Best AR 15 Lower Receiver

What is AR 15 Lower Receiver? 😏

It is the foundation of any AR-15 rifle build. It’s a metal component that provides the housing for all other parts of the gun and is often thought of as a frame or receiver.

Here is the video about the general information regards choosing AR-15 lower receiver 💻

Features 💡

🔰 One key feature to consider is whether or not the lower receiver is forged or billet. Forged receivers are more common amongst most manufacturers and are generally preferred by rifle builders due to their strength and durability. This type of receiver has been stamped from sheet metal under great force to form its shape. On the other hand, billet receivers are cut from solid blocks of aluminium, providing a higher level of craftsmanship for those looking for a personalized look.

🔰 Another feature to consider is compatibility with different trigger parts. Most commonly referred to as mil-spec, this indicates whether or not certain parts will fit within your lower receiver’s housing without any modifications or special tools needed. Many aftermarket triggers often require modification in order to fit inside non-mil-spec receivers. However, some manufacturers have developed modernized versions that do not require additional modifications in order to be compatible with most aftermarket triggers on the market today.

🔰 In addition, you’ll need to consider if you want multi-calibre capability with your lower receiver. There are some models which allow for easy conversion between different calibres by simply changing out components such as bolt carrier groups and magazine catch as well as other parts depending on the calibre chosen. With this option available, you can build one rifle that will conveniently switch calibres depending on your needs with the minimal additional effort required from you as the builder/shooter.

🔰 Finally it’s beneficial to consider how much customization you would like on your lower receiver itself. There are many options available ranging from simple engraving options up to full custom cerakote finishes in almost any colour imaginable – allowing users to truly express themselves through their guns with unique designs while still maintaining structural integrity thanks to modern manufacturing processes and coatings technologies used today!

Benefits 🔥

  • 📣 Durability and longevity. Lower receivers are made from high-grade aluminium, often with additional reinforcements and hard coat anodizing for extra strength. This makes them much more robust than other components, such as upper receivers or handguards, so you can rest assured that your rifle will remain durable even after high-volume firing sessions or harsh environmental conditions.
  • 📣 In terms of customization potential, no part offers as much variety as the lower receiver. Much like its upper counterpart, there are countless different styles available on the market ranging from basic mil-spec designs to heavily customized units with unique colours and patterns. Best of all, many companies offer matching sets that allow users to mix and match components across different models for maximum flexibility when customizing their rifles. Furthermore, certain model variations come equipped with features such as integral trigger guards for improved safety during use or integrated stock adapters for easy conversion between fixed and collapsible stocks.
  • 📣 Finally, another benefit is its compatibility with parts from various manufacturers. With most parts having adopted standardized dimensions over time it has become easier than ever before to source compatible components from a variety of sources rather than relying on just one manufacturer’s catalogue.

Types 📢

⌛ The most common type is forged lower receivers. They are created by compressing and shaping a single block of heated aluminium or another metal alloy under intense pressure. This process creates a strong and durable lower receiver with precise tolerances that ensure an improved fit and function compared to standard plastic or composite models.

Billet lower receivers are also popular because they are machined from a single block of aluminium, creating precise tolerances for superior fit and function. Polymer lower receivers offer improved strength and durability compared to traditional aluminium lowers and are often lighter in weight as well.

The stripped lower receiver is an important component of any AR-15 build since it’s the foundation upon which all other components will be built. A stripped lower includes only the basic parts needed to finish out your rifle—the fire control group (trigger, hammer, disconnector), safety selector switch, magazine release button, buttstock interface system (buffer tube) and pistol grip threading. As such, it offers a great starting point for customizing your own AR-15 rifle with aftermarket parts.

Each type has its advantages and disadvantages depending on what you’re looking for in your rifle build. Considerations include strength/durability versus weight savings; customization options; cost; accuracy; fitment compatibility; overall look/aesthetic appeal; ease of installation/assembly; available accessories; and more. Research carefully before selecting the Receiver that best fits your needs!

FAQ 😎

Is it better to buy or build an AR?
It really depends on what you’re looking for. If you are an experienced gunsmith and like working with tools, then building a AR 15 lower receiver can be a great way to customize your firearm and get the exact specifications that you want. However, if time or experience is an issue, then it would be better to buy one already assembled since it will likely cost less and save time in assembly. Ultimately, the decision is up to you – weigh the pros and cons of both options before making your choice!
What parts are in a lower receiver?
The lower receiver of a AR 15 rifle is made up of several parts, including the trigger guard, magazine release button, hammer and trigger assembly, selector switch/safety lever, buffer tube housing for the recoil spring and buffer system, takedown pins, stock plate and screws for attaching a buttstock. Additionally, some models come with provisions for adding a pistol grip or other custom accessories.
How to build a lower receiver?

🔴 To begin, you will need the following tools: a drill press, a Dremel tool or jig, safety glasses, and a set of files. Once you have gathered these items, you can start the process of constructing your own lower receiver.

