Designed for Precision. Built for the MRX Bison.

The MRX MAG is a proprietary 20-round polymer magazine specifically engineered for the Black Creek Labs MRX Bison and MRX Jackal bolt-action rifles in 5.56 NATO and .300 Blackout. Unlike standard AR-15 magazines, this double-stack, straight-body magazine ensures ultra-smooth and reliable feeding, while its high-strength polymer construction provides durability in any condition.

Key Features:

• Optimized for the MRX Bison & MRX Jackal – Will not fit or function in AR-15 or other semi-auto rifles.
• Proprietary Polymer Construction – Engineered for toughness, durability, and impact resistance.
• High-Strength Stainless Steel Spring – Ensures consistent feeding and longevity.
• No-Tilt Follower with Stop Ledges – Prevents the follower from topping out, allowing the bolt to close on an empty magazine (unlike AR-15 mags).
• Straight Design for Smooth Feeding – Reduces bullet binding for improved reliability.

• Capacity: 20 rounds
• Material: High-strength polymer
