Introduction

The Adaptive combat rifle is an autoloading rifle that fires a single cartridge with each pull of the trigger and uses part of the fired cartridge’s energy to eject the case and load another cartridge into the chamber. In contrast, a bolt-action rifle requires the user to cycle the bolt manually before they can fire a second time, and a fully automatic rifle fires continuously until the trigger is released.

In 1883 Hiram Maxim patented in Britain a recoil-operated conversion of a Winchester rifle. In 1884 another recoil-operated semi-automatic rifle was patented by the American Horace Updegraff. Another one of the first designs of a recoil-operated semi-automatic rifle is attributed to Ferdinand Mannlicher, who unveiled the design in 1885 based on work begun in 1883. Other non-gas operated semi-automatic models were the Model 85 and Mannlicher Models 91, 93 and 95 rifles. The designs were deeply flawed and never made past the conceptual/prototype stage due to issues inherent to the black powder used in their cartridges (based around the Austrian 11×58mmR M/77), such as insufficient velocity and excessive fouling; automatic firearms would only become feasible after smokeless powder became widespread. Mannlicher’s designs were, nonetheless, the forerunners of automatic rifles and served as a base for a number of future weapons, such as Browning machine guns (M1917, M1919, and M2) and the Lewis gun. Furthermore, from the early 1890s up until his death in 1904, Mannlicher produced smokeless powder versions of his guns.

In 1903 and 1905, the Winchester Repeating Arms Company introduced the first low-power blowback (non-gas operated) semi-automatic rimfire and centerfire rifles. The Winchester Model 1903 and Winchester Model 1905 operated on the principle of blowback to function semi-automatically. Designed by T.C. Johnson, the Model 1903 achieved commercial success and continued to be manufactured until 1932, when the Winchester Model 63 replaced it.

By the early 20th century, several manufacturers had introduced semi-automatic rifles, including Winchester, Remington, Fabrique Nationale, and Savage Arms, all using the direct blowback system of operation. Winchester introduced a .351 Winchester Self-Loading semi-automatic rifle, the Model 1907, as an upgrade to the Model 1905, utilizing a blowback system of operation, offering more power than its counterpart. Both the Model 1905 and Model 1907 saw limited military and police use.
