UZI 9MM 16.25" OAL QPQ Nitride Barrel

This 16.25" Uzi Barrel is precision-machined from 4150 chrome moly steel and features a superior QPQ nitride finish for maximum durability and corrosion resistance. Chambered specifically for 9mm semi-auto Uzi rifles, this barrel features a 1:10 twist rate that ensures reliable feeding and optimal accuracy. The QPQ (Quench-Polish-Quench) nitride treatment penetrates deep into the steel, providing exceptional wear resistance, superior corrosion protection (exceeding chrome plating), and a durable matte black finish that requires no additional coating. The process increases surface hardness up to 70 HRC while reducing friction by up to 60%, resulting in smoother cycling and extended barrel life. Made in the USA.
