Luke ( @BallisticAviation) is hanging out with Seth from KCI to talk about their new KCI PC Magazine. Their new standard capacity magazines are constructed from a proprietary polycarbonate formula, with patented stainless steel internal feed lips, a stainless steel extra-powered spring, and an anti-tilt follower. The transparent opaque design with dual round count markings allows for visible round count confirmation from any side and the unique internal steel feed lip design keeps the magazines in working condition during harsh use.
