ZC Leopard 6.02mm VSR/GBB Tightbore Steel Barrel; 240mm

If you want to squeeze more performance out of your replica, upgrading to a tightbore inner barrel is one of the most effective options available. This stainless steel tightbore from ZC Leopard improves air efficiency, typically resulting in a modest FPS gain, and delivers more consistent accuracy at range thanks to its reduced bore diameter and high-quality internal finish. Designed to fit standard GBB and VSR platforms, this 240mm inner barrel is ideal for compact builds. The stainless steel construction offers far greater rigidity than traditional brass barrels, ensuring it won’t flex even during sustained rapid fire. Combined with its smooth, precision-polished interior, this barrel helps maintain stable BB flight and reliable shot-to-shot consistency.
