AR-15 Hammer Spring Orientation: The Ultimate Guide

Whether you are a seasoned gun enthusiast or just starting with firearms, the AR-15 is undoubtedly one of the most popular and versatile semi-automatic rifles available in the market. The AR-15 is renowned for its accuracy, reliability, and ease of customization. However, like any firearm mechanism, it requires proper maintenance to ensure optimal performance.

The hammer spring orientation is an essential aspect of maintaining your AR-15 rifle. In this article, we will guide you through everything you need to know about the hammer spring orientation for your beloved rifle.

What Is An Ar-15 Hammer Spring?

Before diving into the details of hammer spring orientation let us first understand what a hammer spring does in an ar 15 rifle. A hammer spring serves as a power source that pushes on the firing pin by coiling up like a clock's mainspring when compressed inside its housing tube.

The release journey from full compression allows energy transfer that propels forward by striking off at high speeds towards ammo leaving behind enough energy to ignite primer thereby initiating combustion which ultimately leads to shooting bullets out from barrel end muzzle.

In simple words without suitable tension provided by ar 15 trigger return springs and ensuring correct positioning during assembly/disassembly can lead to poor firing mechanisms leading thereby reducing performance output over time.

Why Is Hammer Spring Orientation Important?

Hammer springs play an essential role in ensuring proper functioning of your firearm while shooting rounds. Properly assembled hammerspring helps maintain tension level needed for trigger reset after each shot fired thus allowing quicker follow-up shots without delay due broken or misaligned components present within gun triggers systems which can hinder their functionality if not addressed timely resulting decreased accuracy rates among other issues associated directly affecting user experience.

How To Check Your Ar-15 Hammer Spring Orientation

It's imperative always knowing whether assembled correctly following manufacturer guidelines during disassembly/ Assembly procedures since incorrect installation may result failure perform optimally including missing rounds, misfires jams leading gun malfunctions.

One easy way to check for correct assembly of your hammer spring orientation is to examine the two legs. The longer leg should be on the right and the shorter one on the left side when placed in position.

You can also test it by pulling back on your charging handle and releasing it while keeping an eye on how far forward or backward your hammer moves before returning up into place after being compressed against its housing tube inside receiver end area located near above trigger guard section.

Tips For Proper Hammer Spring Orientation

Here are some tips that will help you maintain proper hammer spring orientation for optimal performance from your ar 15 rifle:

  1. Follow manufacturer guidelines – Always follow manufacturer guidelines while disassembling or assembling any firearm. This ensures you don't miss any critical steps, including correctly positioning components such as a hammer spring.
  2. Use proper tools – Always use appropriate tools as improvised materials can lead to damage or misalignment of parts during assembly/disassembly processes leading negative impact overall durability over time.
    3.Ensure Correct Positioning- Ensure correct positioning of legs during installation always ensure longer leg placed towards right side with shorter leg placed towards left side when installed properly ensuring smooth functioning without any hindrance causing malfunctioning directly affecting user experience negatively.


The ar-15 rifle is undoubtedly one of the most popular firearms available today, but like all mechanical systems requires maintenance from time-to-time for optimal performance output ensuring accuracy rates among other factors remain top-notch at all times.

Hammer springs are an essential aspect need addressing timely if not addressed could lead malfunction resulting decreased performance output/accuracy rate thereby affecting user experience negatively ultimately hampering positive shooting experiences over long period timespan due deteriorating mechanism parts present within trigger system that require attention need addressing promptly so they do not impede functionality later down line which affects quality control standards set forth making sure rifles meet highest levels possible.

By following manufacturer guidelines and properly orienting your hammer spring, you can ensure that your ar-15 rifle functions optimally, providing unrivaled shooting experiences every time without delay or malfunction thereby allowing users to enjoy their firearm for years to come.


What is the correct orientation for an AR-15 hammer spring?

The AR-15 hammer spring orientation is critical to proper function and reliability of the firearm. The hammer spring should be installed with the open end facing forward towards the front of the rifle. This ensures that the coil opens in a way that allows it to compress when struck by the trigger.

Installing it incorrectly can cause several issues, including failure to fire or misfires, as well as damage to other internal parts of your firearm. It's important to take your time during this process and ensure you are installing everything correctly.

Additionally, if you have any concerns about installation or functionality after installation don't hesitate to seek out professional help from a qualified gunsmith.

Can I install an AR-15 hammer spring myself?

Yes, installing an AR-15 hammer spring yourself is possible provided you have some experience with firearms and know how they operate mechanically. However, if you're not confident in your ability or lack experience working on firearms then having a professional gunsmith handle this task would be advisable.

It's crucially important that everything inside your firearm works properly since malfunctioning parts could create dangerous situations while shooting either for yourself or those around you who might be nearby at range sessions etcetera

Furthermore, even experienced individuals may find themselves struggling with certain types of springs like these because they can be quite challenging due their shape which makes them hard get into place without damaging them

What happens if I install my ar 15 Hammer Spring backwards?

If installed backward (with its closed end facing forward), it will cause malfunctions ranging from light strikes – where only primer dents are visible but no ignition – all way up until complete failure-to-fire scenarios

In addition such reverse installation also increases wear-and-tear on other components found inside lower assembly such as sear engagement surfaces et cetera due increased force placed upon them whenever firing pin moves rearward before striking primer which will ultimately lead their failure over time

How can I tell if my AR-15 hammer spring is installed correctly?

The best way to verify the correct installation of your AR-15 hammer spring is by conducting a function check on your fire control group. Once you have reassembled the lower receiver, manually pull the charging handle back and release it while holding down on the trigger.

If everything works correctly, you'll hear a loud click or thud sound as your hammer drops onto an imaginary firing pin (since there's no live ammunition in gun during this process). You should feel some resistance against trigger until sear releases hammer. If it does not pass test smoothly or feels gritty in any way then something's wrong that needs immediate attention.

It's highly recommended that before testing anything out like this for real, users double check all parts are installed according OEM specs (including springs) and rifle has been properly cleaned & lubricated beforehand too

Do I need any special tools to install an AR-15 Hammer Spring?

No special tools are required for installing an AR 15 Hammer Spring other than standard drive punches or roll-pin punch set which can be found at most gun shops.

However having dedicated tool like Wheeler Engineering Delta Series AR Armorer’s Professional Kit provides extra convenience because it comes with specific tools needed firearm disassembly/reassembly including vise block sets which helps secure lower receiver during assembly process reducing risk damage scratches et cetera
