Build and materials: engineered for service

The use of DuPont Zytel polymer gives the PROMAG STANDARD a lightweight yet impact-resistant shell that stands up to drops and field abuse. The full length steel internal insert maintains feed-lip geometry under stress and reduces torsional flex that can cause malfunctions with softer polymer-only designs. An injection molded follower ensures reliable alignment of rounds while the chrome silicone wire spring resists corrosion and preserves consistent spring tension over lengthy storage and repeated cycling.

Periodic disassembly for light cleaning and inspection of the follower and spring will extend service life—avoid abrasive solvents on the polymer body and keep springs lightly oiled to prevent corrosion. Because these magazines are Made in the USA, replacement parts and customer support tend to be more accessible.
