Availability is good: it was in stock at one retailer or another nearly every day in August 2026, and today the one retailer we track has it in stock. Prices barely moved in August 2026, holding around $175, so there haven't been real sales lately. Buying today, the lowest price is $175 at Primary Arms, which matches the best price we saw in August.
