Are you looking to build the ultimate AR-15? If so, you’ll need to make sure you’re choosing the right AR-15 parts. From the upper and lower receiver, to the bolt carrier group, each component needs to be chosen with the utmost care in order to ensure the highest quality and most reliable build. In this guide, we’ll go over all the important factors to consider when selecting your AR-15 parts, so you can get the best bang for your buck.

Barrel         

When it comes to building an unbeatable AR-15, one of the most critical components you’ll need to consider is the barrel. The right barrel can mean the difference between accurate, consistent shots and missed opportunities. At 80-lower.com, we offer a variety of high-quality ar 15 parts, including barrels designed to meet your needs.

When choosing a barrel, there are several factors to consider, including length, twist rate, and material. For most applications, a 16-inch barrel with a 1:8 twist rate is a good starting point. This length provides a good balance of accuracy and maneuverability, while the twist rate helps stabilize a wide range of bullet weights.

Material is also an important consideration. Stainless steel is a popular choice due to its corrosion resistance and durability, while chrome molybdenum offers excellent strength and is a cost-effective option. Whatever material you choose, make sure it’s from a reputable manufacturer to ensure quality and consistency.

At 80-lower.com, we carry barrels from top manufacturers such as Aero Precision and Ballistic Advantage, ensuring you have access to the best AR-15 parts available. We also offer a variety of lengths, twists, and materials to meet your specific needs and preferences.

When building an AR-15, the barrel is one component you don’t want to skimp on. Invest in a high-quality barrel from a trusted source like 80-lower.com to ensure your rifle performs at its best every time you pull the trigger.

Bolt Carrier Group

The bolt carrier group (BCG) is an essential part of your AR-15. It is responsible for cycling rounds and extracting spent casings, which makes it one of the most important parts to get right. Quality and reliability are key factors when selecting a BCG, as a failure can be catastrophic and may even result in injury.

First, let’s start with the material. The most common materials used for BCGs are steel and titanium. Steel is durable and has a long lifespan, while titanium is lightweight and has excellent corrosion resistance. Each material has its pros and cons, so consider what matters most to you.

Next, look for coatings that improve the BCG’s durability, reliability, and performance. Nickel boron and chrome are popular coatings that reduce friction and wear. They also provide resistance to corrosion and fouling.

Another important factor is the design. The weight, length, and shape of the BCG can all affect performance and reliability. Lighter weight BCGs may result in less recoil and better accuracy, while heavier BCGs may provide greater reliability. Ultimately, it’s up to you to decide what design fits your shooting style and preferences.

Finally, be mindful of the brand and quality of the BCG you choose. There are many reputable manufacturers out there, so do your research and read reviews from other gun owners to get a sense of which brands and models are the best.

When it comes to choosing a BCG for your AR-15, invest in a quality, reliable, and well-designed product. This will ensure your gun functions properly and safely, and that you get the most bang for your buck.
