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. One of the key features of LaChassis is its rear tension point, adding a second location to hold your barreled action in place for precise shooting.
