Source-derived summary

The Ruger M77 is a bolt-action rifle produced by Sturm, Ruger & Co. It was designed by Jim Sullivan during his three years with Ruger. It was designed primarily as a hunting rifle featuring a traditional Mauser K98-style two-lugged bolt with a claw extractor.

History

Ruger's first bolt action rifle was introduced to the U.S. market back in 1968 after some years of design and innovation led by Jim Sullivan and influenced Bill Ruger himself, who hired Sullivan in 1965 primarily to develop the rifle.

Investment casting was used to save on costs. The M77's popularity rose fast due to features such as the Mauser type claw extractor that filled a gap in the market that occurred in 1964 when Winchester discontinued the controlled round feed version of the Model 70 in order to compete with the recently introduced Remington 700, as well as for the writings of the late Jack O'Connor favoring the rifle.

Design and features

From the beginning, the M77 was intended as a modernized Mauser 98, though numerous changes were made. Bill Ruger wanted to use investment casting in place of a forged receiver. The Sullivan-designed bolt dispensed with the Mauser blade type ejector and instead used the simpler plunger style of ejector. A two-position tang safety and redesigned trigger system were also designed from scratch, while the stock design was carried out with the aid of the famous stock designer Lenard Brownell.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 26, 2026.

Critical limits

The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
