If you’re a GunBuilders looking to build your own AR 15 rifle, you need the right parts for the job. Whether you’re an experienced gunsmith or a novice just getting started, having the right AR 15 parts is critical for the success of your build. In this blog post, we’ll provide a comprehensive overview of the various components that make up the AR 15 and explain why each one is important.
The Lower Receiver
GunBuilders are well aware of the importance of a good quality lower receiver for their AR 15 build. The lower receiver is the part of the rifle that houses the trigger, hammer, and other fire control components, as well as the magazine release and safety selector. It is also the part of the rifle that must be purchased from a federally licensed firearm dealer, as it is considered a “firearm” under U.S. law.
When selecting an AR 15 lower receiver, there are several things to keep in mind. First, be sure to pick one made from 7075-T6 aluminum alloy, which is strong and lightweight. Second, look for a hard coat anodized finish to increase corrosion resistance. Third, make sure the trigger guard is large enough to accommodate gloves, or consider buying an enlarged one if not included with the lower receiver. Finally, if you’re building a left-handed rifle, look for an “ambidextrous” lower receiver, or buy an ambidextrous magazine release separately.
Once you’ve picked out your lower receiver, the next step is to install the parts and assemble the lower. For this step, GunBuilders need a quality AR 15 parts kit to provide all the necessary pins, springs, and other components. This can also include an adjustable trigger, depending on the particular kit you choose. Following manufacturer instructions and using the right tools (which may include punches and a vise), assemble the lower and make sure everything functions correctly before moving on to the upper receiver.
The Upper Receiver
One of the most important AR 15 parts is the upper receiver. It is the component that houses the bolt carrier group and the barrel. The upper receiver also serves as the point of attachment for the handguard, sights, optics, and other components. There are two main types of upper receivers: forged and billet.
Forged upper receivers are created through a manufacturing process where metal is heated until it is malleable and then hammered or pressed into its desired shape. This process is usually used when creating lower receivers as well. Forged upper receivers are typically considered to be the stronger and more durable option.
Billet upper receivers are machined from a solid block of aluminum which makes them lighter than their forged counterparts. Because they’re machined from a solid block, billet upper receivers often have more intricate designs that include fluting, more angle cuts, and custom engravings.
When shopping for an upper receiver, it’s important to consider the intended use of your AR-15 build. If you’re looking for an AR-15 for home defense, a forged upper receiver will provide the strongest and most reliable build. However, if you’re building an AR-15 for competition shooting, a billet upper receiver may be more appropriate because of its light weight and stylish design. No matter what your needs are, there’s an upper receiver that will fit your specific build!
The stock is one of the most important AR 15 parts, as it serves as a platform for the shooter to rest their shoulder against when firing. When it comes to building an AR 15, the stock you choose will affect the overall length of your rifle and its overall weight, making it an important choice. Some popular stocks include fixed stocks, adjustable stocks, and collapsible stocks. A fixed stock is usually made of solid wood or plastic and provides no adjustability, while an adjustable stock allows the shooter to customize the length of pull or cheek weld height. Collapsible stocks are typically made of durable polymer and provide extra flexibility for the user. The type of stock you choose will depend on your intended use and shooting style.
