Maydaysan Airsoft says that upgrade parts for the Krytac KRISS Vector AEG from Laylax can bring its performance to another level... "The Kyrtac Airsoft Vector is a good airsoft replica out of the box but it does leave a lot to be desired. Luckily there are some great Laylax parts that help make this airsoft vector one of the best tools to bring onto the airsoft field."
