Why Choose an AX AICS-Pattern Magazine for .338 Lapua?
Proven feed geometry: The AICS/AX architecture manages long, heavy, high-BC bullets with smooth pick-up and nose guidance, reducing nose-dive and bolt-over issues common to big magnums.
Magnum-ready durability: Built to withstand recoil impulse, field grit, and hard use with a stout body, tuned feed lips, and a high-tension spring for consistent rise.
Precision-friendly stack: An anti-tilt follower supports uniform cartridge presentation—critical for repeatable bolt feel and consistent chambering from prone, barricade, or off-angle positions.
Corrosion-resistant finish: A protective exterior coating shrugs off moisture, rain, and condensation—ideal for backcountry hunts and wet match days.
AICS/AX compatibility: Integrates with AICS/AX-pattern chassis and bottom metals built for .338 Lapua Magnum (verify your specific action/chassis).

Confidence for long strings: Consistent feed means fewer interruptions during load development and chronograph work, letting you validate dope accurately.
Field-trustworthy build: Robust body and finish resist lip spread and corrosion, sustaining reliable function over seasons of recoil and weather.

Big-game & mountain hunting where dependable follow-up shots matter
Professional/duty applications (where applicable) requiring durable, repeatable feeding under adverse conditions
Ballistic validation—chronograph sessions and dope building with long, heavy .338 bullets
Setup & Fit Checklist
Confirm pattern: Your stock/chassis should specify AICS/AX long-action magnum compatibility for .338 LM.
Check bottom metal: Ensure your DBM accepts AICS/AX .338 LM magazines and that latch height is correct.
Measure COAL: If you handload, confirm your cartridge overall length against the magazine’s internal OAL for reliable clearance and feed path.
Function test: Cycle dummy rounds to verify smooth pick-up, positive bolt-over-rim, and last-round presentation before live fire.
Maintenance Tips
Keep the path clean: After range or field use, brush out the interior body, follower channel, and feed lips to remove grit and unburned powder.
Inspect feed lips: Check for bending or spread. Proper tension keeps presentation correct for big magnums.
Light protectant: A dry-film or light rust inhibitor helps in wet climates without attracting debris.
Rotate if stored loaded: Preserve spring life by rotating magazines when kept loaded for extended periods.

Frequently Asked Questions
Q: Will this magazine work with non-AICS mag wells?
A: Use only with AICS/AX-pattern magnum systems. It won’t fit proprietary magazine inlets not designed for AICS/AX .338 LM mags.

A: It is designed for magnum/CIP-length .338 LM use, but internal OAL varies by model. Measure your load and verify clearance before committing to a specific bullet seating depth.
Q: Do I need to tune the feed lips?
A: Most rifles run out of the box. If you’re pushing very long VLD/ELD bullets or unique ogives, consult a qualified gunsmith for minor tuning.
Q: Which capacity should I pick?
A: 5-round mags are compact and great for prone or hunting. 10-round mags extend capacity for training and competition—choose based on your application and regulations.
Q: Any special maintenance for harsh conditions?
