The Ruger Model 77 (also known as the M77 series) is a bolt-action rifle platform developed by Ruger for sporting and recreational shooting applications. First introduced in 1968, the Model 77 has been offered in multiple generations and configurations, making it one of Ruger’s long-running centerfire rifle platforms.

The rifle operates using a manual bolt-action system, and over its production history the series has included variations in feeding systems, safety arrangements, stock styles, and action design. Many later Model 77 configurations are associated with controlled-round feed operation, a design approach intended to guide cartridge feeding throughout the cycling process.

Current 77-series configurations are commonly described by the manufacturer as featuring a cold hammer-forged barrel, integral scope mounting surfaces machined into the receiver, and a three-position safety system that allows different handling positions while engaged. Some models also use a detachable rotary magazine design that sits flush with the stock profile. Feature availability can vary depending on the exact model and production period.

Across the Model 77 family, stock materials, barrel lengths, finishes, and chamberings differ substantially. Variants have been configured for different sporting preferences, including lighter carry-oriented setups and more traditional wood-stock configurations.

The Ruger Model 77 platform is commonly used for target shooting, recreational range use, and lawful hunting where permitted by local regulations. Before evaluating a specific version, it is important to confirm caliber, barrel length, weight, magazine configuration, and optics compatibility for that exact model.
