MDT AICS Style 10 Shot Black

The MDT AICS Style Shot magazine in black polymer is a 10 round detachable box magazine built for MDT chassis systems and, just as importantly, for the many other M24 type chassis and bottom metals in circulation. If you are running a precision bolt gun in a chassis, this is the pattern your rifle was almost certainly designed around.

AICS is the pattern that became the industry standard for detachable magazine bolt rifles. Standardizing on it means your magazines, bottom metal, and chassis all speak the same language.

What the MDT AICS Style Shot Magazine Fits

These external box magazines are designed to fit the MDT TAC21, ACC, ESS, LSS-XL, XRS, and LSS chassis systems, as well as many other M24 type chassis and bottom metals. That breadth of compatibility is the main reason a shooter buys into the AICS pattern in the first place, since it keeps the aftermarket wide open.

Precision rifle competitors, long-range hunters, and anyone who has converted a bolt gun from a hinged floorplate to a detachable magazine setup are the intended users. Ten rounds is the practical capacity for a match stage or a day in the field, and having several loaded magazines beats topping off through the ejection port between strings every time.

Key Features

• 10 round capacity in a detachable external box magazine
• Manufactured from high quality polymer with a high glass content for strength
• Tempered steel spring for consistent feeding pressure
• Fits MDT TAC21, ACC, ESS, LSS-XL, XRS, and LSS chassis systems
• Also works in many other M24 type chassis and bottom metals
• Black finish that matches most chassis and stock systems

Materials, Testing, and Specifications

Polymer with a high glass content is a meaningful specification rather than marketing language. Glass fill dramatically increases the stiffness and strength of a polymer part, which is what allows a magazine body to resist flexing under spring pressure and impact. Flex is what causes feeding problems, so rigidity in the body translates directly into reliability at the top.

MDT puts its magazines through vigorous testing, including driving over them with cars and trucks without breaking them. That is not a claim of being unbreakable, and the company is careful to say so, but it does tell you where the design sits on the durability scale. The tempered steel spring inside the MDT AICS Style Shot magazine is what maintains consistent feeding pressure through the full stack.

Practical Use, Care, and Compatibility

Confirm your chassis or bottom metal accepts AICS pattern magazines before ordering, and check the length your cartridge requires, since long-action and short-action bodies are not interchangeable. Most M24 type systems will accept these directly, but there is enough variation in aftermarket bottom metal that a quick check saves a return.

Load magazines the day before a match rather than at the line, and seat rounds fully to the rear of the body so they present cleanly to the feed ramp. Number the baseplates so you can track which magazine was in the rifle if you encounter a feeding issue during a stage.

Clean the interior with a dry cloth after dusty conditions and avoid oiling the inside, since oil attracts the grit that causes problems. Inspect the feed lips after a hard drop.

One practical note for match shooters: build a rotation. Keep four or five MDT AICS Style Shot magazines in service, label them, and cycle through them across a season so wear is even and any developing problem shows up in practice rather than on the clock. Retire a body that has taken a hard hit rather than trusting it, since a magazine is the cheapest component in a precision rifle and the easiest one to replace.
