The original M40 was a military type-classified version of the Remington 700; it was factory-made, and had a one-piece wooden stock. [1] The M40A1 and A3 switched to fiberglass stocks made by McMillan, with new scopes. [1] [4] The trigger pull on both models (M40A1/A3) is 3 to 5 lb (1.4–2.3 kg). [1]
An improved version with a fiberglass stock was designated the M21 in 1972. The M21 remained the Army's primary sniper rifle until 1988, when it was replaced by the M24 sniper weapon system; some M21s were later re-issued and used in the Iraq War. [12] [3]
The rifle is fed from detachable box magazines, holding 5 rounds each. The stock is made from fiberglass, and is designed to be used from a bipod only. The buttstock is adjustable for length of pull with rubber spacers, and can be removed for compact storage. The rifle has no open sights; it can be used with a variety of telescopic or night sights.
Alternatives include using a stock made from composite materials which do not deform as much under temperature or humidity changes, or a wooden stock with a fiberglass contact area ("glass bedding"). Stocks which contact the barrel are still popular for many utility weapons, though most precision rifle designs have adopted free-floating barrels.
The stock is made from a fiberglass-reinforced phenolic composite with a core of rigid plastic foam. The handguards and pistol grip are also fiberglass reinforced plastic. Fairchild was an aircraft manufacturer, and the use of plastics, titanium, and aluminum were common in the aircraft industry at the time, though not generally used in firearms.
