It was hard to find in September 2026, in stock on only 11 of the 21 days we checked, and today both retailers we track have it in stock. Prices barely moved in September 2026, holding around $174, so there haven't been real sales lately. Buying today, the lowest price is $174 at AR15 Discounts, which matches the best price we saw in September.
