L3I CZ 457 BILLET ALUMINUM .22 LR 10-ROUND MAGAZINE
Billet Feed Lips. Match-Day Reliability.
The L3i CZ 457 10-Round Magazine is CNC-machined from 6061-T6 billet aluminum with solid aluminum feed lips that hold their geometry, a precision anti-tilt steel follower and a compact, flush-fit profile. Finished in matte black Type III hardcoat and made in the USA, it's built for the shooters who run the CZ 457 hardest.
Polymer magazines flex, wear and drift over thousands of rounds, and inconsistent feeding is the last thing you want on the clock. L3i machines this magazine from billet so the feed lips stay where they belong, and the anti-tilt follower presents every round the same way. The 10-round, flush-fit body keeps the rifle compact on barricades and in the field. Use it for: NRL22 and PRS Rimfire, precision target shooting, and any CZ 457 that sees serious round counts.
Built from Billet.
The body is 6061-T6 billet aluminum, CNC-machined and finished in Mil-Spec Type III hardcoat anodizing. The solid aluminum feed lips are designed to hold their geometry over extended use, and the anti-tilt steel follower keeps the stack square as it feeds. It fits the CZ 457, 455 and 452 in .22 LR, and it's confirmed with select L3i, MDT, MPA and Foundation chassis. Fitment can vary with aftermarket mag wells and modified catches.
