This is the MDT AICS Short Action 10-round magazine in .223 Remington and 5.56x45mm NATO. Does not come with a binder plate.

This AICS-pattern magazine features a high-strength, nitride steel body for maximum durability. Plus, it has been finished inside and out with Cerakote Elite for corrosion resistance and friction reduction.  

Specifications

• 3.055” Outside Length
• 3.90″ Rear Height (same height as MDT 10-rd .308 metal magazines)
• 2.50” max cartridge overall length (COAL)
• Polymer feedlip inserts extend ~0.5″ past the end of the metal feedlip backer, thus retaining the round longer, helping ensure the tip of the round has entered the chamber before the rear of the round is released.

MDT 10-round magazines are approximately ¾” shorter in height than standard AICS 10-round magazines due to MDT’s unique Double Stack to Single Feed (DSSF) transition design, allowing easier mag changes when shooting prone.

10-round magazine includes 2 internal ribs that help reduce friction between the cartridge and magazine body and provide a smooth transition from a double stack to single feed at the top of the magazine.
