The best mag-release - Battle Arms Development AR Magazine Release Part Kit 1

I bought my first one for my B.A.D. lower receiver. I liked it so much, I bought another for my other rifle. I love the closed look of the mag release button, and unlike other company's (Seekinz), it doesn't stick out more than the standard mil-spec buttons. The mag-release itself is a better looking option than other mil-spec mag releases. All and all, it is a great product.
