Long action rifles in a chassis need magazines too, and this MDT polymer AICS magazine covers the 30-06 Springfield class of cartridges. The 3rd capacity keeps the magazine body compact and the rifle's belly clean, which suits a hunting rig that rides in a scabbard or across a pack.The AICS long action footprint fits MDT chassis and compatible bottom metal, and the polymer body keeps weight off a rifle that already carries a long barrel and a full size scope. Three in the magazine plus careful shooting has settled plenty of tags over the years.
