  1. Great mag
    I actually got these for a 50 Beowulf build (12.7x42mm) and although they hold only 4 rounds of the larger cartridge they work great.

These mags are engineered with the highest levels of quality, simply the best in the industry. Heat-treated stainless steel for superior strength and endurance. Chemically treated for corrosion resistance [ref QQ-P-35] and coated with ASC's proprietary finish Marlube which is a wear-in not wear-off coating that burnishes into the surface that self-lubricates. The interior dimensions of OAL 2.316” ± .002 are perfect for reloads.
