Understanding the AR 12S
The Charles Daly AR 12S. It’s a shotgun that’s become a staple in the firearm community. Its semi-automatic action, combined with its AR-15 inspired design, has attracted a loyal following of enthusiasts and sport shooters. However, like any complex mechanical device, the AR 12S can encounter its share of problems. This article aims to provide a comprehensive guide for owners, delving into common issues, offering practical solutions, and providing essential maintenance tips to ensure your AR 12S operates smoothly and reliably.
Addressing Failures to Feed
A failure to feed, often abbreviated as FTF, is a frustrating experience for any shooter. It’s when the next round fails to be properly loaded from the magazine into the chamber, interrupting the firing sequence. This can happen for a variety of reasons, each requiring a systematic approach to diagnose and resolve.
Magazine Issues
One of the most common culprits is a magazine issue. The magazine itself plays a critical role in the feeding process. Problems can arise from several factors, including a damaged follower. The follower is the component that pushes the rounds upwards; if it’s worn, cracked, or obstructed, it can prevent the round from properly presenting itself to the chamber. Weak or damaged magazine springs are another major issue. A spring that has lost its tension might not have enough power to push the rounds up quickly enough. Inspect the lips of your magazine for damage. They can be bent or spread, creating issues when feeding rounds into the chamber. Ensure that the lips are aligned and undamaged. Also, the body of the magazine itself can cause problems. Dents or damage might prevent the magazine from sitting correctly in the firearm or might hinder the proper movement of the rounds within the magazine.
Ammunition Compatibility
Another key factor is the ammunition. The AR 12S, like any firearm, is designed to work with specific types of ammunition. The specifications of the rounds might not be compatible. Low-brass shells, for instance, might not always generate enough energy to properly cycle the action. Always use ammunition that meets the manufacturer’s specifications. In some cases, experimentation might be required. Using different brands or types of ammunition will help diagnose and alleviate FTF issues.
Bolt Carrier Group Maintenance
A dirty or improperly lubricated bolt carrier group also causes this issue. The bolt carrier group is responsible for extracting, ejecting, and chambering rounds. A build-up of carbon, dirt, or debris, or a lack of lubrication, can hinder the smooth functioning of the bolt. This friction impedes its movements. Ensuring that the bolt carrier group is thoroughly cleaned and properly lubricated is a critical aspect of preventing and solving FTF. The correct lubricant will reduce friction, allowing for smooth cycling.
Gas System Evaluation
Gas system problems also have a link to failure to feed. In a gas-operated firearm, the gas system diverts some of the expanding gases from the fired round to cycle the action. Improper gas block alignment or insufficient gas pressure can disrupt this process, hindering the bolt carrier group’s ability to cycle the next round. To address this, inspect the gas block for proper alignment. Ensure that it is seated correctly and seals effectively. A gas leak will lead to insufficient gas pressure.
Solving Failure to Eject Problems
A failure to eject, often indicated as FTE, is when the spent casing remains in the chamber or does not properly leave the firearm after firing. This, like FTF, can quickly bring your shooting session to a halt.
Ejector Inspection
Weak or damaged ejectors often cause this. The ejector, a small but essential component, is responsible for pushing the spent casing out of the chamber. A damaged or worn ejector may fail to function correctly. A damaged ejector cannot provide the required force to eject the spent shell.
Extractor Diagnosis
Faulty extractors are also known culprits. The extractor grabs the rim of the spent casing, pulling it from the chamber. If the extractor is damaged, worn, or fails to grip the casing correctly, FTE issues are likely. A weakened grip prevents it from properly pulling the spent casing out.
Gas System Issues and Lubrication
A dirty or malfunctioning gas system, contributing to insufficient gas pressure, might also result in FTE. If the system doesn’t have adequate pressure, the bolt carrier group won’t cycle far enough back to allow the extractor to properly do its job.
Another factor to address is the level of lubrication. Insufficient lubrication within the moving parts of the firearm increases friction. This friction makes the extraction process difficult.
