Introduction

Malfunctions

Self-loading rifle, lesson 7 of 8: failure to fire, feed or extract

What the trainer says

Sooner or later, a rifle won't do what you expect. The unit standard names three malfunctions: failure to fire, failure to feed and failure to extract. You need to recognise each, know its likely causes, restore the rifle to safe working order, and know when to hand it to a gunsmith.

What to do

Whatever happens, these come first

  1. 1Muzzle stays safeDownrange, always
  2. 2Finger off the triggerStraight along the side
  3. 3Wait if it didn't fireAt least 30 seconds: it may be a hangfire
  4. 4Then follow your drillAs your trainer showed you for your model
What the trainer says

Before you think about the cause, do these. Keep the muzzle downrange. Take your finger off the trigger. If the rifle didn't fire when you pressed the trigger, wait at least 30 seconds with the muzzle in a safe direction before you open the action, because the cartridge may be a hangfire that fires late. Then clear the problem using the drill your trainer showed you for your model. Drills differ between rifles, so learn yours on the range.

Three malfunctions

The three malfunctions

MalfunctionWhat you noticeCommon causes
Failure to fireA click, no shotFaulty cartridge, round not fully chambered, weak firing pin strike
Failure to feedThe next round doesn't go into the chamberMagazine not seated, damaged magazine, dirt
Failure to extractThe empty case stays in the chamberDirty chamber, worn or damaged extractor, ammunition
What the trainer says

Here are the three. A failure to fire: you press the trigger and hear a click, but no shot. It could be a faulty cartridge, a round that isn't fully in the chamber, or a weak strike from the firing pin. A failure to feed: the next round doesn't make it into the chamber, often because the magazine isn't properly seated, or is damaged or dirty. A failure to extract: the empty case stays stuck in the chamber, which can be dirt, a worn or damaged extractor, or the ammunition. Think back to lesson 2's cycle: each malfunction is a step that didn't happen.

Three malfunctions

Where each one breaks the cycle

  1. 1FireFailure to fire stops here
  2. 2ExtractFailure to extract stops here
  3. 3EjectCase thrown clear
  4. 4FeedFailure to feed stops here
  5. 5Chamber and lockReady to fire again
What the trainer says

Here's the cycle from lesson 2 again, with the three malfunctions on it. Failure to fire breaks it at the very first step. Failure to extract breaks it when the case should come out. Failure to feed breaks it when the next round should go in. Picturing where the cycle stopped helps you see what to check.

What to do

Two dangers to know

CompareHangfireSquib load
What happensThe cartridge fires late, after the clickThe shot sounds or feels much weaker than normal
The dangerOpening the action as it firesA bullet stuck in the barrel
What you doMuzzle safe, wait at least 30 secondsStop firing; check the barrel is clear before any more shots
What the trainer says

Two special cases. A hangfire is a cartridge that fires late, a moment after the click. If you open the action just then, it can injure you, which is why you wait at least 30 seconds with the muzzle downrange. A squib load is a cartridge that fires weakly, with a quiet pop or little recoil. The bullet may be stuck in the barrel. Stop firing. If you fire another round behind a stuck bullet, the barrel can burst. Make the rifle safe and have the barrel checked before you shoot again.

What to do

Fix it yourself, or see a gunsmith?

ProblemWho deals with it
Magazine not fully seatedYou: reseat it and check
Dirt in the chamber or actionYou: clean it with a cleaning kit
One faulty cartridgeYou: put it aside safely, as your range requires
Broken or worn extractorA gunsmith
The same malfunction again and againA gunsmith
A bullet stuck in the barrelA gunsmith, or a recognised expert
What the trainer says

The unit standard asks you to know which fixes are yours and which go to a gunsmith. Yours: reseating a magazine, cleaning dirt out of the chamber or action, and setting a faulty cartridge aside safely as the range requires. A gunsmith's: a broken or worn part such as an extractor, any malfunction that keeps coming back, and a bullet stuck in the barrel. If in doubt, make the rifle safe and take it to a gunsmith.

At Ridgeview

Thandi's rifle stops mid-string

Halfway through a string, Thandi's bolt closes on nothing: the next round hasn't fed.

  • Muzzle downrange, finger off
  • The magazine wasn't fully seated
  • She clears it as Anel showed her, reseats and tugs the magazine
What the trainer says

Halfway through a string, Thandi presses the trigger and gets a click. The bolt has closed on an empty chamber: the next round never fed. She keeps the muzzle downrange, takes her finger off the trigger and tells Anel. The cause is simple: the magazine wasn't fully seated. She clears the rifle the way Anel showed her for her model, reseats the magazine and gives it a tug. No gunsmith needed. A failure to feed she can fix herself.

Next

Your turn

Before lesson 8

  • Do the exercise: What went wrong?
  • Answer four quick questions on this lesson
  • Apply: ask your trainer to show you the drill for your model
Next: inspection, cleaning and the practical test.
What the trainer says

Name the malfunction in each scene, then answer four questions. Ask your trainer to show you the clearance drill for your rifle, and practise it with dummy rounds if your range allows. Next lesson: inspection, cleaning, and exactly what the practical assessment asks.
