It was in stock most times we checked in October 2026, but today none of the 8 retailers we track has it in stock right now. It dipped to $65 at BattleHawk Armory for a stretch in October 2026, well under its usual $73.81, so sales do come around. Listed prices start at $58.99 at Sportsmans Outdoor Superstore for when it comes back.
