Armalite AR-10: Evolution and Modernization
Armalite new version AR-10
Caliber : 7.62 × 51 mm NATO
Historical Overview
The AR-10, originally developed by Armalite in the 1950s, is a lightweight, magazine-fed rifle that chambers the 7.62 × 51 mm NATO round. Despite failing to secure a contract in the U.S. military's selection test in 1956, the design garnered interest internationally. In 1957, the Dutch Artillery Department acquired licensed production rights, leading to the manufacture of approximately 5,000 units. Early batches were sold to Burma, Nicaragua, Guatemala, and Sudan.
Early Modifications and Discontinuation
In 1959, Colt made significant modifications to the original AR-10 design, resulting in the AR-10A and AR-10B models. However, the 1960s saw a shift towards smaller caliber rifles, which led to the discontinuation of the AR-10 in favor of more modern, compact designs.
Revival and Modern Enhancements
The 1990s witnessed a resurgence in the popularity of 7.62mm precision rifles, prompting Armalite to revisit and improve the AR-10. In 1994, the company began re-engineering the rifle, with production starting in 1996 under the model designation AR-10B. This updated version incorporated several advancements and design changes to enhance performance and reliability.

AR-10B
The AR-10B tested in 1994 was very similar to the AR-15, but with two obvious differences: the 20-round 7.62mm magazine and the hook-shaped bolt handle inside the handle. Only this bolt handle is still the design of the 1960s.
