Product Description The Rival Arms Precision V1 Match Grade Drop-In Barrel is a performance upgrade for your Glock 17 Gen 5, designed to deliver custom-level accuracy with true drop-in installation. Built from high-quality stainless steel and precision polished, this barrel features a durable low-temperature vacuum Physical Vapor Deposition (PVD) coating to help resist wear in harsh use.
