H&R A2 Government Carbine: A Comprehensive Guide for Enthusiasts

The H&R A2 Government Carbine represents a significant piece of American firearms history, embodying a specific configuration of the AR-15 platform widely adopted by law enforcement and civilian shooters alike. If you’re looking to understand the nuances of this iconic carbine, its features, its place in the AR-15 landscape, and its modern-day relevance, you’ve come to the right place. This comprehensive guide delves deep into every aspect of the H&R A2 Government Carbine, providing the knowledge you need, whether you’re a seasoned collector or a newcomer to the world of AR-15 rifles.

Unpacking the H&R A2 Government Carbine: Definition and Evolution

The term “H&R A2 Government Carbine” refers to a specific type of AR-15 carbine manufactured by Harrington & Richardson (H&R) and built to closely resemble the M16A2 service rifle configuration. The “A2” designation indicates specific upgrades over the original M16/AR-15 design, including a redesigned rear sight adjustable for both windage and elevation, a heavier barrel profile for improved accuracy, and a case deflector. The “Government Carbine” aspect signifies its intended use, mirroring the rifles used by the US military and law enforcement.

H&R’s involvement in AR-15 production stems from their history as a major military contractor. While Colt initially held the primary contract for M16 production, other manufacturers like H&R were brought on board to meet the escalating demand during the Vietnam War era and subsequent conflicts. The H&R A2 Government Carbine, while not identical to military-issue rifles, offered a close approximation for civilian and law enforcement markets, providing a reliable and familiar platform.

The AR-15 platform itself has undergone significant evolution. From its initial design as a lightweight rifle chambered in 5.56mm NATO, it has branched into countless variations, calibers, and configurations. The A2 variant was a key step, addressing some of the early shortcomings of the original M16. Today, the H&R A2 Government Carbine represents a classic configuration, appreciated for its simplicity, reliability, and historical significance. Its design principles continue to influence modern AR-15 designs.

Core Components and Operation of the A2 Carbine

At its core, the H&R A2 Government Carbine operates on a direct impingement gas system, a design pioneered by Eugene Stoner. This system utilizes gas tapped from the barrel to cycle the action, ejecting spent cartridges and loading a fresh round. The key components include:

Upper Receiver: Houses the bolt carrier group, charging handle, and barrel.
Lower Receiver: Contains the fire control group (trigger, hammer, sear), magazine well, and buttstock.
Bolt Carrier Group (BCG): The heart of the action, responsible for extracting, ejecting, and loading cartridges.
Barrel: Typically a 16-inch barrel with a 1:7 or 1:9 twist rate, optimized for stabilizing 5.56mm ammunition.
Handguards: Polymer handguards protect the shooter’s hands from the heat of the barrel. The A2 typically utilizes round, ribbed handguards.
A2 Front Sight Base: Incorporates the front sight post and bayonet lug.
A2 Rear Sight Assembly: Adjustable for windage and elevation, allowing for precise zeroing.

Understanding the function of each component is crucial for maintaining and troubleshooting the rifle. The direct impingement system, while effective, requires regular cleaning to prevent carbon buildup, which can lead to malfunctions.

The Enduring Relevance of the A2 Carbine

Despite the proliferation of modern AR-15 variants with advanced features like free-floating handguards and adjustable stocks, the H&R A2 Government Carbine retains significant relevance. Its simplicity and reliability make it an excellent choice for:

Entry-Level Shooters: The A2’s straightforward design is easy to learn and operate.
Collectors: The H&R A2 represents a piece of AR-15 history and is sought after by collectors.
Budget-Conscious Shooters: A2-style carbines are often more affordable than their modern counterparts.
Those Seeking Reliability: The A2’s proven design is known for its reliability in adverse conditions.

Furthermore, the A2 configuration serves as a foundation for many modern AR-15 builds. Its core components and operating principles remain largely unchanged, making it a valuable learning tool for anyone interested in understanding the AR-15 platform.

Delving into DPMS: A Key Player in AR-15 Components

While H&R produced complete rifles, it’s important to acknowledge the role of companies like DPMS (Defense Procurement Manufacturing Services) in the AR-15 ecosystem. DPMS, now owned by Remington Outdoor Company, was a major manufacturer of AR-15 parts and components, including those used in A2-style builds. They supplied parts to numerous manufacturers and builders, contributing significantly to the availability and affordability of AR-15 rifles.

DPMS’s contribution extended beyond simply manufacturing parts. They also played a role in standardizing AR-15 components, ensuring compatibility between different manufacturers. This standardization made it easier for consumers to build and customize their own AR-15 rifles, further popularizing the platform.

While DPMS no longer operates independently, their legacy continues to influence the AR-15 market. Many of their designs and manufacturing processes are still in use today, ensuring the continued availability of high-quality AR-15 parts and components.
