The SAR700-A1 Chassis Folder is a custom add-on to the SAR700-A1 Chassis System. Easily installed between the Chassis body and Magpul CTR Stock, this attachment allows the system to collapse by 8-1/4" for easy transport. Extremely handy for carrying via backpack.
This will also work with any chassis that accepts standard mil-spec M4-style receiver extensions.
