Why Choose the MDT .338 LM 5-Round AICS Magazine
Magnum-Caliber Feed Geometry
Tuned feed lips and internal geometry are built for .338 Lapua Magnum cartridge dimensions, presenting rounds at the correct height and angle for positive bolt pick-up and smooth chambering—shot after shot.
Field-Ready 5-Round Capacity
The low-profile body minimizes interference with bipods, rear bags, tripods, and natural terrain, making it perfect for prone and positional long-range work.
Rugged, Weather-Resistant Construction
A durable metal body with a black corrosion-resistant finish withstands rain, dust, and transport abuse, preserving feed geometry and longevity.
AICS Long-Action Compatibility
Designed for AICS-pattern long-action mag wells used across premium chassis systems and bottom metals built for magnum cartridges.*
Smooth, Reliable Follower
The low-friction follower and quality spring keep stacks even and maintain reliable last-round feeding, essential for ELR stages and high-value hunting shots.
*Always verify your rifle’s mag-well length specification (e.g., 3.715", 3.850" or magnum-specific AICS cuts) and bottom-metal compatibility before purchase.
Ideal Use Cases
ELR & Long-Range Training: Consistent cycling when you’re building dope and pushing past 1,000 yards.
Backcountry & Big-Game Hunting: Compact profile for crawling into position and shooting from sticks or bipods.
Match/Field Steel: Dependable feeding under time pressure across prone and barricade-style positions.
Load Development: Reliable stacking while testing heavy, high-BC bullets and seating depths.
Fit & Compatibility Notes
Platform: AICS-pattern long-action magazine wells designed for magnum cartridges.
Rifles/Chassis: Works with many MDT, KRG, XLR, MPA, and other AICS-compatible long-action chassis/bottom metals supporting .338 Lapua Magnum.
COAL & Bullet Profiles: Confirm your overall length (COAL) and ogive shape; extremely long seating or ultra-heavy bullets may exceed internal mag length.
Not For: Short-action AICS systems or non-AICS proprietary mag wells.

Pro Tips for Best Performance
Verify Your Mag-Well Spec: Confirm your chassis/bottom metal supports AICS long action (magnum) dimensions and the correct overall length standard.
Torque to Spec: Proper action and bottom-metal torque ensures correct mag catch height and optimal feeding angle.
Cycle Dummy Rounds: Before live fire, validate COAL and bullet-ogive clearance to burnish feed paths and confirm smooth cycling.
Keep It Clean: Wipe feed lips and follower occasionally; a light dry-film lube can help in dusty environments.
Seat Rounds Rearward: Press rounds firmly to the rear while loading to maintain consistent stack geometry.
Frequently Asked Questions
Q: Will this mag fit any AICS long action?
A: It is designed for AICS-pattern long actions set up for magnum cartridges. Some systems require specific mag lengths (e.g., 3.715"/3.850"); check your chassis/bottom metal spec before ordering.
Q: Can I run other magnum cartridges?
A: The magazine is tuned for .338 Lapua Magnum. Other magnum rounds may differ in geometry—function-test your specific cartridge and seating depth.
Q: Metal or polymer?
A: Metal body for durability and long-term feed-lip stability under magnum recoil.
Q: Is 5 rounds enough for prone stages?
A: For ELR practice and hunting, five provides a compact, snag-free profile with sufficient capacity for most strings. For higher round counts, carry a second mag.
