Availability is good: it was in stock at one retailer or another nearly every day in September 2026, and today both retailers we track have it in stock. The best price crept up from $45.95 to $55.05 over September 2026. Buying today, the lowest price is $55.05 at AR15 Discounts, above September's low of $45.95, so a better deal may come back.
