Common Diamondback AR-15 Problems And Their Solutions

1. Failures To Feed

Failures to feed can be caused by various issues, ranging from feeding problems with the magazine to ammunition malfunctions.

But fear not, as this problem has solutions that can be easily implemented with some basic knowledge and practice.

Feed failures can occur for several reasons, including dirty or damaged magazines or damaged or improper ammunition. In some cases, the rifle itself may be the culprit.

Neglecting regular cleaning and maintenance of the rifle may also lead to feeding issues. It’s important to understand that these issues can be easily resolved with some troubleshooting and regular maintenance.

To fix a failure to feed, start by thoroughly cleaning the rifle and magazines. This should be done regularly to prevent dirt and debris buildup.

The magazine should also be checked for damage or signs of wear. If the magazine is damaged, it may need to be replaced.

If the ammunition is the issue, it may be due to improper storage or using cheap or low-quality ammunition. Properly store your ammunition to avoid moisture and damage.

If the above steps do not resolve the issue, the rifle itself may need to be checked by a professional gunsmith.

They can diagnose any issues with the rifle and make necessary repairs or recommend further maintenance.

2. Failure to Fire

Are you familiar with the “Failure to Fire” concept regarding firearms? It’s frustrating when a firearm fails to ignite a round when the trigger is pulled, leaving the shooter with an unresponsive weapon.

This can be caused by various factors, including issues with the ammunition, firearm, or user error.

One of the main causes of Failure to Fire is a problem with the ammunition. This can include using old, improperly stored, or damaged rounds.

It can also be caused by using the wrong type of ammunition in the firearm.

Additionally, inadequate primer strikes or a faulty firing pin can also cause a Failure to Fire situation.

If the issue is with the ammunition, the solution is simple: replace the problematic rounds with new, high-quality ones.

However, if the problem is with the firearm itself, it will require some troubleshooting and potentially some repairs.

First, ensure that the firearm is properly maintained and cleaned regularly. Make sure that all components are properly lubricated and that there is no buildup of dirt or debris.

Check the firing pin for any damage or wear, and replace it if necessary.

If the issue persists, it may be worth seeking the help of a professional gunsmith. They will be able to diagnose the issue and provide appropriate repairs or replacements. 

3. Failures to Extract

Failure to extract occurs when the spent casing remains stuck in the chamber after the round has been fired.

This results in a jammed firearm that doesn’t allow you to fire another round, causing you to disassemble the firearm and fix the issue. 

The main causes of failure to extract can be improper maintenance, worn or damaged components, or ammunition issues.

Failing to clean your AR-15 regularly can lead to the accumulation of debris in the chamber, causing an obstruction that prevents the empty casing from being ejected properly.

Worn or damaged extractors can also contribute to the issue. Additionally, using low-quality ammunition or improperly sized cartridges can lead to a failure to extract. 

Luckily, there are steps you can take to fix this issue. First, ensure that your firearm is clean and properly lubricated before firing.

This can prevent debris from building up in the chamber and causing obstructions.

Inspect your extractor and replace it if you notice any wear or damage.

This can improve the gripping power of the extractor, allowing it to pull the spent casing out of the chamber more effectively.

Lastly, ensure that you use your firearm’s proper ammunition size and quality. Refer to the manufacturer’s guidelines for recommended ammunition and sizes.

4. Over-Gassing

Are you experiencing increased recoil and excess wear on the rails of your Diamondback AR-15? If so, you may be dealing with a common problem known as over-gassing.

Over-gassing occurs when an excessive amount of gas is directed back into the rifle’s action during firing, which leads to increased pressure, recoil, and wear on the rails.

Several main causes for over-gassing include using an incorrect gas block or buffer system, an improperly installed gas block, or inconsistent ammunition.

If you suspect that your rifle is over-gassed, it is important to remedy the problem before it causes long-term damage to your firearm or impairs your shooting accuracy.

One of the most effective solutions for addressing over-gassing is to adjust your rifle’s gas system by modifying the gas block or installing a new buffer system.

This process involves several steps, including removing the gas block, selecting the appropriate replacement components, and reassembling the rifle with the appropriately modified gas system.

It is important to note that modifying your gas system requires a certain level of technical skill and knowledge, so it is advised to seek guidance or assistance from a qualified gunsmith or firearms expert.

Additionally, while adjusting the gas system may vary depending on the specific issue at hand, following established best practices and safety guidelines is essential to ensuring that the work is performed safely and accurately.

5. Accuracy Issue

The main causes of accuracy issues with the Diamondback AR-15 can be attributed to a variety of factors.

Firstly, poor quality ammunition can lead to inconsistent accuracy. Another culprit can be inadequate maintenance.

The rifle’s barrel must be cleaned and maintained to ensure maximum accuracy.

Finally, incorrect techniques or lack of training can also contribute to accuracy problems.

To address these accuracy issues, there are several steps you can take. Firstly, pay close attention to the quality of ammunition you are using.

Ensure that the ammunition is of high quality and that it is stored properly. Secondly, ensure you follow the recommended maintenance routine for your rifle. 

This includes cleaning the barrel and other components with the correct products and tools.

Lastly, consider seeking professional training to improve your technique or practicing at a shooting range to become more familiar and comfortable with your weapon.

6. Jamming

Jamming refers to the failure of a firearm to cycle properly. A jam can occur when the next round of ammunition fails to load correctly, causing a stoppage or failure to fire.

Multiple factors, including poor maintenance, weak ammunition, faulty magazines, or operator error can cause jams.

To fix a jam, the first step is to ensure the firearm is pointed in a safe direction and unloaded.

Disassemble the rifle and inspect the chamber for any debris or obstructions.

Clean the chamber, bolt face, and carrier group thoroughly with solvent and a soft cloth. Ensure the gas system is functioning correctly, and the gas rings on the bolt are in good condition.

Next, check the magazine to ensure it’s in good condition, clean, and properly loaded. Sometimes, a faulty magazine will cause feeding issues, resulting in a jam.

Try another magazine and see if the issue persists. If the rifle continues to malfunction, check the ammunition you’re using. Weak or poorly manufactured ammunition is a common cause of jams.

Try using a different brand and see if the rifle functions correctly.

Finally, ensure you’re using the correct technique when operating the firearm. Pull the charging handle all the way to the rear and release it to chamber a round.

Don’t ride the charging handle forward, as this can cause a partial chambering of the round and lead to jamming.
