DPMS AR-10: A Closer Look at the Platform
DPMS AR-10 rifles have a history marked by both praise and criticism. While some models have earned a solid reputation for reliability and accuracy, others have faced challenges regarding consistency and longevity. This review will focus on assessing the overall performance and identifying key aspects to consider before purchasing a DPMS AR-10. Understanding the specific model you're considering is crucial, as variations exist within DPMS's AR-10 lineup.
Key Features and Specifications
The core features of a typical DPMS AR-10 include:
- Caliber: .308 Winchester (7.62x51mm NATO) – This powerful cartridge provides significant stopping power and longer effective range compared to the 5.56x45mm used in AR-15s.
- Gas System: Generally a long-stroke piston system or direct impingement, impacting reliability and maintenance. Direct impingement is less expensive but requires more cleaning, while piston systems are cleaner but more complex.
- Receiver Material: Usually forged aluminum, offering a balance of strength and weight. High-quality receivers are crucial for accuracy and longevity.
- Barrel Length: Varies depending on the model, with common options including 16”, 18”, and 20” barrels. Longer barrels generally offer increased accuracy and velocity.
- Operating System: As mentioned above, direct impingement or piston systems. Consider the advantages and disadvantages of each when making your choice.
- Weight: Heavier than AR-15s due to the larger cartridge and robust construction, affecting maneuverability.

Performance and Accuracy
The accuracy of a DPMS AR-10 varies significantly depending on the specific model and barrel quality. Higher-end models with premium barrels generally deliver excellent accuracy, capable of sub-MOA (minute of angle) performance with high-quality ammunition. However, budget-friendly models may exhibit greater variations in accuracy.
Case Study: A user review on a popular firearms forum reported achieving 1.5 MOA accuracy with a DPMS AR-10 with a 20" barrel using factory ammunition. Another reported significantly more variance, indicating the importance of quality control in manufacturing.
This highlights a potential drawback: consistency. While capable of high accuracy, not all DPMS AR-10s reach this potential. Thorough inspection and testing are recommended before committing to a purchase.
Reliability and Durability
Reliability is another area where DPMS AR-10s show some variation. Some users have reported issues with malfunctions, particularly with certain ammunition types or due to manufacturing imperfections. Others find them highly reliable under diverse conditions. Proper maintenance, high-quality ammunition, and careful cleaning are vital for maintaining reliability. A well-maintained DPMS AR-10 can prove highly reliable.
