Special Episode: The ArmaLite AR-10 (Pt.1)

In this first part of a TAB special episode examining the history of the ArmaLite AR-10 Vic discusses the early origins, history and development of the now legendary 7.62x51mm rifle. At the heart of this episode is a remastered version (certainly the best currently available online) of the c.1958 ArmaLite/Fairchild promotional film that features Eugene Stoner and shows many of the early ‘Hollywood’ Armalites in action! The first part of this special documentary concludes with Vic examining a Hollywood-made AR-10B (the last iteration of the US-made AR-10s).

Part two of the episode can be found here and includes an overview of almost every Artillerie Inrichtingen (A.I.)-made model of AR-10, including the Cuban, Sudanese and Portuguese variants. 


Armalite & the AR-10’s Early History

Much has been written about the AR-10, Eugene Stoner and the genesis of the AR-15’s parent rifle. It’s a design which owes much to many: Stoner, George Sullivan, Melvin Johnson and later the engineers at Artillerie Inrichtingen.

ArmaLite, formed by George Sullivan with the help of Richard Boutelle, President of the Fairchild Engine and Aircraft Corporation, began work on the first AR-10 prototypes in 1955. Designed by Eugene Stoner, using his patented direct gas impingement system. Stoner patented this system in 1956, with the patent being granted in September 1960 (US #2,951,424).

The AR-10 had an aluminium-alloy forged receiver, an in-line stock, polymer furniture and chrome-lined steel parts. While conventional steel barrels were the norm an ill-fated attempt to use an aluminium/steel composite barrel during US Army evaluations proved disastrous when the steel inner parted from the aluminium outer and caused the barrel to burst. As a result of these weight saving efforts the rifle weighed just ~3.4kgs/7.5lbs unloaded. The Armalite AR-10 had a side mounted gas tube, a top mounted charging handle and fed from 20-round box magazines. One of the most interesting features was the large aluminium muzzle device, fitted to some ArmaLite-made Rifles, which reduced sound and flash.

In 1957, ArmaLite sold the AR-10 manufacturing rights to the Dutch small arms manufacturer Artillerie Inrichtingen, while US manufacture was licensed by Colt in February 1959. With minimal financial returns Fairchild sold their interests in ArmaLite in 1962.

Featured in the first part of Vic’s special episode on the AR-10 is an original Armalite/Fairchild promotional film, originally filmed in 16mm, that dates from around 1958. While a version of this film has been shared online for a number of years it is grainy, washed out and of relatively low audio quality. Vic reproduced the very rare promotional sales film in the 1990s onto VHS (a process he explains in the video). He has managed to take an original VHS copy and digitally remaster it to regain some of the original’s clarity and detail.

The promotional film was originally used by salesmen to showcase the AR-10 to potential clients and features Hollywood-produced guns. Both Stoner and Charles Dorchester (ArmaLite’s production manager) are seen in the film demonstrating the AR-10. The rifle’s action, function and controls are explained and various variants, including rifle and light machine gun, are demonstrated. The demonstration segment included a sub-zero test, covering in sand and much and Stoner himself dumping 5 magazine’s through the rifle in quick succession. The promotional film concluded with demonstrations of firing rifle grenades and a belt-fed AR-10.

Vic concludes the first part of the AR-10 overview episode with an examination of an AR-10B rifle held by the Netherlands’ Nationaal Militair Museum. In the second part of the episode Vic will look at nearly a dozen AR-10 variants made by Artillerie Inrichtingen (A.I.) between 1957 and 1961.
