Description
This is a genuinely specialized magazine for the 300 PRC shooter who doesn't need full capacity. The 3-round design cuts weight and eliminates bulk while maintaining the strength and reliability you expect from MDT. If you're building a precision rig that's already dialed in for long-range use, this magazine pairs perfectly with that application.
Machined to CIP Specifications
The magazine comes in at 3.850 inches overall length, machined to CIP spec for the 300 PRC cartridge. This means proper headspacing and feeding of your long-range rounds without compromise. The CIP designation also means it'll work with any CIP-length chassis or bottom metal, so compatibility isn't a guessing game.
Built for Durability Without Extra Weight
Manufactured from high-strength steel and finished with Cerakote Elite, this magazine handles real-world use. The finish resists corrosion and reduces friction inside the action, so it keeps cycling smooth whether you're in wet conditions or dusty terrain. The metal construction means no compromises on strength for the sake of the reduced capacity. At 3-rounds, you also get a weight savings compared to higher-capacity options without sacrificing the durability needed for precision hunting and competition.
Designed for Minimalist Setups
Three rounds keeps the magazine profile low when loaded, reducing snag points and unnecessary bulk. This matters in brush, moving through rough terrain, or any time you want a rifle that sits clean in your chassis. It's built for the hunter or competitor who runs dialed-in handloads and doesn't need to carry spare capacity.
