Extended Optics Shroud for Modern Setups
The extended optics shroud on the C4X-R7S-XTO is one of its most valuable features. This extended shroud provides additional clearance and protection for large objective lenses, high-mounted scopes, and night vision devices. Many modern precision builds require extra space above the action for optics and accessories. The extended shroud on this chassis accommodates these setups while maintaining a clean, integrated appearance and protecting sensitive components from debris and impact.
Ergonomic Vertical Thumbgrip
The vertical thumbgrip featured on the C4X-R7S-XTO offers a more natural and secure hand position compared to traditional horizontal shelves. This design allows shooters to maintain consistent grip pressure and better trigger finger placement, which can lead to improved accuracy and reduced shooter fatigue. The thumbgrip is especially beneficial for prone shooting and long-range precision work where maintaining a stable and repeatable position is critical for consistent performance.
Comfortable Overmolded Grip Panels
The overmolded grip panels on the C4X-R7S-XTO provide a secure and comfortable hold in a wide range of conditions. These panels are designed to perform well in wet, cold, or hot environments, offering excellent traction without being overly aggressive. The overmold material enhances shooter comfort during long days at the range while still maintaining positive control during rapid follow-up shots or in dynamic shooting situations.

Free-Floating Forend for Maximum Accuracy
Like all KRG C-4 chassis models, the C4X-R7S-XTO features a free-floating forend that prevents any contact with the barrel.
