AR-15 Troubleshooting: Next Round Failing to Cycle – Solutions and Fixes

Featured in:

AR-15 not cycling next round. If you are familiar with firearms, you know the frustration that comes with this problem. Whether it's on the range or in a life-threatening situation, your AR-15 rifle not cycling can be disastrous.

The AR-15 is a popular firearm among gun enthusiasts and military personnel alike due to its reliability and accuracy. However, even the most well-made rifles can experience malfunctions at some point in time. When your AR-15 fails to cycle after firing, it could be due to several reasons such as improper maintenance or damaged parts.

If you're experiencing this issue with your AR-15 rifle and wondering what could have gone wrong, don't worry! In this article, we will explore the various factors that cause an AR-15 not to cycle properly after shooting and provide practical solutions for each of them. So keep reading!

AR-15 Not Cycling Next Round: Troubleshooting Tips

If you're a gun enthusiast, owning an AR-15 is a must-have. It's versatile, user-friendly and customizable to meet your preferences. However, even the most advanced guns can experience issues that require troubleshooting. One common issue experienced by AR-15 owners is the failure of the gun to cycle on the next round after firing.

This problem can be frustrating and lead to delays when hunting or practicing at the range. In this article, we will explore some of the reasons why your AR-15 may not be cycling on its next round after firing and provide tips on how to troubleshoot it.

Causes of Failure in Ar 15 Cycle

  1. Dirty Gas System

The gas system plays a crucial role in ensuring that your rifle cycles correctly through every shot fired without failings between rounds – if there’s carbon buildup (or any other debris) present in this area from previous use then it could interfere with proper functioning leading up until things just stop altogether.

To fix this issue:

* Disassemble all parts including upper receiver group
* Clean all components thoroughly using solvent or oil 
    - Paying close attention t0 areas where carbon build-up is likely.
* Reassemble components back into firearm ensuring everything fits snugly together before testing again
  1. Worn Out Buffer Spring Or Damaged Buffer:

The buffer spring in an ar 14 ultimately helps regulate recoil – which aids with cycling ammo properly; however if damaged or corroded as well as being worn out over time from use then problems are bound to happen eventually .

To fix this issue:

  • Replace buffer spring very carefully insuring correct installation
  • Inspect for damage on current buffer componentry (contact expert assistance if needed)
  1. Magazine Problems

More often than not when you’re experiencing issues with cycling ammo it’s because magazine has failed expectations during use. A faulty magazine could lead to misalignment within the bolt carrier group causing a stoppage in cycling through your firearms system.

To fix this issue:

  • Try using a different magazine
  • Check for any damage, misalignments or deformations of current magazines used
  1. Gas Block Misalignment

The gas block is responsible for regulating the amount of gas that enters and powers up all parts in your firearm; if it’s even slightly out of alignment, then every other componentry will be affected as well leading to issues with cycling rounds consistently.

To fix this issue:

  • Disassemble upper receiver group
  • Inspect gas block – determine if properly aligned
    • If not take professional assistance or try reinstallation accurately before testing again


In conclusion, troubleshooting an AR-15 that won't cycle on its next round after firing can be challenging but rewarding once you identify and resolve the root cause. As seen above there are several factors involved so you should never give up hope when trying to solve such issues rather seek help whenever possible including manufacturer assistance – just keep working through each potential problem until everything is finally fixed!


What causes an AR-15 to not cycle the next round?

If you are experiencing a failure of your AR-15 to cycle the next round after firing, there could be several reasons for this problem. One possible cause is that your gas system is not functioning correctly. Your rifle's gas block may be misaligned or obstructed, causing inadequate gas flow to operate the action. Another potential issue could be that your bolt carrier group (BCG) is dirty and has become clogged with carbon buildup from use.

Another common reason why an AR-15 might fail to eject or load another round is due to weak ammunition that does not generate enough force for reliable cycling. This particular issue can occur if you're using lower-powered rounds for practice purposes instead of full-power rounds like those used in matches and competitions.

Lastly, a worn out buffer spring can also prevent your rifle from cycling properly as it gradually loses its tension over time making it unable to provide adequate energy needed by the BCG during recoil operation.

How do I fix my AR-15 when it fails to cycle the next round?

The first step in addressing an "AR-15 Not Cycling Next Round" issue would involve checking whether all connections between parts are tight and secure before attempting anything else. Ensure no obstructions prevent movement in parts such as chamber area or barrel extension tube assembly which would cause ejection malfunctions leading into similar problems during cycling operations too!

If everything seems fine internally but still won't fire normally after troubleshooting steps taken above then consideration should turn toward examining individual components: Check bolts/bolt carriers groups (BCGs) themselves – ensure proper engagement within upper receiver housing when installed correctly according manufacturer guidelines; Inspect specially designed areas within BCGs where carbon buildup may accumulate inhibiting natural movement; replace failing buffer springs immediately upon discovery so future issues don't arise unexpectedly while out at range practicing either alone or alongside friends/family members.

What is the gas system of an AR-15 and how does it work?

The AR-15 operates on a direct impingement or gas piston system – meaning that after firing, combustion gases generated by the round are used to push the bolt carrier group back into its rearward position.

In direct impingement systems, some of this gas is channeled through a small hole in your rifle's barrel and directed towards an expansion chamber located above where BCGs are held. This then drives BCGs which in turn powers cycling operations (like ejection/loading) as they move forward under spring tension toward next round waiting within magazine well upon reaching end cycle position.

Gas piston systems operate utilizing similar methods but instead utilize separate parts such as pistons actuated directly by pressurized gases themselves rather than just using them secondarily for movement like with DI operation.

How can I prevent my AR-15 from not cycling next round?

There are several steps you can take to prevent your AR-15 from failing to cycle properly. For starters, ensuring proper maintenance of individual components such as buffer springs and bolts/bolt carriers groups will reduce likelihood for mechanical malfunctions during use over time due to natural wear-and-tear.

Regular cleaning sessions after range trips or heavy usage periods also helps minimize buildup inside critical areas like chambers/barrel extension tubes helping keep everything running smoothly overall without prolonged accumulation issues leading into more serious ones down road!

Lastly, when purchasing ammo make sure it meets specifications for appropriate power too so there won't be any issues with weakly-loaded rounds causing failures during operation either!

Can I fix my own AR-15 if it is having trouble cycling?

Yes! As long as you have basic knowledge about firearms mechanics requiring minimal tools available at home or nearby local gunsmith shop most people should be able troubleshoot their own rifles when experiencing problems related directly toward "AR-15 Not Cycling Next Round" issues.

However, If symptoms worsen or persist even after initial troubleshooting steps have been taken (such as inspections of buffer springs or bolt carriers groups), it may be best to take your rifle in for professional repair. A knowledgeable gunsmith can assess whether any more serious underlying problems exist and suggest necessary repairs before an accident occurs leading potentially dangerous situations/outcomes with firearms use later down road.
