Ruger’s flagship bolt action rifle is the Model 77, also known as the Hawkeye. From the beginning, the Hawkeye was designed to be a more modernized version of the Mauser rifle. It basically utilizes the same Mauser action, only with investment casting instead of the forged receiver of the original Mauser, and with a simpler ejector. Two of the more notable versions of the Model 77 today are the Guide Gun, designed to fire larger calibers, and the Gunsite Scout, which is a carbine version with a detachable box magazine.
