It is CNC machined using high-quality lightweight aluminum alloy and topped off with a durable anodized finish. The magazine extension adds 4 more rounds to a standard M18 magazine and serves as a purely aesthetic upgrade for the M17 magazine, which retains its original 24-round capacity. It is a simple drop-in installation and does not require modifications to ensure proper fitment and installation.
