The Hawkins Precision Hunter Long Action 300 NM/338 Lapua Flush Mount Magazine is a precision-machined detachable magazine engineered for long-action magnum hunting rifles that use Hawkins Precision Hunter DBM bottom metal systems. Built from a single billet of aluminum with a corrosion-resistant finish, this magazine provides a flush-fit design that reduces snagging while still allowing extended cartridge overall lengths up to approximately 3.770in — perfect for long magnum rounds like .300 Norma Magnum and .338 Lapua. The magazine holds 3 rounds and is optimized for reliable feeding in hunting and precision shooting applications when paired with compatible bottom metal.
