MDT Gen2 · .223 Remington · AICS
A .223 magazine for short AICS slots – not for every .223 rifle
This polymer magazine is designed for short-action AICS magazine slots and feeds .223 Remington or 5.56 NATO in the DSSF pattern. The crucial point is therefore the magazine well of the system, not just the caliber.
Before buying: Confirm Short Action + AICS


Black-Raptor classification: Good choice for a cleanly defined .223/5.56 bolt-action or chassis setup with a short AICS well. Not a universal replacement magazine for all guns in the same caliber.
Fits well / fits rather not


Fits well if …
Your chassis or bottom metal explicitly states Short Action and AICS.
You use .223 Remington or 5.56 NATO in a weapon approved for it.
You are looking for a lightweight 10-round polymer magazine.
The planned overall cartridge length is within the manufacturer’s limit.



Fits rather not if …
Your gun uses a proprietary magazine well.
You select only by caliber without knowing the well.
You use a Ruger American in .204, .223, 5.56, or .300 AAC – this combination is explicitly excluded in the existing data set.
You would have to modify the magazine to make it fit.



What the design means in practice


DSSF feed Double Stacked Single Feed combines double-row cartridge storage with a central feed position. This is the design of this specific magazine, not an approval for other systems.


Polymer instead of metal Glass-fibre reinforced nylon häl
t das Magazin leicht und unempfindlich gegen Korrosion. Der Werkstoff ist kein Grund, Passformprobleme mit Kraft zu übergehen.


10 rounds Practical for training sessions and range use. For very compact hunting setups, a smaller magazine can be more comfortable.


C.O.A.L. limit MDT specifies a maximum of 2.480 inches. This is a compatibility limit for cartridge length, not a loading recommendation.


Limits and avoiding bad purchases

AICS alone is not enough: it must be the short AICS receiver. A long-action or other proprietary counterpart is not interchangeable.
.223 does not automatically mean compatible: magazine well and firearm approval remain separate checks.
Do not modify: if fit or function is unclear, do not file, bend, or force.

FAQ
Does the magazine fit every .223 bolt-action rifle? No. A confirmed Short-Action-AICS receiver is required. Is 5.56 NATO also listed? Yes, the existing MDT data set assigns both .223 Remington and 5.56 NATO. Firearm approval must still be confirmed separately. What does DSSF mean? Double Stacked Single Feed: double-row storage with central feed position. Which cartridge length is relevant? MDT specifies a maximum 2.480 inches C.O.A.L. Check this limit against your intended ammunition before purchase. Can I use it in a Ruger American? For Ruger American in .204, .223, 5.56, and .300 AAC, this combination is explicitly excluded in the existing data set.

Clear purchase decision
Suitable if your system has a Short-Action-AICS magwell and the cartridge length fits. Do not buy if only the caliber is known – the magazine well is the key compatibility question here.
