Why Choose This MDT .338 LM Magazine
AICS Long-Action (3.85") Standard: Sized for 3.85" AICS pattern inlets and bottom metals common to modern precision rifles—easy integration with popular long-action chassis.
Magnum-Optimized Geometry: Internal shaping, follower angle, and feed lips are tuned to control the long, heavy .338 Lapua Magnum case for a positive, nose-up presentation and clean chambering.
Rock-Solid Construction: A rigid, corrosion-resistant metal body with a durable black finish resists dents, weather, and hard range/field use.
Match-Ready Reliability: Anti-tilt follower and appropriately tensioned spring help prevent nose-dive and ensure consistent last-round pickup.
Practical 5-Round Capacity: Ideal for prone work, hunting blinds, and match stages that demand reliability without excess bulk.

Compatibility & Fit Guidance
Chassis & Bottom Metals: Designed for AICS-pattern long action (3.85") systems from MDT and many other manufacturers. Verify your stock/chassis inlet and mag-catch height.
Rifles: Long-action bolt guns chambered in .338 Lapua Magnum that accept AICS-pattern magazines.
Not for Short Action: This is a long-action magazine. For .308, 6.5 Creedmoor, or other short-action cartridges, use the corresponding SA AICS magazines.
Feeding Variables: Action timing, feed-ramp geometry, and cartridge profile vary—test fully before match or hunt.
Real-World Benefits
Confidence on the Clock: Consistent round presentation supports smooth bolt work during pressured stages or windy engagements.
Stable in the Dirt: 5-round height keeps the rifle low on bags and bipods, improving stability and comfort in prone.
Built for the Elements: Protective finish and metal construction shrug off moisture, mud, dust, and travel abuse.
Easy to Service: Floorplate removal makes it simple to clear grit after a dusty day or a rain-soaked hunt.
Ideal Use Cases
ELR/Long-Range Matches: Reliable .338 LM feeding when every point—and every second—matters.
Big-Game & Mountain Hunts: A tough, low-profile mag for long shots and rugged environments.
Zeroing & Dope Work: Run longer strings without constant topping off while truing ballistic data.
Training & Practice: Durable enough for high round counts and repeated prone/barricade work.
Setup & Function Checklist
Confirm Pattern & Inlet: Ensure your chassis or bottom metal is AICS 3.85" long action.
Set COAL: Check your longest intended load (by bullet type/ogive) for internal clearance and smooth hand-cycling.
Hand-Cycle Safely: With the rifle unloaded, verify pickup and ejection from full and partial stacks.
Live-Fire Validation: Confirm function at match speed from prone and field positions.
Witness Marking: Note feed-lip settings or floorplate orientation after any tuning/cleaning.
Care & Maintenance
Field Strip: Remove floorplate, spring, and follower to wipe out dust, sand, and moisture.
Minimal Lube: Avoid heavy oils that trap grit; a dry film or very light protectant is sufficient.
Inspect Feed Lips: After impacts or drops, check for bends; dress carefully if needed.
Spring Health: Replace if you notice sluggish feeding or inconsistent last-round pickup.
