Brownells 75th Anniversary - A Shooting Heritage

The LaChassis 10/22 is the next evolution of 10/22™ compatible chassis from Grey Birch Solutions. The end goal in building LaChassis 10/22 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.

The LaChassis 10/22 is a modular chassis system built around the 10/22® platform. LaChassis 10/22 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 the LaChassis 10/22 is its rear tension point, adding a second location to hold your barreled action in place for precise shooting.
