GLOCK 21 Factory Threaded Barrel 16x1 LH
This is a factory GLOCK threaded barrel for use in the GLOCK 21 and GLOCK 21 SF. It can also be used to convert the 21C to shoot as a non-compensated.
This barrel will not work in the 30, 30S, 30SF, or 36 due to the difference in the locking blocks.
Thread protector included.
Shooting reloaded and lead ammunition in GLOCK barrels is NOT recommended!
