This is the MDT 10 round steel .223 magazine for rifles using the AICS short action format.
Based on MDT's heat treated .308 magazine body the magazine features a polymer insert for the .223 round stack and is finished in Ceracote Elite.
Due to MDT's shorter funnel on their Double Stack Single Feed (DSSF) design MDT magazines are approx 3/4" shorter in height than other AICS 10 round types.
Max OAL = 2.5" / 63.5mm
