The redesigned system operates the same, but modifies and simplifies some components, including a new buffer and recuperator with a majority of the components removed, and adds the Suspension Lockout System ( SLOS ) that fixes recoil length at, which removes variable-recoil hardware, reduces stress on the carriage, and lowers buffer rod forces; the new system reduces cost, number of parts by 40 percent to 75, and overall weight by.
