Builders have been adding it to their builds on GunPartPicker since February 2026. All time, it ranks #102 of the 1,001 lower receivers builders have added.

Availability is good: it was in stock at one retailer or another nearly every day in August 2026, and today 5 of the 9 retailers we track have it in stock. Prices barely moved in August 2026, holding around $514.95, so there haven't been real sales lately.
