Build history on GunPartPicker
Builders on GunPartPicker first added the FN America Auto Sear Assembly to a build in May 2026.
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 $152.89, so there haven't been real sales lately. Buying today, the lowest price is $152.89 at Primary Arms, which matches the best price we saw in September.
