A version of the AR-15 named the "Centurion-15" was produced by Century International Arms in 1996, and 1997. The lower receivers uses on the rifles were manufactured by Olympic Arms under contract for CIA. However, the only parts used for the manufacture of these rifles that were actually manufactured by Olympic Arms are the receivers themselves, and the safety selectors (which in this case happen to be reversible).

There is often much confusion over these weapons, as to whom is responsible for there proper function, as well as product liability. In every case, regardless of question, all responsibilities with regards to product liability is the sole responsibility of Century International Arms.
