SGM Tactical AR-15 Magazine .223 Rem/5.56 NATO 100 Rounds Black Nylon Pouch Korean Made SGMTAR15DC

I haven't shot much with this but I have had 0 failures. I also have the surefire 100 round mag too. On weekends I like to bring my riffle out and set it up on my coffee table. With a surefire mag, it won't sit properly on the table, but with this drum style, it sits nice. I would recommend this to anyone with an AR15.
