The AREX Delta L/X Magazine is constructed as a factory OEM unit engineered specifically for the AREX Delta L and Delta X platforms, ensuring a perfect fit and seamless drop-free operation without modification or fitting required across both full-size and compact Delta configurations. The +2 extension base pad increases the standard 17-round capacity to a full 19 rounds, providing meaningful additional ammunition on tap for duty, competition, and defensive applications without requiring an aftermarket magazine or base pad purchase.
