One of the main drawbacks for buying a Promaster is that it does not come stock with an ASA, which means that the owner will have to add one before he or she uses the marker.Many users have reported a "break-in" period before the marker performs consistently, as is common in most markers.The Promaster does not come stock with a clamping feedneck, a device that locks onto a hopper and keeps it more secure than a standard feedneck.
