MDT 338 Lapua Mag Metal Long Action Magazine (5 Round)
MDT 338 Lapua Mag Metal Long Action Magazine (5 Round) is a 5-round steel magazine for 338 Lapua Magnum long-action rifles, finished in Cerakote Elite for durability and corrosion resistance. The 5-round capacity is based on magnum cartridges.
Long-action magazine wells come in different lengths, so MDT makes this magazine in 3.715″ and 3.850″ CIP versions: the 3.715″ magazine takes cartridges up to 3.600″ overall and the 3.850″ CIP magazine takes cartridges up to 3.740″ overall. The 3.715″ length is the standard long action in MDT chassis. The 3.850″ CIP version is for CIP-length chassis and bottom metals that allow longer magnum loads.
Check which magazine length your chassis or bottom metal takes before ordering. If you bought a complete rifle from a factory or retailer, check its specification: Remington Tactical Chassis rifles and 338 Lapua XCR rifles use a 3.775″ magazine, which MDT does not make.
