Top 5 Tips for Choosing the Right Components for Your AR15 Lower Receiver Build

Building an AR15 lower receiver from scratch can be an incredibly rewarding experience for any gun enthusiast. It allows for a level of customization and personalization that off-the-shelf firearms simply cannot match. However, with the myriad of components available on the market, choosing the right parts for your build can be a daunting task. To ensure that your AR15 lower receiver meets your expectations in terms of performance, aesthetics, and reliability, here are the top five tips to guide you through the selection process. First and foremost, start with a solid foundation by selecting a high-quality lower receiver. The lower receiver is the backbone of your AR15, housing the fire control group, magazine well, and providing attachment points for the stock and grip. It’s crucial to choose a receiver that is made from durable materials such as forged or billet aluminum. Forged receivers are typically stronger due to the hammering process they undergo, which aligns the grain of the metal, while billet receivers offer more intricate designs and tighter tolerances due to being machined from a single block of aluminum. Regardless of your choice, ensure that the receiver is manufactured to precise specifications for a good fit with other components. Next, consider the trigger assembly, which is a critical component for achieving a crisp and clean pull. The market offers a wide range of triggers from single-stage to two-stage, and from mil-spec to competition-grade with varying pull weights. A single-stage trigger is straightforward and consistent, ideal for most shooting scenarios, while a two-stage trigger offers a more predictable break, which can be beneficial for precision shooting. When selecting a trigger, think about your intended use for the rifle and choose a trigger that complements your shooting style. Moving on to the buffer system, which plays a significant role in the cycling of your ar15. The buffer and buffer spring work together to absorb recoil and return the bolt carrier group into battery after firing. It’s important to match the buffer weight to your specific build, especially if you’re using a non-standard caliber or barrel length. A heavier buffer can reduce felt recoil and improve cycling, but it may require a stronger spring. Conversely, a lighter buffer might increase the rate of fire but could also lead to reliability issues. Strike a balance that suits your build and intended use. The selection of the stock is another aspect that should not be overlooked. Stocks come in various styles, from fixed to collapsible, and the choice often depends on the shooter’s needs and preferences. A fixed stock is sturdy and reliable, providing a consistent cheek weld for precision shooting. On the other hand, a collapsible stock offers versatility and adjustability for shooters of different sizes or those who need to operate in confined spaces. Consider the ergonomics, length of pull, and the materials used in the stock to ensure comfort and functionality. Lastly, don’t forget about the grip. It might seem like a minor component, but the grip significantly affects your shooting experience. It should fit comfortably in your hand and provide a secure hold to maintain control during rapid firing sequences. Grips come in various shapes, sizes, and materials, with features like finger grooves, palm swells, and texturing to enhance grip. Some even offer storage compartments for small items like batteries or tools. Choose a grip that feels natural and complements the overall ergonomics of your rifle. In conclusion, building an AR15 lower receiver is a complex task that requires careful consideration of each component. By starting with a quality receiver, selecting a trigger that suits your shooting style, balancing the buffer system, choosing the right stock for your needs, and finding a comfortable grip, you can assemble a lower receiver that is tailored to your preferences and ready for any challenge. Remember, the key to a successful build is in the details, so take your time, do your research, and enjoy the process of creating a firearm that is uniquely yours.
