When it comes to building a custom firearm, the DPMS AR-10 upper parts are a popular choice among enthusiasts. These components offer a blend of quality, reliability, and customization options that make them a favorite among shooters. In this article, we will delve into the various aspects of DPMS AR-10 upper parts, providing you with a detailed overview to help you make an informed decision.
Understanding the DPMS AR-10 Upper Receiver
The DPMS AR-10 upper receiver is the heart of your firearm. It is the part that houses the barrel, bolt carrier group, and other internal components. The upper receiver is available in two types: mil-spec and commercial. The mil-spec receiver is made from 7075-T6 aluminum and features a matte black finish, while the commercial receiver is made from 6061-T6 aluminum and comes in various finishes, including black, flat dark earth, and olive drab.
| Upper Receiver Type | Material | Finish |
|---|---|---|
| Mil-Spec | 7075-T6 aluminum | Matte black |
| Commercial | 6061-T6 aluminum | Black, flat dark earth, olive drab |
Choosing the Right Barrel
The barrel is one of the most critical components of your DPMS AR-10 upper. It determines the bullet’s velocity, accuracy, and barrel life. When selecting a barrel, consider the following factors:
- Length: Barrels come in various lengths, such as 16″, 18″, and 20″. The longer the barrel, the higher the velocity and accuracy, but also the heavier the firearm.
- Material: Barrels are typically made from stainless steel or chrome-molybdenum (Chrome-Moly). Stainless steel barrels are corrosion-resistant and have a longer lifespan, while Chrome-Moly barrels are known for their durability and accuracy.
- Profile: The barrel profile affects the weight and balance of the firearm. A lightweight profile will reduce the overall weight but may sacrifice some accuracy and durability.
Optimizing the Gas System
The gas system is responsible for cycling the firearm’s action. It is crucial to choose the right gas system for your DPMS AR-10 upper to ensure reliable operation. Here are the three main types of gas systems:
- Full-Auto: This system is designed for full-auto firearms and requires a full-auto lower receiver. It is not suitable for semi-auto firearms.
- Carbine: The carbine gas system is designed for shorter barrels and is suitable for both semi-auto and full-auto firearms. It provides a balance between performance and reliability.
- Mid-Length: The mid-length gas system is a popular choice for shooters looking for a balance between performance and weight. It is suitable for both semi-auto and full-auto firearms and is known for its reliability and accuracy.
Customizing Your DPMS AR-10 Upper
One of the advantages of building a custom firearm is the ability to personalize it. Here are some popular customization options for your DPMS AR-10 upper:
- Handguards: Handguards provide a secure grip and protect the barrel from heat. There are various handguard options available, including M-LOK, KeyMod, and Picatinny rails.
- Barrel Nut: A custom barrel nut can improve the fit and finish of your barrel. It also allows for easier barrel installation and removal.
- Chamber and Bolt Face: Upgrading your chamber and bolt face can improve accuracy and reliability. This is especially beneficial for shooters who use high-performance ammunition.
