Technology Way Ahead of Its Time. ArmaLite has been in the business of developing and producing weapons for the commercial and military markets since the 1950's. Although the company is no longer a division of Fairchild Aviation and has since moved to Illinois, while working at ArmaLite, chief engineer Eugene Stoner invented a weapons platform that would evolve into a family of exceptional rifles. One of his later designs -- the U.S. M-16 -- would enter military service in 1962 where it remains today as this nation's primary battle rifle some 52- years later. This makes the AR- series the longest running modern military rifle in American history.

In 1955, Stoner completed work on the revolutionary AR-10 rifle. Despite the fact it was smaller, lighter and easier to fire than any competing design, the mighty M1's heir apparent was destined to be the M-14, and the military contract was therefore awarded to Springfield Armory. At the heart of the ArmaLite AR-10 lies a unique engineering design that would forever change the landscape of military small arms manufacturing. Unlike anything that came before, the AR-10's bolt locks into a steel extension on the barrel, not the receiver.

This advancement paved the way for the use of aluminum receivers that would substantially lighten the rifle without sacrificing structural integrity. Instead of heavier wood furniture, the stocks were being constructed from advanced materials like space age polymers. It therefore became possible to reduce the weight of this service rifle by some 40%, thus allowing a soldier to carry more ammo into the field during extended combat operations.

The aircraft grade forgings of the ArmaLite Defensive Sporting Rifle AR-10 A4 have no die cast or extruded parts in the receivers. Hard coat anodized and dry film lubed per military spec, the aluminum surfaces are corrosion and wear resistant. The gun weighs in at 7.9 lbs, placing it somewhere between a comparable AR-15 and M1A rifle.

For those familiar with the AR-15 platform, the AR-10's stock return spring and buffer are essentially the same. Moreover, both rifles position the gas tube above the barrel, which terminate in the upper receiver and then connect to the gas key on the bolt carrier group.

This system of operation is commonly referred to as "direct impingement" (DI), which has several advantages over gas piston rifles. For semi- automatic rifles with barrel lengths of 16" or greater, DI is more accurate, lighter weight, far easier to free float the barrel and much less expensive to manufacture.

For additional comparison, the AR-10 shares the same charging handle placement as the AR-15 and functions identically. The takedown pin, pivot pin, safety, bolt catch release button and magazine release button are also in familiar places and accomplish the exact same functions. However, the AR-10's bolt is different. In addition to being massive for handling a more powerful cartridge, the AR-10 bolt requires three gas rings instead of only one on the AR-15. Another noticeable difference is the firing pin, which has been spring loaded.

The 16" chrome lined barrel is constructed of 4140 chrome moly steel that has been double lapped for greater accuracy. The 1:11.25" twist rate optimizes bullet weights between 150gr to 175gr. Thanks to its longer effective operating range and superior stopping power, the .308 caliber AR-10 has numerous advantages over its small bore counterparts.

Compared to the 55gr to 75gr bullet options on the 5.56, the 150gr to 175gr projectiles of the 7.62 cartridge deliver almost triple the energy in ft/lbs at 300 yards. This means cleaner kills and longer effective range shots on game animals -- while recoil remains controllable. Even though the weight increase of the AR-10 platform is noticeable, it is far from being cumbersome.
The excellent tactical 2- stage trigger breaks cleanly and evenly for enhanced shot placement.

ArmaLite lists minute-of-angle accuracy for the AR-10 A4 between 2" to 2.5", which is certainly impressive considering the average bolt action carbine would be hard pressed to do this on a good day. Items not included are iron sights or a carry handle. However, the front gas block has a Picatinny rail, so front and rear detachable sights can easily be added if the shooter so desires.

This model AR-10 accepts Stoner / DPMS pattern magazines and one Magpul 20- round Pmag is included. In case a round fails to go in battery while feeding, the rifle possesses a forward assist, while a receiver dust cover prevents potential dirt and debris from entering the action during transport. A 6- position collapsible buttstock provides allows the shooter to easily adjust length of pull, while the A2 grip and mid- length handguard provide steady handling.

All steel parts wear a mil-spec manganese phosphate finish. The build quality is 100% with a super tight fit between the upper and lower receiver. The M4 style feed ramp, which is a smooth transitional cut into the lower receiver and barrel extension, further enhances feeding and reliability. The rifle is backed by a limited lifetime warranty.

Overall, the ArmaLite AR-10A4 is an excellent choice for anyone looking to buy a hard hitting .30 caliber, semi- automatic rifle capable of taking medium to big game.
