79

What are the two most common types of malfunctions?

Sluggish operation and runaway gun

80

Sluggish Operation

Gun fires very slowly. It can be due to excessive friction or loss of gas. Excessive friction is usually due to lack of lube or excessive dirt/carbon. Move the regulator setting to two or three. Clean, inspect and lube the gun

81

Runaway Gun

Gun continues to fire after trigger is released; caused by worn, broken or burred sear or worn sear notch. Point weapon down range. Let the weapon fire off remaining rounds if near end. Team leader should break off belt it not.

82

Stoppages

Interruption in the cycle of operation caused by faulty gun or ammo

83

Hang Fire

Cartridge primer has detonated after being struck by the firing but some problem with the propellant powder causes it to burn too slowly and delays the firing projectile

84

Cook Off

Occurs when the heat of the barrel is high enough to cause the propellant powder inside the round to ignite even though the primer has not been struck

85

Stuck Cartridge

If swelling is excessive the cartage will be fixed tightly in the chamber. If extractor spring has weakened and does not tightly grip the base of the cartridge, it may fail to extract a round when the bolt locks to the rear.
