L3i CZ 457 10-Round Billet Aluminum Magazine
The L3i CZ 457 10-Round Billet Aluminum Magazine brings precision-machined construction and competition-focused engineering to the traditional 10-round rimfire magazine. Manufactured in the USA from solid 6061-T6 billet aluminum, this premium .22 LR magazine features a Mil-Spec Type III hardcoat anodized finish, a precision steel follower, and a compact profile designed for competitive shooting.
Designed for compatible CZ 457, CZ 455, and CZ 452 rifles, the L3i 10-round magazine offers a durable alternative to conventional factory polymer magazines. Its rigid aluminum body and precision-machined feeding geometry are engineered to maintain consistent cartridge presentation through repeated use.
For PRS Rimfire, NRL22, and precision target shooting, the shorter 10-round configuration offers practical advantages. Its compact profile reduces magazine protrusion compared with extended-capacity designs, making it particularly appealing for shooters working from barricades, shooting bags, and supported positions where clearance matters.
Precision feeding starts with precise geometry. L3i incorporates an anti-tilt steel follower and carefully engineered cartridge presentation to promote smooth bolt cycling while reducing unnecessary contact with exposed lead bullet noses. The solid aluminum construction also provides durable feed lips designed to maintain their geometry over extended use.
Finished in matte black Type III hardcoat anodizing, the L3i magazine combines a clean appearance with the durability and dimensional consistency expected from a premium competition component. For shooters who want the familiar 10-round capacity without settling for a conventional plastic magazine, it's a compelling upgrade.

Will the L3i 10-round magazine fit CZ 455 and CZ 452 rifles?
Yes. L3i specifies compatibility with CZ 457, CZ 455, and CZ 452 rifles chambered in .22 LR. Modified magazine catches and aftermarket magwells may affect individual fitment.
What makes the L3i billet magazine different from a factory CZ magazine?
The L3i magazine features a CNC-machined 6061-T6 aluminum body, Type III hardcoat finish, precision anti-tilt steel follower, and competition-focused feeding geometry. These features distinguish it from conventional factory polymer magazine designs.
Should I choose the L3i 10-round or 13-round magazine?
The 10-round magazine offers a compact profile with less protrusion, making it attractive for positional shooting, supported rifle positions, and applications where magazine capacity is restricted to 10 rounds.
The 13-round version provides three additional rounds for longer competition stages where that capacity is permitted.
