What Is a Good AR15 Upper Receiver?
The best AR15 Upper Receiver for you depends on your needs and preferences. However, here are some things to look for while browsing:
-
Material: AR Uppers are typically made from aluminum or polymer. Aluminum is more durable, but also heavier. Polymer is lightweight, but may not be as durable.
-
Barrel: The barrel is the most important component of an AR15 upper. The barrel length and caliber are the primary factors that determine how your AR15 is best used, so pick an upper that is designed for your specific needs.
-
Bolt carrier group: The bolt carrier group, or BCG, is the part of the upper receiver that houses the bolt, which is responsible for loading and firing the rounds. Look for a high-quality bolt carrier group that is properly staked and has a chrome-lined interior.
-
Charging handle: The charging handle is used to charge the rifle and make it ready to fire. Look for a charging handle that is easy to grip and operate.
-
Gas system: Gas systems move the hot gas from the fired round away from the chamber, helping reduce recoil and chamber the next round. It is important to match the gas system to the intended use of the rifle.
-
Compatibility: Make sure the upper receiver is compatible with the lower receiver and other components of the rifle.
Can You Still Buy AR15 Uppers?
Yes, buying an upper receiver for an AR15 does not require an FFL (Federal Firearms License), so you can legally purchase it online. This goes for AR pistol uppers, complete upper receivers, and stripped AR uppers. Of course, always refer to your local and state laws, as some areas may not allow such purchases.
Is It Cheaper to Buy or Build an AR Upper?
Whether it is cheaper to buy or build an AR15 Upper Receiver depends on several factors, such as the cost of the individual components and the level of expertise required to assemble them.
Building an AR15 upper from scratch can be more cost-effective than buying an AR15 complete upper, especially if you already have some of the necessary tools and equipment. Additionally, you have the flexibility to select individual components and customize the rifle to suit your specific needs and preferences.
On the other hand, buying complete upper receivers is more convenient and may save time, especially if you do not have the necessary tools and expertise to assemble the components yourself. However, an AR15 complete upper can be more expensive and may not offer the same level of customization as a build from scratch.
Generally, if you want a specific setup or caliber not commonly found on commercial receivers, building your own is the way to go if you have the knowledge or willingness to learn. If not, it is more cost-effective to buy an AR15 complete upper receiver. Also, note that purchasing quality upper parts could be more expensive than using lower quality parts, but it will affect the accuracy and durability of your rifle in the long run.
