KCI USA AR-15 30-Round Polymer Magazine - Model KCI-MZ065

The KCI USA AR-15 30-round polymer magazine delivers dependable capacity for modern sporting rifle shooters who demand reliable feeding without the weight penalty of steel. Built from a proprietary polycarbonate formula, this magazine pairs durable construction with practical design details: stainless steel feed lips that won't degrade with repeated use, a heavy-duty stainless spring, and an anti-tilt follower that keeps rounds feeding straight and true from the first shot to the last. Whether you're running drills at the range or stocking up for hunting season, this is no-frills ammunition storage that gets the job done.

Round count is one of those details you'll appreciate on a mag—especially when you're deep in a stage or managing multiple loads in the field. The dual round count markings let you see your capacity from either side of the magazine, and the semi-transparent body means you can verify what you've got loaded at a glance. The textured grip surface isn't just there for show; it makes indexing and manipulation smoother when you're moving fast or working with gloves.

KCI USA mags are engineered for AR-15, M16, and M4 platforms, so if you're running a standard direct-impingement rifle or carbine, this magazine will integrate seamlessly into your setup. It's the kind of accessory that doesn't demand attention—it just works, cycle after cycle, day after day.
