The BKO series marker was released to the public in 2002. The BKO was designed to be a cheaper alternative to the B2K, but still able to keep up with the day's high-end guns. Rumor has it that the BKO got it's name from the code name durring it's production. BKO, or in other words, Bushmaster Knock Off.
Same as with the Bushmaster, the BKO production line has been shut down since 2004.
