The Double Stack combines two AR-15 10 round Magpul PMAGs for an overall length similar to a 30 round magazine. It is machined from lightweight aircraft aluminum. The Double Stack can also be used as a weighted butt plate to assist empty mags falling free during reloads. Available in black. PMAGs not included.
