Crush Washer for AR 15: The Essential Guide

Featured in:

Looking for the right equipment to maintain your AR 15 can be a daunting task. However, one of the most important and often overlooked components are crush washers. A crush washer is a small but crucial piece that helps ensure the proper alignment and stability of certain parts in an AR 15.

Without a properly installed crush washer, it can lead to issues such as gas leaks or issues with timing which can ultimately cause malfunctions during use. As such, it's vital that you have high-quality crush washers that fit correctly when replacing or installing new parts on your AR 15.

In this article, we will delve deeper into what exactly is a 'crush washer' for an AR 15 rifle and why they're so important in ensuring safe operation of your firearm. We will discuss how they work, their types available on market along with their installation process. Read on to learn more about this essential component!

What is a Crush Washer for AR 15 and Why Do You Need It?

When it comes to assembling or disassembling an AR-15, one of the essential components that you will come across is a crush washer. This small circular piece plays a vital role in ensuring that your muzzle device stays securely attached to your barrel. In this article, we will delve deeper into what exactly a crush washer for AR 15 is and why it's necessary.

What Is A Crush Washer For Ar 15?

A crush washer is commonly used with muzzle devices like flash hiders, compensators or suppressors on AR-15 rifles. It's made from high-quality steel material that can withstand high pressure without breaking down. The washers come in various sizes depending on the diameter of your barrel and the type of muzzle device you are using.

The name "crush" implies how the washer works; when you install it between your muzzle device and barrel threading, its purpose is to deform once tightened against each other firmly – hence crushing together – hence creating tension between both parts which helps keep them secure through recoil forces.

Why Do You Need A Crush Washer For Ar 15?

If you're wondering why exactly having this small component matters so much when assembling an AR-15 rifle, then here are some reasons:

Proper Alignment

One significant benefit of using a crush washer during installation ensures proper alignment between the threads on both parts being attached together (muzzle device & barrel), which means preventing any potential gas leaks as well as malfunctioning due to inadequate alignment during use resulting from incorrect installation.

Secure Attachment

Another reason why it's crucial always to have this tiny component at hand while installing any muzzle devices onto barrels fitted onto an AK47-type platform such as an ArmaLite Rifle model number fifteen (AR-015) platform) has been attributed by experts primarily due two factors:

  1. Tension
    When a crush washer gets installed between your muzzle device and barrel threading, it deforms to create tension. This tension is crucial because it helps keep both parts secure through recoil forces. It keeps the components from rotating against each other during firing cycles thus preventing misalignment or detachment which can lead to catastrophic failure.

  2. Heat Resistance
    Another advantage of using high-quality steel materials in making Crush washers is their ability to resist deformation due to heat generated by continuous firing cycles while hunting, engaging targets in training exercises or competitions.

Compliance with Legal Requirements

In many countries around the world including the United States of America, having a crush washer installed on your AR-15 rifle muzzle device (flash hider or compensator) could be part of compliance requirements depending on local laws governing firearms-related use & ownership issues.

How To Install A Crush Washer For Ar 15

Now that you understand what this small component does and why it's necessary let's go over how you can install a crush washer for AR-15 rifles:

  1. First things first, ensure that your hands are clean and dry before starting any assembly procedure involving firearms parts; safety comes first!
  2. Next up thread on the flash hider onto your barrel without tightening completely.
  3. Place the crush washer onto its threads behind your flash hider.
  4. Use an adjustable wrench such as pliers carefully holding one side of your suppressor so that it remains stationary while tightening down onto another side against which pressure will be applied until sufficient resistance builds up indicating successful installation completion – no need for excessive force here since overtightening might cause damage rather than ensuring security during operation times should anything go wrong later down range.

Conclusion

Crush washers are essential components needed when installing muzzle devices like flash hiders or compensators securely onto barrels fitted into AK47-type platforms such as ArmaLite Rifle model number fifteen (AR-015) platform. They play a significant role in ensuring proper alignment, heat resistance and compliance with legal requirements governing firearms-related use & ownership issues globally. If you're looking to install one yourself, make sure that your hands are clean and dry before starting the installation procedure involving firearms parts for safety purposes.

FAQs

What is a crush washer for AR 15 and what does it do?

A Crush washer is a small metal ring used to ensure proper alignment of the muzzle device on an AR-15 rifle. It's designed to be compressed when it's torqued down, which helps provide a tight fit between the barrel and muzzle device. This serves two purposes: first, it ensures that gases are directed correctly through the flash hider or compensator; second, it helps prevent any loosening of the device during use.

The crush washer itself usually has several layers which allow for some flexibility during installation. The idea is that as you tighten down the muzzle device onto your barrel, these layers compress together until they form one solid piece. This compression creates enough tension between your barrel threads and your muzzle device threads to keep everything secure while you shoot.

Can I reuse my old crush washers?

It's generally not recommended to reuse old crush washers because they're designed specifically for one-time use. Once compressed during installation, their ability to provide adequate tension may be compromised if reused again in subsequent installations.

In addition to this risk factor, reusing them can also lead to problems with alignment or torqueing – both of which can create issues with accuracy or even safety concerns by allowing hot gasses from firing escape in unintended directions.

Therefore, always make sure you have a fresh new crush washer each time you install a new muzzle brake on an AR 15 rifle.

How do I install my AR-15 Crush Washer?

Installing an AR-15 Crush Washer isn't difficult but requires some attention-to-detail in order for success.
Here are general steps involved:

  1. First remove any existing flash hider/compensator from your rifle by unscrewing it counterclockwise using suitable tools such as vice grips etc.
  2. Clean up both threads (barrel & Muzzle Device)
  3. Take out new crush washer from the package and slide it over the threads on your barrel. Make sure that it is correctly oriented with the beveled side facing towards muzzle.
  4. Next, screw your new muzzle device onto your barrel threads by hand until it's snug.
  5. Then use a wrench and tighten down to specified torque requirements or manufacturer’s recommendations (usually 15-20 ft-lbs).
  6. Re-tighten 1/4 turn after shooting about 50 rounds

Always ensure correct orientation of Crush Washer before tightening down to prevent any misalignment.

Can I install my AR-15 Crush Washer without a Vice?

Yes, you can definitely install an AR-15 Crush Washer without using a vice. But it may require extra effort when compared to using one.

The easiest way to do this would be with specialized tools like armorers wrenches which have flats designed for attaching directly onto muzzle devices while still leaving room for other tools such as torque wrenches or pliers if necessary.

When you don't have these specialized tool kits available, adjustable spanners (wrenches), vise grips etc could also help in tightening down although they may not provide as much leverage during installation process as that of armorer’s wrench.

Are all crush washers same size for AR 15 rifles?

No! There isn’t just one universal model of an ar-15 crush washer; there are many different sizes depending on what kind of devices you’re installing on your rifle – flash hiders versus compensators – even within those categories there can be differences in thread pitch between manufacturers!

Therefore, always make sure you check with manufacturer specifications before purchasing any replacement parts so that everything fits perfectly together once installed properly.

In conclusion:
A good quality CRUSH WASHER is important whenever installing muzzle device like Flash Hider / Compensator etc.. A proper fit helps direct gases away from shooter and maintain accuracy during firing sessions. Make sure to have a new crush washer for each installation to ensure best results and safety.
