AR 15 Firing Pin: The Ultimate Guide to Function and Maintenance

Featured in:

The AR-15 firing pin is an essential component of any AR-15 rifle. This small but mighty part plays a critical role in the weapon's ability to fire and operate effectively. As such, it is crucial for gun owners to understand how their firing pins work, what types are available, and how they can maintain them properly.

Firing pins come in various sizes and materials depending on factors like the manufacturer, model of the firearm, and whether you're using parts designed for competition or everyday use. It's important to note that different firing pins may also interact with different types of ammunition differently – some harder primers may require a tougher pin than others.

Maintaining your AR-15 firing pin is crucial if you want your rifle to stay reliable over time. Neglecting this tiny yet essential part can lead to malfunctions during shooting sessions or even permanent damage that requires expensive repairs or replacements down the line. In this article, we'll dive deeper into everything you need to know about AR-15 firing pins so you can keep your weapon running smoothly for years to come.

AR 15 Firing Pin: A Comprehensive Guide

If you're a gun enthusiast and you own an AR-15 rifle, then the firing pin is one of the most important components of your firearm. It's responsible for striking the primer on your cartridge, which ignites the gunpowder and propels your bullet downrange. As such, it's crucial to understand what a firing pin is and how it works.

What is an AR 15 Firing Pin?

The firing pin in an AR-15 is a small metal rod that sits inside the bolt carrier group (BCG). When you pull back on the charging handle, it retracts the BCG and compresses a spring behind the firing pin. Once released, this spring launches forward with great force – striking against your cartridge’s primer.

Types of Firing Pins

There are two main types of firing pins available for use in an AR-15 rifle – mil-spec or enhanced:

  1. Mil-Spec: These are standard-issue components made to military specifications.
  2. Enhanced: These come with better finishes as well as improved materials like titanium nitride coatings or chrome lining.

While both types will function correctly in most situations when they’re properly maintained; enhanced pins tend to be more durable thanks to their superior construction quality.

Benefits Of Using An Enhanced Firing Pin

An enhanced-firing-pin-equipped rifle can offer benefits beyond just durability:

  1. Smooth Trigger Pulls: The lighter weight reduces trigger pull weight thus providing smoother operability.
  2. Less Wear And Tear On Other Components: The reduced pressure means less wear-and-tear on other rifle parts like springs or bolts.
  3. Better Ignition Time – By reducing lock time between hammer release & ignition; ensuring better accuracy whilst also reducing recoil.

Maintenance And Inspection

Maintenance plays a crucial role in keeping any firearm running smoothly – including its various components such as its firing pin. Consistent cleaning and lubrication will keep it functioning correctly over time.

To inspect your firing pin, remove the BCG from your AR-15 rifle and look for any signs of damage or wear in the area where the firing pin sits. Check that there are no burrs or cracks along its surface – these imperfections can lead to a misfire or other malfunctions.


In conclusion, an AR-15 firing pin is a small but crucial component of any rifle – as it’s responsible for igniting your rounds reliably while absorbing high impact forces repeatedly over time. If you're looking to upgrade yours; then consider purchasing an enhanced-firing-pin which will improve both consistency & durability for better shooting results at all times!


What is an AR-15 firing pin?

The AR-15 is a popular semi-automatic rifle that is widely used by hunters, sportsmen, and firearms enthusiasts. The firing pin in the AR-15 is a small metal rod that sits inside the bolt carrier group. When you pull the trigger on your rifle, it releases the hammer which then strikes the firing pin. The impact of this strike causes it to move forward and hit the primer in the cartridge case that ignites gunpowder within it.

In short, an AR-15 firing pin plays an essential role in initiating combustion within your firearm's chamber to enable propulsion of bullets from its barrel.

How important are quality and correct sizing for my ar 15 firing pins?

Quality and proper sizing are two essential aspects when considering purchasing or replacing your ar 15's Firing Pin. Quality Firing Pins ensure they withstand heavy use without wearing out quickly; they should be durable enough to resist extensive wear caused by repeated cycling under normal usage conditions.

Proper Sizing ensures smooth operation with minimal friction build-up between moving parts responsible for initiating each round's ignition process efficiently.

When shopping around for replacement options or upgrading your current setup, always consider investing in high-quality products recommended explicitly by manufacturers like Brownells or other reputable brands specializing in firearms accessories.

No! It would not be safe nor appropriate installing any other type of Firing Pin intended explicitly for different models such as Ar10/308 Winchester rifles into Ar – 5 Rifles since both have entirely distinct dimensions regarding their bolt carriers; using incompatible types could result inadequacies leading up to potentially hazardous scenarios when operating these firearms.

It’s crucial always to consult experts' advice who specialize specifically in offering comprehensive guidance on Identifying compatible parts before performing any installation processes on your AR-15 rifle.

Can I use a damaged or worn-out firing pin in my Rifle?

No! It is not advisable to use damaged or worn-out Firing Pins as they compromise the firearm's safety, leading up to potential hazards during usage. Worn-out parts could cause misfires, and in worst-case scenarios failure to ignite round discharging from your rifle; this can be dangerous for you and those around you while handling firearms.

It’s crucial always ensuring that all components within the gun are well-maintained, inspected regularly for damage before using them. Any defective systems identified should be replaced immediately with high-quality products available on reputable stores specializing specifically in firearms accessories such as or other specialty shops carrying a myriad of products catering explicitly towards enthusiasts' needs who enjoy shooting sports like hunting, target shooting among others.

How often do I need to replace my ar 15 firing pins?

The frequency of replacing an Ar-15 Firing Pin depends mostly on usage levels and factors like how frequently it's fired under rough conditions that might cause excessive wearing out between moving parts over time.

Generally speaking, it’s good practice always keeping track of how many rounds have been discharged through your firearm after every use; this will help determine when regular maintenance schedules are due based on individual user requirements unique situations involving their rifles.

However, experts recommend purchasing high-quality replacement kits available online at various specialty retailers catering towards hunters' needs for regular replacements every 5k – 10k rounds firer through the gun based exclusively on personal preference.
