All Daniel Defense cold hammer forged barrels are manufactured start to finish in their state of the art facility in Black Creek, Georgia. The cold hammer forging process allows the barrel's rifling and chamber to be formed as the barrel is shaped, creating a defect free bore and the most consistent and concentric chamber possible. Starting with the best possible materials and ending with the best possible finishes, these barrels will prove to be more accurate and longer lasting than traditionally cut or button rifled competitors.
