AK-47s and their variants are known for their robust design and reliability. However, even these battle-proven rifles can experience malfunctions. One frustrating issue is a trigger that fails to reset after firing, leading to inability to fire subsequent shots. This problem, often referred to as an AK trigger not resetting, can stem from several causes, ranging from simple issues to more complex mechanical problems. This comprehensive guide will walk you through the common causes, troubleshooting steps, and potential solutions to get your AK back up and running smoothly.
Understanding the AK Trigger Mechanism
Before diving into troubleshooting, it's crucial to understand the basic mechanics of an AK trigger. The AK-47's trigger mechanism is relatively simple yet effective. The trigger itself interacts with the disconnector, hammer, and sear. When the trigger is pulled, it releases the sear, allowing the hammer to fall and fire the round. The disconnector then prevents the hammer from falling again until the bolt carrier group (BCG) fully cycles and resets. This crucial resetting action is at the heart of the problem when your AK trigger isn't resetting.
Common Causes of an AK Trigger Not Resetting
Several factors can prevent your AK trigger from resetting correctly. These range from simple issues easily resolved at home to more serious problems requiring professional gunsmithing.
-
Dirty or Damaged Trigger Parts: Accumulated dirt, debris, or carbon fouling can interfere with the smooth operation of the trigger group components. Similarly, damage to any part of the trigger mechanism—the trigger itself, the sear, the disconnector, or the hammer—can also prevent proper reset.
-
Improper Trigger Installation or Adjustment: If you've recently worked on your AK's trigger group, incorrect installation or adjustment of the trigger components is a significant potential cause. Even a slight misalignment can prevent the parts from interacting correctly.
-
Worn or Broken Trigger Parts: Over time, constant use can wear down trigger components, particularly the sear and disconnector. Excessive wear can lead to malfunction, including failure to reset. A broken component is a more severe issue requiring replacement.
-
Ammunition Issues: Although less common, problems with the ammunition, such as weak primers or improperly seated bullets, can indirectly impact trigger reset. A failure to cycle the BCG completely due to a malfunctioning round can prevent the trigger from resetting.
-
Bolt Carrier Group (BCG) Issues: Problems with the BCG, such as a malfunctioning gas system or excessive friction, can hinder its proper cycling. If the BCG does not fully cycle, the disconnector won't reset the trigger.
Troubleshooting Your AK Trigger
Troubleshooting an AK trigger that won't reset involves systematic checks and potential fixes. Safety should always be your top priority. Always ensure the weapon is unloaded and pointed in a safe direction.
1. Visual Inspection and Cleaning
Begin by performing a thorough visual inspection of the trigger group. Look for:
- Visible Damage: Check for any obvious damage to the trigger, sear, disconnector, or hammer. Look for broken parts, excessive wear, or signs of bending.
- Dirt and Debris: Use a cleaning rod, appropriate solvents, and brushes to remove any dirt, carbon fouling, or debris. Pay particular attention to areas where the trigger components interact.
2. Functionality Check
With the weapon unloaded, carefully manipulate the trigger and observe its movement. Check for any binding or unusual resistance. If you find any binding, investigate the potential points of friction.
3. Disassembly and Detailed Inspection
If the visual inspection and cleaning don't resolve the issue, a more in-depth inspection will likely be needed. This might require partial or complete disassembly of the trigger group. Refer to a reputable AK disassembly guide specific to your rifle's model. Improper disassembly can cause more damage.
During disassembly, carefully examine each component for wear, damage, or any signs of malfunction.
4. Addressing Specific Issues
Depending on the findings during your inspection, you might need to address specific problems:
- Worn parts: Replace worn or damaged components with original manufacturer parts or high-quality aftermarket replacements. Never use substandard parts, as this can compromise the rifle's safety and reliability.
- Misalignment: Carefully realign and reinstall components. If you lack the experience or tools to do this safely, seek the assistance of a qualified gunsmith.
- Broken parts: Repair or replace the broken components. This usually necessitates contacting a qualified gunsmith for repair and replacement.
Prevention and Maintenance
Regular maintenance is key to preventing trigger reset issues.
- Regular Cleaning: Clean your AK after each shooting session or at least every few months. Regular cleaning prevents dirt and debris from accumulating and interfering with the trigger mechanism.
- Proper Lubrication: Use a high-quality gun lubricant to lubricate the trigger group components, ensuring smooth operation. Don't use excessive lubricant, as this can attract dirt and grime.
- Careful Handling: Avoid dropping or mishandling your AK, as this can cause damage to internal components, including the trigger group.
When to Seek Professional Help
If you're unable to identify the cause of the trigger reset problem or are uncomfortable disassembling and repairing the trigger group, consult a qualified gunsmith. Attempting repairs without the proper knowledge and tools can lead to further damage and compromise the safety of your firearm.
This comprehensive guide provides a step-by-step approach to troubleshooting an AK trigger that is not resetting. Remember always prioritize safety and consult a professional if you're unsure about any aspect of the repair process. Maintaining your AK-47 through proper cleaning and regular inspections will help prevent future malfunctions.
