Modular .22LR magazine for AR rifles

In Case You Needed a Bigger Stick

For when you need to let others do the speaking, the Square Deal offers reliability without compromising on capacity, carry weight, or style. This modular .22LR magazine for AR pattern rifles is perfect for builders who need a little more (or a little less) from their kits.

A respected developer within the Black Lotus Coalition, Max’s work has been celebrated for being reliable, durable and convenient for builders of all skill levels.
