September 2026 on GunPartPicker
FailZero 6mm ARC Bolt Carrier Group Steel ranked #67 of the 217 bolt carrier groups builders added on GunPartPicker in September 2026. Builders have been adding it to their builds on GunPartPicker since May 2026. All time, it ranks #143 of the 452 bolt carrier groups builders have added.
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. Prices barely moved in September 2026, holding around $144.51, so there haven't been real sales lately.
