The Kinetic Research Group Tool-Less Length-Of-Pull Kit For Gen4 X-Ray Chassis gives X-Ray Gen 4 and Gen 5 owners fast, precise stock fit adjustment without reaching for tools or swapping spacers. Built around a robust polymer adjustment plate and hardware, this kit integrates cleanly into the buttstock to provide smooth, repeatable length-of-pull changes while preserving a solid, stable shooting platform.

Designed specifically for the X-Ray Chassis system, this kit is ideal for shooters who share rifles, transition between shooting positions, or fine-tune their fit for consistent cheek weld and recoil control. The thumbscrew can be configured on either side for user preference, and the system maintains the factory tool-less buttpad height and cant adjustments found on X-Ray Gen 4 and Gen 5 stocks. It’s a practical upgrade that reflects Kinetic Research Group’s focus on thoughtful ergonomics and shooter-friendly innovation.
