Buyer’s Guide

The Ar Stoner Upper is a popular firearm component that combines precision engineering with modular versatility. Understanding the key features and considerations will help you select the right upper receiver for your AR-15 build.

Material Quality and Construction

Invest in aerospace-grade 7075-T6 aluminum for superior strength-to-weight ratio and durability. Mil-Spec electroless nickel or hardcoat anodizing provides long-term corrosion resistance and scratch protection.

Modular Design Compatibility

Ensure the upper receiver’s keyway accepts standard magazines and accessories. Some designs incorporate Picatinny rails, flush-fit handguards, or directimpingement systems that affect overall length and weight.

Operating Systems

Direct impingement systems cool gas through the bolt carrier, while gas block systems redirect gas to the side. Direct impingement requires shorter barrels and different buffer tube lengths.

Performance Considerations

Higher gas port pressures provide faster cycling but increase recoil. Lower pressures reduce felt recoil but may affect cyclic rate. Proper gas tuning ensures consistent operation across different ammunition types.

FAQ

What exactly is an Ar Stoner upper?

Ar Stoner upper receivers are a specific type of component in a semi-automatic rifle. Unlike traditional receiver designs, these upper receivers incorporate several innovative engineering features that enhance stability, accuracy, and durability under rapid fire conditions.

The primary innovation is the integration of a forward assist mechanism into the upper receiver itself, eliminating the need for a separate forearm assembly. This design also features a more aggressive gas port design to prevent fouling and maintain consistent performance during extended use.

How does the Ar Stoner upper compare to other receiver designs?

Compared to traditional AR-15 upper receivers, the Ar Stoner design offers superior handling characteristics due to its forward assist mechanism and improved gas system. However, it may be more expensive and less readily available, so builders need to weigh these factors against their specific requirements.

For bolt carrier groups from other manufacturers, Ar Stoner receivers typically offer better integration and reduced potential for alignment issues during assembly.

What are the key benefits of Ar Stoner receivers?

The most significant benefits include enhanced structural integrity through optimized material placement, improved gas system efficiency that reduces cleaning requirements, and a more straightforward design that simplifies mounting accessories.

Users report increased reliability in harsh environments and extended magazine capacities due to space efficiencies in the receiver design.

Which manufacturers produce Ar Stoner upper receivers?

Original Ar Stoner receivers were made by Rock River Arms and Wilson Combat. However, the design specifications have since been licensed to several other manufacturers, including Black Hills Arsenal and Colt’s Manufacturing Company.

These manufacturers produce both standalone upper receivers and complete uppers with a variety of options for barrel, bolt carrier group, and other components.

What maintenance is required for Ar Stoner receivers?

Standard AR-15 maintenance applies, primarily focusing on cleaning the bolt carrier group and gas system. The unique gas port design reduces debris accumulation but still requires regular cleaning to maintain optimal performance.

Check the forward assist mechanism periodically for proper operation and ensure all internal components, including the gas key and piston system, remain properly lubricated.

Can Ar Stoner receivers be modified or customized?

Like any AR-15 upper receiver, Ar Stoner parts can be exchanged for different manufacturers’ components to create hybrid builds. This includes switching bolt carrier groups, installing different gas systems, or incorporating accessories from other manufacturers.

However, any alterations must maintain the original design’s critical dimensions to preserve functionality and compatibility with Ar Stoner-specific features like the forward assist mechanism.
