September 2026 on GunPartPicker
Expo Arms Buffer Retainer Spring ranked #33 of the 57 buffer springs builders added on GunPartPicker in September 2026. Builders have been adding it to their builds on GunPartPicker since June 2026. All time, it ranks #44 of the 101 buffer springs builders have added.
Availability is good: it was in stock at one retailer or another nearly every day in September 2026, and today the one retailer we track has it in stock. Prices barely moved in September 2026, holding around $0.99, so there haven't been real sales lately.
