It was hard to find in October 2026, in stock on only 12 of the 23 days we checked, and today only Optics Planet has it in stock. It dipped to $213.75 at BattleHawk Armory for a stretch in October 2026, well under its usual $246.95, so sales do come around. Buying today, the lowest price is $246.95 at Optics Planet, above October's low of $213.75, so a better deal may come back.
