October Mountain Crossbow String 34.5 In. Killer Instinct Rush 380

The October Mountain Crossbow String 34.5 In. Killer Instinct Rush 380 is a precision replacement string engineered for hunters who demand reliability in the field. Built to exact specifications for the Killer Instinct Rush 380 platform, this string restores factory performance and consistency shot after shot. Whether you're maintaining a well-used crossbow or upgrading to premium materials, a quality string is as critical to your accuracy as a sharp broadhead—it's the direct link between your bow's energy and your target.

Constructed from October Mountain's proven Velocity Plus material, this 34.5-inch string combines durability with consistent velocity retention across seasons. The tight nylon center serving protects the string's core from abrasion and fraying, extending service life in harsh weather and repeated use. End loops are precision-engineered to fit securely in your crossbow's limb pockets, eliminating play and ensuring zero creep between shots—critical factors that separate accurate groups from scattered impacts downrange.

Crossbow hunters who log dozens of practice sessions and multiple seasons in the field understand that string condition directly affects velocity and accuracy. This replacement string is ideal for maintenance-conscious shooters refreshing aging strings or those transitioning to a Killer Instinct Rush 380 platform. Installation is straightforward on compatible Killer Instinct models; proper nocking and string alignment take minutes and require no special tools. Regular string inspection and timely replacement—typically every 2–3 years of active hunting—keeps your crossbow performing at peak efficiency.
