The Wilson Combat 647 is a stainless drop-in match-grade barrel built for the Glock 19 9mm platform. Machined from 416R Stainless Steel and R/C 40 heat treated for durability, this barrel holds manufacturing tolerances within .0005″. The 1:16 twist broach rifling delivers pinpoint accuracy of 2″ or less at 25 yards when loaded with quality ammunition.
This Wilson Combat barrel fits generation 3, 4, and 5 Glock 19 handguns as a direct drop-in upgrade. The 1 in 16″ twist conventional broach rifling accommodates lead, jacketed, or plated bullets without the pressure spike concerns associated with polygonal rifling. The chamber has been precision finished to a glass-smooth surface and machined concentric to the bore.
Every barrel receives multiple quality-control checks throughout manufacturing, followed by detailed final inspection before it carries the Wilson name. Whether you’re upgrading your carry gun or enhancing a target shooter, this match-grade barrel delivers the precision and durability Wilson Combat is known for.
