LateralWorks C-4 Bag Rider — for KRG C-4 Chassis

Precision-printed PET-CF replacement bag rider engineered to correct the ergonomics and adjustability shortfalls of KRG’s stock unit.

Overview

The stock bag rider on the KRG C-4 chassis limits how the rifle sits in the bag and how easily you can fine-tune your rear support — cramped adjustment access, awkward hand positioning when making changes on the clock, and a footprint that doesn’t track consistently across bag types. The LateralWorks C-4 Bag Rider is a direct-fit redesign that solves these problems while retaining full compatibility with the KRG C-4’s existing mounting hardware.

Key Improvements Over Stock

• Reworked ergonomics — adjustment points are relocated and reshaped for faster, more intuitive hand contact, so you can make rear-bag adjustments without breaking your position or fumbling for the right surface.
• Improved adjustment travel/access — geometry opens up clearance around the fasteners so tuning doesn’t require tools or awkward wrist angles mid-string.
• Consistent bag tracking — wider, more predictable footprint gives a more stable interface across rabbit-ear and squeeze bags alike.
• Drop-in compatibility — bolts directly to the KRG C-4 chassis using the factory mounting pattern and hardware; no chassis modification required.

Material & Construction

• Printed in PET-CF (carbon-fiber-reinforced PET) for a stiff, low-moisture-sensitivity part that holds dimensional accuracy under field conditions — chosen specifically over standard PETG or nylon-based composites for its stability in humid/wet environments and resistance to creep under clamping load.
• Precision FDM-printed to close tolerance for a consistent, repeatable mount every time.
• Matte black finish to match the C-4’s factory hardware and coatings.

Compatibility

• KRG C-4 Chassis (all variants using the standard bag rider mounting interface)
