I took the leap. I bought a S&W M&P15 Sport II. Been owning guns and shooting them since 1980. With all the turmoil, rumors and fear being spread in this country. I bought my 1st "black gun" I also bought 5 Magpul gen 2's to go with it. I am going to buy 5 more. Been thinking about the aluminum ones. Are the aluminum mags just as good? Also bought 2k of ammo. What is a realistic amount of 5.56 to keep on hand for reserve? And are 11 mags a solid amount to have. Dont plan to shoot more than 1000 rounds a year out of it.
