Another cause of bad introduction is incomplete feeding due to lack of power. In this case screw up the regulator 3 to 10 divisions.
(4) Incomplete ejection of the spent cartridge case.
This is due to lack of power. Screw up the regulator 5 to 10 divisions.
CLEANING AND CARE.
This arm requires the same care as the service rifle. It must be kept clean and free from rust, and all parts lightly oiled. No gritty substances or emery should be used.
As soon after firing as practicable the barrel should be thoroughly cleaned and oiled, particular attention being paid to the chamber.
The gas cylinder should be kept free from fouling by means of the cleaner so that the regulator can be easily screwed up without using the dismounting wrench.
When the gun is not in use the breech should be kept closed so as to avoid weakening the recoil spring.
FEED STRIPS.
The feed strips hold 30 rounds each. There are three rows of clips which hold the cartridge near the base, the middle and at the neck. A stop lug which catches behind the head of the cartridge case prevents longitudinal motion.
