The Azodin KPC+ is a fantastic pump marker that is affordable, easy to use, and comes stock with an auto trigger! The big advantage to using a pump with auto trigger is that you can hold the trigger down, and once you pump the marker it will fire, as opposed to traditional pump markers that you need to pump then pull the trigger. This helps to not be too out gunned when playing against people with faster markers. The KPC + also comes stock with an on / off ASA, Clamping Feedneck, a slim comfortable pump handle, and an adjustable regulator! These markers use Autococker threaded barrels, so it is easy to find upgrade options for them!
