Build history on GunPartPicker
Builders on GunPartPicker first added the Brownells BRN-4 BARRELS 5.56X45MM to a build in May 2026.
Availability is good: it was in stock at one retailer or another nearly every day in August 2026, and today the one retailer we track has it in stock. Prices barely moved in August 2026, holding around $179.99, so there haven't been real sales lately. Buying today, the lowest price is $179.99 at Brownells, which matches the best price we saw in August.
