LaChassis is the foundation of Grey Birch, the company, the solid ground on which we will build our house. The end goal in building LaChassis has always been a lightweight, modular, adjustable and secure base to firmly house the barreled action in place from two locations. Everything builds off a firm foundation.

LaChassis is a modular chassis system built around the 10/22® platform and is packed with features to enhance the shooting experience with configurations ranging from short range race gun to long range precision.
