I was in a gun shop the other day kind of looking for a 308 on an AR platform. The shop owner took me aside and asked if I was set on the 308, if not then he had an option that I may be interested in. He showed me a S&W MP in 300 AAC Blackout, it looked very interesting. So I thought I would jump on here and ask what you guys think of the round. I have read a bit of stuff on the round but not a ton as I just did this on Saturday and have been working since. So I would appreciate any input as to weather or not this would be a good round or not. It would be for plinking and also as a home defender if needed. I do already have an AR and like it a lot, was thinking of giving it to the wife and then getting another gun. Thanks in advance for the help.
