The Model 1922 Springfield rifle was as near perfect as could be asked for. It was accurate and pleasant to shoot, it had a smooth action, and it was sturdy and reliable. It also perfectly mimicked the size, weight, look, and handling qualities if the 1903 service weapon. There were several improved versions of the rifle produced, until the Second World War made the production of .22 rifles an impractical use of production materials and facilities. The U.S. military never produced another .22 rimfire, after the end of the Second World War. A number of commercial rifles, in .22 rimfire, were acquired, but even this ended after the adoption of the M-16. The M-16 adapts very easily to the firing of .22 rimfires. No barrel sleeve is needed, since the M-16 already fires .22 projectiles, though quite different from the rimfire versions. A number of devices were made by several different companies, though even these were little used. Along with a change in weapons, there was a shift in emphasis. Marksmanship, though still highly regarded in an infantryman, is no longer considered to ba a vital component of the modern battlefield.
