Frequently Asked Questions

Why does a magnum-caliber magazine only hold 5 rounds?

Magnum cartridges like .300 Win Mag are longer, so the AICS-pattern magazine body holds fewer rounds than standard-length calibers.

What finish does this magazine use?

Cerakote Elite over high-strength steel, for durability and corrosion resistance.
