This is a complete upper assembly for a GLOCK 20. It includes all internal parts including a barrel and recoil spring assembly. Good for use on full-size 10mm/.45 ACP frames. Please note: This assembly DOES work on SF frames.
GLOCK factory slides and receivers are items we receive on an infrequent basis. As they are high demand items, frequent back-orders and significant wait times may occur. Upon arrival we dedicate these slides and receivers starting with the oldest order, working our way to the newest order placed. Wait times vary by demand and by the number of the items received.
