This MDT metal magazine handles the demands of .300 Winchester Magnum rifles without compromise. Built from high-strength steel and given a nitride finish before being coated with Cerakote Elite, you're getting a magazine that can take real abuse. Whether you're working with a precision chassis system or a custom bolt gun, this magazine pairs reliability with durability.
The 3.715-inch length is the standard fit for most MDT chassis systems and AICS-pattern magazine wells. It's specifically engineered for magnum rounds, holding five cartridges designed for .300 Win Mag. The Double Stack to Single Feed transition keeps the overall height manageable while feeding rounds smoothly, backed by a precision-machined feed lip design that grips rounds securely.
This magazine uses a nitride-finished steel body with Cerakote Elite applied to both inside and outside surfaces. That combination means you get friction reduction along with corrosion resistance. The steel spring and polymer follower work together to provide the kind of feeding consistency you need at the range or in the field. A removable floor plate makes cleaning and maintenance straightforward when you need it.
This magazine is designed to fit standard AICS-pattern detachable box magazine systems and compatible bottom metals. If your rifle has a 3.715-inch magazine well, this will work. That covers most modern MDT chassis builds and many custom rifles built on standard AICS platforms. The magazine can also handle 7mm Rem Mag, 30-06, and 6.5×55 with minor feed lip adjustments if needed.
Yes, if your MDT chassis has a standard 3.715-inch magazine well. This is the most common length for MDT long-action systems. If you have a Tikka T3/T3x or Savage Axis platform, you'll need the shorter 3.560-inch version instead. Check your rifle's specifications to confirm which length you need.
The magazine can handle 7mm Rem Mag, 30-06, and 6.5×55 with minor adjustments to the feed lips. The maximum cartridge overall length is 3.615 inches for this 3.715-inch magazine. It won't work with 300 Remington Ultra Mag or 300 Weatherby Magnum.
Cerakote Elite is applied over a nitride-finished steel body, which means you get friction reduction along with superior corrosion resistance. This combination protects the magazine inside and out, so it holds up in harsh conditions without binding or feeding issues.
The removable floor plate makes disassembly quick and easy. You can pop out the spring and follower to clean the inside. Wipe down the exterior with a cloth, and occasional light oil keeps everything moving smoothly. Because of the Cerakote finish, it doesn't require the frequent attention that bare steel would.
