Ruger 77/22 Centerfire

The History of Sturm, Ruger & Co.

Sturm, Ruger & Company, Inc., more commonly known as Ruger, is an American firearm manufacturing company headquartered in Southport, Connecticut. Founded in 1949 by Alexander McCormick Sturm and William B. Ruger in a rented machine shop in Connecticut, the company has since become one of the largest firearm manufacturers in the world - shadowed only by Remington and perhaps Smith & Wesson.

Ruger is widely recognized for producing firearms that span a broad spectrum of uses such as bolt-action rifles and pistols, semi-automatic rifles, single-shot rifles, shotguns, and revolvers. As recognition of its quality products grew so did the public’s interest in investing in the company’s shares. Ruger went public in 1969 and grew exponentially since then, and it is on the New York Stock Exchange (NYSE:RGR) since 1990.

In 2020, Ruger made another big move with their acquisition of Marlin Firearms from Remington Outdoor Company.

For decades now both newbie and seasoned shooters have been consistently trusting Ruger’s guns for their excellent accuracy and superior long-term performance as evidenced by its continued success over all these years.

Today, Ruger’s most popular products include the Ruger 10/22 semiautomatic rifle, the .22 rimfire semi-automatic pistol Ruger MK IV, the bolt-action Ruger American rifle, the tried and tested Ruger No.1, and, of course, the timeless Ruger Security-Six revolvers.

Ruger 77/22 Centerfire Rifle Review

Ruger 77/22 was introduced in 1984 as a rimfire version of the centerfire Ruger M77. It was initially chambered only for .22 LR, but other calibers were gradually introduced through the years. In 1995, the centerfire .22 Hornet was added to the lineup and proved widely popular. Its popularity grew to the point where other chamberings were no longer needed, so today, Ruger 77/22 is sold only in .22 Hornet.

This affected the scope mounting surface of the rifle so that the centerfire 77/22 doesn’t have one-piece scope mounts interchangeable with the rimfire 77/22. You can read our review of the Ruger 77/22 Rimfire to learn more about the rifle itself, or you can scroll down to find our scope mount recommendations for the Ruger 77/22 centerfire rifle.

Ruger 77/22 Centerfire Calibers

Ruger originally offered the Ruger 77/22 models in .22LR caliber but added the .22 WMR in the following years after the initial launch of the model. Today, Ruger 77/22 is mainly sold in the .22 Hornet caliber.

Ruger has developed its own scope mounting surface which is integral to the receiver of some of the Ruger rifles. It is unique and offers an exceptional amount of sturdiness and reliability, but the price to pay in exchange for that is that finding a proper scope mount for it can be challenging at times.
