MDT AICS Magazine 3-Round 6.5 PRC / 300 WSM Short Action Magnum – Black Steel (103133BLK)

Upgrade your precision rifle setup with the MDT AICS Magazine (103133BLK), a 3-round, short-action magnum magazine engineered for shooters who demand reliability and durability. Compatible with 6.5 PRC, 270 WSM, 7 RSAUM, and 300 WSM chamberings, this magazine is purpose-built for serious hunting and long-range shooting applications.

MDT’s innovative Double Stack to Single Feed (DSSF) transition design reduces overall magazine height compared to industry-standard options, keeping your chassis or stock profile sleek and low. Constructed from high-strength steel, each magazine is nitrided and finished inside and out with Cerakote Elite coating, delivering exceptional corrosion resistance, reduced friction, and long-term durability in the field or on the range.

Compatible with all AICS-pattern bottom metal and chassis systems, and supports a maximum cartridge overall length of 2.960″ (on models without front binder plates). Note: Common actions such as the Remington 700 and Savage 10/11 may require minor receiver modifications — such as notching the bottom of the feed ramp — to ensure reliable feeding.

• 3-round capacity in Short Action Magnum
