Ballistic Advantage Premium Series Barrel Features The Ballistic Advantage Premium Series barrel is machined from hardened 416R stainless steel and finished with QPQ followed by a gold PVD coating a combination that improves surface hardness and wear resistance while adding a durable corrosion fighting layer. The spiral fluted profile cuts unnecessary weight from the barrel without sacrificing rigidity helping keep the pistol balanced and quick to control. A 1:10 inch button rifled twist rate is cut for consistent accuracy shot after shot in 9mm Luger. At 3.2 oz this drop in barrel adds negligible extra weight to a Glock 17 Gen5 build. Threaded 1/2x28 at the muzzle the barrel allows straightforward attachment of a suppressor or compensator for shooters looking to expand their pistol s capability. A standard thread protector is included to keep the threads protected and the muzzle looking clean when a device is not mounted. This barrel is designed as a direct fit replacement for the Glock 17 Gen5 giving owners an upgrade path for improved finish and features over a stock barrel. Ballistic Advantage backs the Premium Series with the same attention to tolerance and finish quality found across their broader barrel lineup.
