Why choose the MDT 3-Round .300 Win Mag AICS magazine
AICS-Pattern Confidence
Built to Accuracy International Chassis System (AICS) dimensions for broad compatibility with premium chassis and DBM systems (MDT, KRG, XLR, MPA, and more).
Magnum-Ready Feeding
Internal geometry is tuned for .300 Win Mag—supporting reliable pick-up, controlled presentation, and positive chambering with popular hunting and precision bullets.
Low-Profile, Field-Smart Capacity
A 3-round configuration keeps the rifle compact for prone shooting, barricades, and mountain hunts where clearance and weight matter.
Lightweight Polymer Construction
The rugged polymer body resists dents and dings, helps maintain feed-lip integrity, and stays quiet in cold conditions compared to thin stamped steel.
Weather-Resistant & Serviceable
Corrosion-proof materials and a user-friendly design make cleaning simple after wet hunts or dusty range days.
Ideal applications
Backcountry Hunting: Minimal bulk in the pocket or pack, with magnum reliability for big game.
Precision/Long-Range: Low-profile mag avoids interfering with bags and tripods during prone strings.
Range & Zeroing: Smooth, repeatable feeding helps confirm dope without mag-induced flyers.
Compatibility & fit notes
Intended for: AICS-pattern long-action in 3.850" configuration.
Chassis/Bottom Metals: Works with many AICS long-action systems; always confirm inlet and magwell specs for 3.850" pattern.
Cartridge Overall Length (COAL): Verify your seated bullet length against internal magazine clearance—especially with long-ogive, high-BC projectiles.
Not for Short/Medium Actions: Designed specifically for long action (3.850"). Use the correct MDT magazine for other action lengths/calibers.

Pro tips for best performance
Seat to the rear: When loading, press rounds firmly to the rear to keep the stack uniform for optimal pickup angle.
COAL check: Long, heavy-for-caliber bullets can approach internal limits—verify and function test.
Torque matters: Correct bottom-metal torque helps ensure ideal mag latch height and feed path.
Keep it clean: Periodically clean the interior and follower; a light dry lube can help in very dusty environments.
Cycle dummies: Before the hunt, verify feeding with inert rounds across different positions (prone, kneeling, uphill/downhill).
Frequently asked questions
Q: Will this fit any .300 Win Mag long-action chassis?
A: It’s designed for AICS-pattern long actions (3.850"). Most AICS-compatible chassis and DBM units will accept it; confirm your specific system’s magwell dimensions.
Q: Is polymer as durable as steel?
A: The impact-resistant polymer resists dents and is quiet in the cold. It also preserves feed-lip geometry well for consistent reliability.
Q: Can I run extra-long COAL handloads?
A: Check your load’s COAL against the mag’s internal length. For very long bullets seated out, single-feeding or a different magazine format may be required.
Q: Does it work with other long-action magnum cartridges?
A: This model is tuned for .300 Win Mag. MDT offers other mags for different cartridges—use caliber-specific models for best results.
