MDT AICS 300 Win Mag magazine delivers dependable feeding for long-action AICS rifles with the 3.85″ pattern and a practical 5-round capacity suited to range work and hunts.

What it does

This magazine focuses on consistency from the first round to the last. Rounds present at a stable feed angle and cycle cleanly into the chamber. Moreover, the 5-round format keeps the profile trim for prone and barricade positions. Handling is positive at the bench and in the field. Loading is straightforward and predictable. Maintenance is simple and does not require special steps.

Fit & Compatibility

Designed for long-action AICS-pattern (3.85″) setups, this model supports .300 Winchester Magnum. Use it only with the platform and cartridge listed here. If your rifle uses AICS bottom metal or a compatible chassis, latch and feed geometry should align correctly. Therefore, verify smooth chambering with your chosen bullet profile and COAL during test fire before match day or a hunt.

Why shooters choose the MDT AICS 300 Win Mag magazine

Reliability builds confidence when wind calls and trigger control matter. The 5-round capacity balances uptime with low bulk, so it rides cleanly in a pouch and stays out of the way when you go prone. Additionally, the compact footprint helps maintain rifle balance for supported or improvised positions. Ultimately, dependable cycling lets you focus on data, dope, and execution rather than managing stoppages.

Range and field notes

For practice sessions, the MDT 300 Win Mag magazine reduces top-offs and supports a steady cadence through zero checks and dope verification. Moreover, consistent stack geometry helps you evaluate ammunition lots and seating depths without interruptions. Keep feed lips free of debris, confirm positive seating with a firm push, and you’re ready to run drills or head into the field with confidence.
