AR-15 Fixed Stock Buffer Tube Kit: Upgrade Your Rifle Today

Featured in:

The AR-15 rifle is undoubtedly one of the most popular rifles in the world. It's no surprise that gun enthusiasts and collectors alike are always searching for ways to improve their rifles' performance. That's where the AR-15 fixed stock buffer tube kit comes into play.

This kit is a crucial component of any AR-15 build, as it provides stability and helps reduce recoil when firing. The buffer tube itself attaches to the lower receiver and houses a spring-loaded buffer which absorbs much of the recoil from firing your rifle. The fixed stock then attaches to this tube, providing balance and customization options for length-of-pull adjustments.

If you're an avid shooter or simply looking to upgrade your existing AR-15, then you'll want to read on as we dive deeper into everything there is to know about this essential component: The ar-15 fixed stock buffer tube kit.

AR-15 Fixed Stock Buffer Tube Kit: An Essential Component for Your Rifle

When it comes to rifles, the AR-15 is one of the most popular choices among gun enthusiasts. Whether you are an experienced shooter or a beginner, having a well-functioning rifle is crucial to your success on the range or in the field. One of the essential components of any AR-15 is its buffer tube kit.

What Is an AR-15 Fixed Stock Buffer Tube Kit?

The buffer tube kit consists of several parts that work together to control and absorb recoil when firing your rifle. These parts include a buffer spring, a buffer tube (also known as a receiver extension), and either an adjustable or fixed stock. The fixed stock option provides stability and consistency in shooting while reducing weight.

As its name suggests, an ar-15 fixed stock buffer tube kit includes all these parts with one exception – it isn't adjustable like other options available in the market.

Benefits of Using an AR-15 Fixed Stock Buffer Tube Kit

The benefits of using this type depend on what kind of shooting you plan to do:

  1. Stability & Accuracy: A solidly built fixed-stock can offer better stability than some adjustable ones since there's no chance for misalignment between parts during movement that may influence accuracy.
  2. Reliability: Unlike collapsible stocks which have multiple moving components that often require frequent maintenance checks due to wear & tear caused by constant adjustment; with fewer moving pieces involved, using fix-stocks requires less upkeep.
  3. Reduced weight: Because they are designed without adjustability hardware inherent within collapsible variants such as screws or pins required from adjustments — using this component reduces unnecessary additional bulkiness making them lighter overall compared against their alternatives.

Using this particular combination provides greater control over recoil movements thereby reducing felt recoil significantly compared against other options available keeping sensitive users' comfort levels in mind.

Comparing Adjustable vs Non-adjustable Buffer Tube Kits

One of the main differences between adjustable and non-adjustable buffer tube kits is the ability to adjust length-of-pull. Adjustable stocks can be modified for more comfortable shooting positions, which is great if you're sharing your AR-15 with someone who has a different body type or preference than yours.

However, if you prefer a specific fixed length-of-pull, then an ar-15 fixed stock buffer tube kit becomes much more appealing. It also reduces overall weight and increases stability in comparison to its adjustable counterpart.

Tips for Choosing and Installing an AR-15 Fixed Stock Buffer Tube Kit

If you are looking to purchase an ar-15 fixed stock buffer tube kit, here are some tips that may help:

  1. Check Compatibility: Ensure that your chosen product fits perfectly with your rifle before purchasing it.
  2. Look For Quality: Purchase from reputable manufacturers like Aero Precision or Bravo Company who offer high-quality products within this category.
  3. Seek Professional Assistance: If possible seek professional installation guidance while installing these components as they involve extensive knowledge regarding tools & techniques required during assembly/disassembly processes involved in setting these pieces together effectively without any complications post-installation.


The ar 15 fixed stock buffer tube kit plays a crucial role in controlling recoil when firing your rifle while offering greater control over accuracy than other options available on the market today by reducing additional bulkiness and increasing stability making them lighter overall compared against their alternatives.

Whether you're planning on hitting targets at the range or going out into nature for hunting season soon – this component should always remain top of mind during any maintenance checkups because no matter how experienced one is? performance will always depend upon fundamental essentials such as using high-quality equipment like what we've covered here today!


What is an AR-15 fixed stock buffer tube kit and why do I need it?

An AR-15 fixed stock buffer tube kit is a set of components that are used to attach the rifle's buttstock to the lower receiver. It consists of a buffer tube, recoil spring, castle nut, end plate and sometimes includes other accessories such as a sling attachment point or rubber buttpad. The fixed stock version differs from its collapsible counterpart in that it does not have an adjustable length of pull.

The main advantage of using a fixed stock over collapsible one is increased stability. Whereas the collapsible stocks offer flexibility for adapting to different shooting positions and situations, they can also introduce wobble into your aim which can lead to accuracy issues. With the lack of moving parts in the design, fixing your stock will ensure consistent alignment with your sights or optic; improving accuracy while reducing fatigue during prolonged shooting sessions.

What are some things I should consider when selecting an AR-15 fixed-stock buffer tube kit?

When choosing between different models on today's market there are several factors you may want to take into account before making your purchase:

Material: There are two primary materials used in constructing these kits: aluminum alloy and polymer plastic compounds. While aluminum tubes tend towards durability under heavy use conditions (such as law enforcement training), polymer variants offer lighter weight options for casual shooters.

Attachment methodology: Different manufacturers use varying methods for securing their tubes onto receivers – Some utilize threads along their exterior surfaces where others might require proprietary tools for installation/removal.

Length & profile type: Depending on intended usage or personal preferences you might want to choose between Rifle-Length(13 1/2" OAL), A2 Profile(9 5/8" OAL)or Carbine Length(7", 10", etc.) variants

Durability rating: Ensure that any product you select has been tested according applicable standards for safety, strength and recoil absorption.

Compatibility: While some kits may be designed to fit a wide range of AR-15 platform rifles, others are more specialized in their fitment. It is important that you double-check the compatibility with your lower receiver before making a purchase.

Can I replace buffer tubes on my own without any professional assistance?

Yes, it is possible to install an AR-15 fixed stock buffer tube kit by yourself if you have the necessary tools and basic technical skills. That said, it's important to note that this process requires removing the previous components from your rifle which can necessitate using specialized tools or jigs to avoid damage during removal (such as action blocks). Once removed however installation of your new kit should be relatively straightforward with most users able complete these steps within a few hours.

Are there any legal requirements for owning an AR-15 fixed stock buffer tube kit?
