AR 15 Mil Spec Buffer Tube: The Ultimate Guide for Gun Enthusiasts

Featured in:

The AR 15 Mil Spec Buffer Tube, a crucial component of the popular AR-15 rifle, is an essential part that gun enthusiasts and tactical shooters should not overlook. This buffer tube serves as the interface between the stock assembly and the lower receiver. Without it, there would be no way to attach a buttstock to your AR-15.

Mil-Spec Buffer Tubes are built with specific requirements in mind to ensure compatibility with other parts of your weapon system. These tubes come in different lengths and profiles for various types of firearms. You can choose from either commercial or mil-spec versions depending on what type of gun you have.

In this article, we will delve into everything you need to know about AR 15 Mil Spec Buffer Tube components -what they are made up of, what makes them unique compared to other buffers on the market today -and how they function within an assembly setup. So if you're interested in learning more about this important part for your firearm set-up stay tuned!

AR 15 Mil Spec Buffer Tube: The Ultimate Guide

If you're an AR 15 enthusiast, then you know the importance of having a high-quality buffer tube. It's one of the most crucial components that make up your rifle's lower receiver assembly. In this guide, we'll dive deep into what makes a mil-spec buffer tube so special and why it's worth investing in.

What is a Mil-Spec Buffer Tube?

A mil-spec buffer tube is built to meet specific military standards. It must adhere to these standards to ensure it's compatible with other components used by the military. These requirements include dimensions, material specifications, and more.

The primary purpose of the buffer tube is to house the recoil spring and buffer assembly within an AR 15 rifle or pistol build. This component provides support for the stock or brace while also allowing for proper cycling of rounds through your firearm.

With that said – not all buffers tubes are created equal. So what sets apart a mil-spec from any other? Let’s find out!

Differences between Mil-Spec & Commercial Buffer Tubes

Mil-spec is often confused with commercial-grade parts because they look similar at first glance but have several differences :

Characteristic Mil-Spec Commercial
Length Fixed (7") Adjustable (6" – 10")
Thread Pattern Threads on outside Threads on inside
Diameter Tapered Straight

Mil spec tubes only come in one size which has fixed length at around seven inches long whereas commercial ones can be adjusted between six inches long up to ten inches long depending on preference.

Another difference comes from their thread patterns; mil specs use threads located externally as opposed where commercial models utilize threads found internally instead making them incompatible without significant modification beforehand like adjusting bore height etcetera!

Lastly, mil-spec tubes have a tapered design which enables them to lock into numerous lower receivers securely. Commercial ones are not tapered but instead feature a straight design that allows for easy installation and removal.

Benefits of Using Mil-Spec Buffer Tubes

One of the primary benefits you’ll enjoy with using mil-spec buffer tubes is that they're engineered with quality in mind. You can expect them to last longer than their commercial counterparts because they're built to withstand harsh conditions.

Another advantage is compatibility; since military-grade parts must meet specific standards, you can rest assured knowing your buffer tube will work seamlessly with other components designed for military use.

Mil-spec buffer tubes are also more ergonomic compared to commercial models. They’re made from aircraft-grade aluminum, which makes them lightweight yet durable enough to handle recoil forces effectively.

Tips on Choosing the Right Mil-Spec Buffer Tube

When shopping around for a new buffer tube, there are several factors you should consider:

  1. Length: Determine what length works best based on your preferences and shooting style.
  2. Material: Look for high-quality materials like aircraft-grade aluminum or steel.
  3. Brand Reputation: Stick with reputable manufacturers who specialize in producing high-quality AR-15 components.
  4. Compatibility: Ensure any aftermarket add-ons or modifications match up perfectly before making your purchase!

Conclusion

In conclusion, investing in an AR 15 Mil spec Buffer Tube is one of the smartest investments you could make as it drastically improves both performance and durability while being compatible across countless aftermarket parts! So whether you're building an AR-15 pistol or rifle build – be sure not only choose wisely but also do some research beforehand too so that way all bases covered when selecting what works best!

FAQs

What is an AR 15 Mil Spec Buffer Tube and why do I need it?

The AR 15 Mil Spec Buffer Tube, also known as the receiver extension tube, is a critical component of an AR-15 rifle. The buffer tube houses the recoil spring and buffer assembly, which are responsible for absorbing recoil when shooting. It also serves as a mounting point for various parts of the rifle.

A mil-spec buffer tube has specific dimensions that are standardized by the military. This means that it should be compatible with any other mil-spec parts in your rifle build or upgrade project. Having a well-made mil spec buffer tube can help ensure reliable function and durability.

If you're building or upgrading your AR-15 rifle, having a high-quality Mil-Spec Buffer Tube will help to provide long-lasting service life on this crucial component and improve overall performance.

What materials are used to make an AR 15 Mil Spec Buffer Tube?

Most commonly made from aluminum alloy stock — though polymer options exist too — Anodized Aluminum offers excellent corrosion resistance along with good strength-to-weight ratio making them ideal for use on firearms components such as receiver extensions/buffer tubes (or even entire receivers). Often described as Type III Hardcoat Anodizing because of its thickness requirements per military specifications (MIL-A-8625), this process provides increased surface hardness and wear resistance compared to non-anodized material surfaces without adding significant weight gain.

Can I use commercial stocks on my MIL-SPEC Lower Receiver?

Mil-spec lower receivers tend to have tighter tolerances than their commercial counterparts which results in some differences between corresponding components such as stocks being interchangeable between lower receivers manufactured using either type specs.

When dealing with firearm components compatibility is key – so while you can attach some commercial style stock options onto your MIL SPEC Lower Receiver Assembly – results may vary depending upon fitment tolerance considerations given each individual product design characteristics unique unto itself i.e., buffer tube diameter, length, etc.

What is the difference between AR 15 Commercial and Mil-Spec Buffer Tubes?

The primary difference between commercial and mil-spec buffer tubes lies in the shape of their threaded section. Commercial tubes have a slanted back while Mil-spec are flat. Additionally, commercial diameter is larger than mil-spec (1.170" vs 1.148").

Mil-Spec components are specifically made for military use – they’re subject to very strict specifications regarding dimensional tolerances that ensure reliable functionality with other parts of an AR rifle system designed to fit these same standards; while commercially produced options may not be held to such stringent requirements.

Can I install a MIL SPEC buffer tube onto my AR-10 or .308 Rifle?

While many features of an AR-15 might seem interchangeable with its big brother – The AR-10 / LR308 rifles – it’s important to note this isn’t always the case! Though some parts such as triggers might interchange between platforms without issue there still exists variance among models even within each platform type that can lead compatibility issues arising when attempting swaps within different configurations – especially true for critical components like receiver extensions/buffer tubes where size & specs matter!

So if you're considering upgrading or making changes on your firearm build/upgrade project involving MIL SPEC Lower Receiver Assembly components (such as replacing its current Buffer Tube), make sure you take into account your specific model type's unique characteristics before proceeding any further.
