Build history on GunPartPicker
Builders on GunPartPicker first added the FN America FN15 16in Carbine Upper Receiver Assembly to a build in February 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 $809, so there haven't been real sales lately. Buying today, the lowest price is $809 at BattleHawk Armory, which matches the best price we saw in September.
