MDT AICS Magazine – 5-Round Extended, .300 PRC, Long Action Magnum (CIP 3.80"), Black Steel (105123BLK)

Model/SKU: 105123BLK • UPC: 682157400010
Caliber: .300 PRC • Capacity: 5 Rounds (Extended) • Pattern/Length: AICS Long Action – CIP 3.80" • Material/Finish: Steel, low-glare black corrosion-resistant coating • Color: Black

Unlock the full potential of modern magnum ballistics with the MDT 5-Round Extended AICS Magazine for .300 PRC. Purpose-built around the CIP 3.80" long-action spec, this steel magazine supports the longer overall lengths common to heavy, high-BC bullets—so you can load for precision without being boxed in by short inlets. The extended body improves stack geometry and cartridge presentation, while MDT’s proven feed-lip profile, anti-tilt follower, and high-tension spring deliver repeatable, nose-up feeding in punishing field and match conditions.

Why This MDT .300 PRC CIP Magazine Stands Out

• True CIP 3.80" length: Designed for AICS-pattern long actions cut to 3.80"/3.850" CIP magazine wells—ideal for long, heavy .30-cal bullets and optimal seating depth.

• Feed reliability you can trust: Tuned feed lips and a self-centering follower promote smooth chambering across diverse ogives (ELD-M/ELD-X, OTM, mono solids).

• Rugged steel construction: Stamped and heat-treated steel body with a durable black protective finish resists dents, abrasion, and corrosion.

• Extended 5-round design: Compact enough for prone and tripod work, yet generous for hunting, training, and most match stages.

• Service-friendly floorplate: Removable floorplate simplifies cleaning after dusty, wet, or high-round-count days.

Fitment Note: This magazine is for CIP-length (3.80"/3.850") long-action AICS inlets and bottom metals. It will not fit standard 3.715" long-action cuts. Verify your chassis/stock inlet before purchase.

Performance Advantages

• Load long, shoot long: Supports longer COAL for seating near the lands or maximizing case capacity with heavy projectiles.

• Consistent presentation: Extended body and tuned geometry reduce nose-dive, stack chatter, and tip damage under recoil.

• Built for real weather: Steel shell and protective finish thrive in rain, mud, snow, and backcountry abuse.

Ideal Use Cases

• Long-range hunting: Elk, moose, and mountain hunts where reliability and long-OAL bullets matter.

• Precision/ELR: Repeatable feeding for high-BC bullets at distance—great for dope validation and training.

• Duty/LE training: Durable, drop-resistant mag for vehicle and field environments.

Best Practices & Care

1. Confirm inlet length (CIP 3.80"/3.850") on your action/chassis.

2. Disassemble via the floorplate; brush out grit and moisture after harsh conditions.

3. Lightly oil the spring for corrosion control; keep follower and interior walls mostly dry.

4. Function-check and verify lock-in/bolt-over speed with your chosen loads before match day or a hunt.
