Assembling a shotgun should be a straightforward process, but sometimes you encounter unexpected problems. One frustrating issue is an internal jam in the barrel during assembly. This can be caused by several factors, ranging from simple misalignment to more serious mechanical problems. This guide will explore the common causes of this issue, provide troubleshooting steps, and offer preventative measures to ensure smooth and safe assembly every time.
Common Causes of Internal Jams During Shotgun Assembly
Several factors can contribute to an internal jam when assembling your shotgun:
-
Obstructions in the barrel: This is the most common cause. Small pieces of debris, such as cleaning patches, bits of ammunition, or even a small tool, can become lodged inside the barrel, preventing the assembly of the receiver and barrel.
-
Misalignment of the barrel and receiver: If the barrel isn't properly aligned with the receiver, it can create interference and prevent it from seating correctly. This is often due to rushing the assembly process or not paying close attention to the alignment.
-
Damaged parts: A bent or damaged barrel lug, a deformed receiver, or other damaged components can obstruct the assembly process, leading to a jam. This usually requires professional repair or replacement.
-
Improper lubrication: Lack of proper lubrication can cause friction and hinder smooth movement during assembly. Conversely, excessive lubrication can attract and trap debris.
-
Manufacturing defects: While rare, manufacturing defects in the barrel or receiver can cause assembly issues.
Troubleshooting Steps for a Shotgun Barrel Jam
If you encounter an internal jam, follow these steps carefully:
-
Safety First: Always ensure the shotgun is unloaded and pointed in a safe direction. Double-check!
-
Visual Inspection: Carefully inspect the barrel's exterior and interior (using a bore brush or cleaning rod if necessary) for any visible obstructions. A flashlight can be helpful.
-
Gentle Attempts at Removal: Try to gently wiggle the barrel and receiver, ensuring proper alignment. Avoid excessive force, which could damage the firearm.
-
Rod and Patch: If you suspect a small obstruction, use a cleaning rod and a bore patch to attempt to remove it. Work slowly and carefully to avoid pushing the obstruction further into the barrel.
-
Professional Assistance: If you cannot remove the obstruction or if you suspect damage to the firearm, seek professional help from a qualified gunsmith. Attempting to force the assembly can cause irreparable damage.
Prevention is Key: Tips for Smooth Shotgun Assembly
Preventing jams is always better than dealing with them. Here are some preventative measures:
-
Cleanliness: Regularly clean your shotgun thoroughly after each use. This removes debris and prevents build-up that could cause jams.
-
Proper Lubrication: Apply a thin layer of gun oil to the appropriate parts during assembly. This reduces friction and ensures smoother movement.
-
Careful Assembly: Take your time and pay close attention to proper alignment during assembly.
-
Regular Inspection: Regularly inspect your shotgun for any signs of damage or wear and tear. Address any issues promptly to prevent potential problems.
-
Storage: Store your shotgun in a clean, dry environment to minimize the risk of debris accumulation.
When to Seek Professional Help
If you've followed the troubleshooting steps and are still unable to resolve the jam, or if you suspect any damage to your firearm, don't hesitate to contact a qualified gunsmith. They possess the expertise and tools to diagnose and repair the problem safely and effectively. Improper handling can lead to injury or further damage to your firearm. Remember, safety always comes first.