📌 The first step in building your own lower receiver is to measure and mark the parts for drilling. You will need to measure and mark for two trigger holes, two selector holes, two hammer pins and two takedown pins. It’s important that these measurements are accurate because if they are not measured correctly it could affect the function of your AR-15 rifle.

📌 Once your parts are properly marked, you can start drilling out the trigger holes using a drill press. After this is complete, use a Dremel tool or jig to finish up any edges that may be left around the hole from drilling. During this process, it is essential to wear safety glasses in order to protect your eyes from metal shavings and other debris.

📌 After all of the holes have been drilled and finished up with the Dremel tool or jig, it’s time to install all of the components.

  • Begin by inserting the hammer pin into its designated hole and securing it with epoxy glue or a thread locker compound.
  • Next, insert each selector switch into its respective hole and secure it with epoxy glue or thread locker compound as well.
  • Finally, insert both takedown pins into their respective holes and secure them with epoxy glue or thread locker compound again before affixing either piece of Velcro strips on each side for easy removal when needed.

📌 Now that all of the components have been successfully installed you can begin attaching other parts like furniture such as grips and hand guards as desired. Installing additional furniture parts such as stocks will also require additional hardware elements such as screws so make sure you’re prepared for that step in advance as well!

📌 Finally, after any additional furniture pieces are installed onto your lower receiver it’s time to test-fire it at an outdoor range before installing any optics systems onto it if desired!

I hope this video will help all the beginners💻

What is the difference between striped and complete receivers?

The difference between a stripped and a complete lower receiver is that the stripped receiver requires additional components to be fully assembled.

🏴 Stripped receivers are made up of only the essential parts required to build an AR-15 and must have all other necessary components (trigger assembly, buffer tube, stock and grip) added separately.

🏴 Complete receivers come with all of these same parts pre-assembled and factory tested before delivery, making them easier to use without any extra work needed. Additionally, when purchasing a complete lower receiver you know that all components are compatible since it was already built by an experienced gunsmith or machine shop ensuring perfect fitment for your AR platform.

Which is a better polymer or aluminium AR lower?

Both have their pros and cons, so each person must take into consideration their own needs and preferences when deciding which type of lower receiver is best for them.

🎌 One of the main advantages of using an aluminium lower receiver is that it offers superior strength and durability compared to a polymer one.

🎌 The metal material is also less prone to deformation or wear and tear over time.

🎌 Additionally, aluminium AR lowers are usually more aesthetically pleasing due to their sleek designs and smooth finish. However, they tend to be heavier than comparable polymer ones, making them less ideal for shooters who prefer lightweight firearms.

🎌Polymer AR lowers offer several advantages as well. They are usually much lighter than aluminium versions, which makes them great for shooters looking for mobility and portability in their firearms.

🎌Additionally, because they use a plastic material, they tend to be much more affordable than traditional metal receivers.

🎌Finally, some polymer receivers also feature increased accuracy when compared with aluminium versions due to the more precise moulding process used during production.

What is better - forged or billet lower receiver?

When considering what type of lower receiver is best for a AR 15, it is important to understand the differences between a forged and billet lower receiver.

💠 A forged lower receiver is formed by taking a piece of aluminium and heating it up until it is hot enough to be moulded into the shape of a lower receiver. The advantage of a forged receiver is that it has been compressed under intense heat, making it extremely durable and less likely to crack or break. This type of construction also makes it less expensive than its billet counterpart.

💠 On the other hand, billet lower receivers are typically made from a single piece of aluminium that is cut out using CNC (computer numerical control) machines. This method allows manufacturers to craft complex shapes and designs with greater precision than with a forging process. While this can create attractive designs, billet receivers tend to be more costly than their forged counterparts due to their longer manufacturing times.

When deciding which type of AR 15 lower receiver will suit your needs best, there are several factors that should be taken into consideration.

✅ Forged receivers offer excellent strength at an affordable price point, making them ideal for those who plan on using their AR 15 for recreational shooting or hunting purposes.

✅ If you’re looking for something that offers more customizability in terms of design, then a billet receiver might be better suited for you as these can easily be machined into intricate shapes and patterns.

✅ Additionally, if you are planning on building a rifle that requires tight tolerances then opting for a billet option might give you the accuracy needed in order to hit your target reliably every time.

Conclusion🤩

While choosing AR Lower Receivers, check the quality of finish, completeness (what is included or not), reviews about missing parts (rare cases or frequent ones), and compatibility with AR builds. Usually, detents and springs are quite the same, while magazine releases and safety selectors can vary a bit.😀🧡

My first build was made even more enjoyable with the discovery of a set screw for the bolt catch release on my Aero lower. I’m sure I’m not alone in feeling relieved to not have to tackle driving a rolling pin into that small hole! It might seem insignificant, but it’s moments like this that make building all worthwhile – because sometimes it really is the little things in life that count.
