The MDT AICS Magazine 105123BLK delivers extended cartridge compatibility for 300 PRC chambered rifles with its CIP 3.80" length specification. This 5-round magazine accommodates longer magnum cartridges that exceed standard AICS magazine dimensions, enabling optimal performance with high-BC projectiles and extended-length handloads.
What Makes This Different
Standard AICS magazines limit cartridge overall length to approximately 3.56", restricting bullet selection and seating depth optimization. The extended CIP 3.80" internal length provides an additional 0.24" of cartridge space, allowing shooters to seat heavy-for-caliber bullets at optimal depths without magazine interference. This translates to improved ballistic coefficients and enhanced long-range performance compared to compressed loads required by shorter magazines.
Key Features
- CIP 3.80" internal length accommodates extended 300 PRC cartridges
- 5-round capacity balances ammunition supply with weight considerations
- Black steel construction provides corrosion resistance and durability
- Standard AICS pattern fits Remington 700, Savage 110, and compatible actions
- Long action magnum configuration for belted and non-belted cartridges
- Precision-engineered follower ensures reliable feeding geometry
- Heat-treated steel construction withstands repeated cycling
Field testing demonstrates consistent feeding with factory 300 PRC ammunition and handloads utilizing bullets up to 230 grains. The extended magazine body prevents cartridge compression that can affect powder charge consistency and accuracy. Competition shooters benefit from the ability to load cartridges to maximum SAAMI specifications without magazine length restrictions.
