It was hard to find in August 2026, in stock on only 3 of the 12 days we checked, and today the one retailer we track has it in stock. Prices barely moved in August 2026, holding around $49.95, so there haven't been real sales lately. Buying today, the lowest price is $49.95 at Primary Arms, which matches the best price we saw in August.
