For those customers who want the lighter weight and adjustable bag rider for their Matrix Chassis, we are now offering the Matrix Pro Buttstock.
The stock is 6 oz. lighter.
This will fit any MPA Matrix Chassis. (Sorry, it wont fit any other MPA Chassis).
Just remove the grip, remove the Flat Head Cap Screw from the top of the chassis, the Socket Head Cap Screw from the bottom, and remove your current Matrix Buttstock. Install the new one by reversing these directions.