Mitigating Failures to Fire
A failure to fire, often abbreviated as FTF, is when the firing pin does not ignite the primer on the shell, preventing it from firing. Various factors can lead to this issue.
Light Primer Strikes
Light primer strikes are the most common reason. This happens when the firing pin does not strike the primer with enough force to ignite the gunpowder. A weak or worn hammer spring does not generate enough force to drive the firing pin forward. This might happen because the spring’s tension has decreased.
Firing Pin and Trigger Mechanism Considerations
Dirty or damaged firing pins might also contribute. A dirty or partially blocked firing pin channel can hinder the free movement of the firing pin. This would prevent it from striking the primer with enough force. Damage to the firing pin itself can prevent proper primer ignition.
Broken firing pins would cause the round not to fire. A broken firing pin will fail to ignite the primer. It must be replaced.
A malfunctioning trigger mechanism is a less common, but possible issue. If the trigger mechanism is malfunctioning, it might not release the hammer correctly, leading to an FTF situation.
Dealing With Magazine Specific Troubles
As the main feeder of rounds, magazines are often a source of frustration for AR 12S owners. Several issues can disrupt the consistent operation of these essential components.
Magazine Spring Problems
Weak magazine springs are the most likely culprits. After repeated loading and unloading, these springs can lose their tension and weaken. This reduces their ability to push rounds upwards fast enough, leading to feed issues.
Magazine Condition
Damaged feed lips can create issues with feeding. When the feed lips are bent or cracked, they might not hold the rounds at the correct angle for proper feeding.
Any dent or damage to the magazine body can distort its shape. This might affect the magazine’s ability to fit correctly in the firearm and can impede the smooth movement of rounds.
The wrong magazine fit will cause feed issues. There are different types of magazines that might not be compatible with every AR 12S model.
Understanding Gas System Related Issues
The gas system is critical for the smooth operation of any gas-operated firearm, including the AR 12S. Malfunctions within this system can lead to reliability issues, affecting both feeding and ejection.
Gas Block Alignment
Improper gas block alignment can cause malfunctions. Gas blocks must be accurately aligned to ensure that the right amount of gas pressure is being diverted to operate the action.
Carbon Buildup
Buildup of carbon within the gas system will also cause issues. Regular shooting will create carbon buildup inside the gas tube and the gas block. This buildup can restrict the flow of gas, reducing the pressure needed to cycle the action correctly.
Gas Leaks
Gas leaks are another common problem. Leaks from the gas block or around the gas tube will decrease the gas pressure. It is essential to regularly inspect these components for any signs of leaks.
Maintaining and Caring for Your AR 12S
Regular maintenance and care are essential for the longevity and reliability of your Charles Daly AR 12S.
Cleaning Schedule
Cleaning your AR 12S should be done on a regular schedule. After each shooting session, it’s recommended. Regular cleaning prevents the build-up of residue that can cause malfunctions.
Lubrication Practices
Lubrication is also critical. Apply lubricant to the bolt carrier group, the moving parts, and any other areas where metal rubs against metal. Use a high-quality gun oil or lubricant designed for firearms. This minimizes friction.
Regular Inspections
Inspecting the firearm regularly is essential for detecting issues. Regularly examine all parts. Check for wear and tear, damage, or signs of corrosion. Pay particular attention to the bolt carrier group, the extractor, and the ejector.
Storage Guidance
Storing the firearm properly is essential. Store your AR 12S in a dry and secure location. Using a gun safe is a good practice. Proper storage is critical for preventing corrosion and protecting the firearm.
Safety First
Always prioritize firearm safety. This is an essential component. Treat every firearm as if it is loaded. Always point the muzzle in a safe direction, and keep your finger off the trigger until ready to shoot.
Follow all applicable laws and regulations regarding the ownership, storage, and use of firearms. Adhering to these laws ensures responsible gun ownership and helps to maintain public safety.
These precautions are critical to safe gun handling.
