The Remington Model 700 is a series of bolt-action (later semi-automatic 74* series) centerfire rifles manufactured by Remington Arms since 1962. It is a development of the Remington 721 and 722 series of rifles, which were introduced in 1948.
For example, factory and aftermarket receivers using the Remington 700 footprint are produced with various types of action threads, all with a 26.99 mm (1 + 1 ⁄ 16 in) diameter, but with a pitch of either a 1.588 mm (16 TPI, Remington standard), 1.411 mm (18 TPI) or 1.270 mm (20 TPI, Savage standard).
The M24 SWS has the "long action" bolt version of the Remington 700 receiver but is chambered for the 7.62×51mm NATO "short action" cartridge that has an overall length of 2.750 inches (69.85 mm). The "long action" allows the rifle to be re-configured for dimensionally larger cartridges up to 3.340 inches (84.84 mm) in overall length.
Little is known of its usage or technical data, and pictures are rarely available. The pictures that have been released show a Remington 700 Long-Action receiver mated to a McMillan A2 stock. The rifle was chambered in .300 Winchester Magnum. The rifle was the most prolific sniper weapon in the Navy until the advent of the Mk 13 Mod 5.
The Remington 700 Long Action (LA) naturally has a longer distance between the front and rear screw holes, and therefore continuous scope mount assemblies for the 700 LA do not fit on the 700 SA nor the above-mentioned firearms. However, two-piece scope mounts in general interchange for the mentioned models. List of common screw patterns
The Mk 13 Mod 5 utilises the "long-action" bolt of the Remington 700/M24 receiver and has a precision barrel that can be fitted with the suppressor of the Mk 11. It has a 3-sided Modular Accessory Rail System (MARS) for mounting optics on top and Picatinny rail accessories on each side, and a folding bipod. [10]
The first known use of bipods on firearms can be traced back to hand cannons of the 12th century, which were cast iron barrels laid on top of short poles. [2]Bipods on rifles are first known to have been used in an improvised fashion during the mid-19th century, particularly by frontiersmen hunting American bison and other wild animals.
The round receiver can be produced on a lathe rather than requiring a mill. The recoil lug was a simple plate of steel sandwiched between the barrel and receiver [2] (like on Savage Model 1920, but even simpler). Remington advertised the rifle as having the "strongest bolt action ever developed." [3] with a new encased bolt head. The bolt was ...
