am really interested in the .300 Blackout because of the larger size of the round and the perceived greater stopping power. The AR I am drawn to the most is the Smith & Wesson M&P 15 Sport because of the price and I am a S&W fan. That rifle compared to an AR in .300 is a difference of around $1,000 from what I have been able to find. My question is, do you think that it is worth the extra money for the larger round or should I go with the cheaper option? I plan on using the rifle for home defense and of course range time. Do you think that I should buy a rifle in 5.56 and then possibly at a later time purchase a .300 upper? I am not sure if this will impact your suggestion but I also plan on putting a suppressor on my rifle at some point. Thank you for your help.
