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

Design and features

From the beginning, the Ruger 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.

Perhaps the most novel feature of the M77 is the only one that has not been redesigned, the angled action screw. The front action screw of traditional bolt-action rifles draws the receiver directly down against the stock. The M77 uses an angled screw that draws the action down and to the rear, tightly bedding it against the stock.

Variants

The M77 has undergone one minor and two major redesigns. The first change involved incorporating a proprietary scope mount milled integral with the receiver. The first rifles had simple rounded-top receivers drilled and tapped for separate scope mounts.

M77 Mark II

<!– Deleted image removed:

–> The M77 was retooled almost entirely and reintroduced in 1991 as the Mark II. The safety, bolt, and trigger were completely redesigned. The claw extractor was retained, but the bolt face was opened up to allow controlled-round feeding. The plunger ejector was replaced with a Mauser style blade ejector. Finally, a three-position safety allowed the bolt to be operated while the gun was still on safe, making unloading of the rifle less hazardous. Ruger also eliminated the adjustable trigger that came stock on the original M77.

Hawkeye

In 2006, Ruger introduced new features and a new name for their rifle, the Hawkeye. Major changes were made to the trigger system and the stock was recontoured, but otherwise the rifle remained unchanged.

The LC6 trigger addressed complaints from consumers that the Mark II trigger, though safer than the earlier one, was poorly designed for accurate shooting.

The LC6 trigger is lighter and smoother. Despite the listed improvements of the LC-6 trigger there still seems to be nagging complaints about it.

30.06 Cal SAR (Search and Rescue) Rifle

The SAR Rifle, .30-06 calibre, RUGER, Model M77 is a rifle designed for use by Canada's Search and Rescue Technicians (SAR Techs) and Aircrews. The SAR Rifle is designed to be a compact survival rifle chambered in .30-06 Springfield. The rifle is based on the standard Ruger M77 Mk II rifle but the barrel has been shortened to 14.5“. The orange coloured buttstock has been modified so that it can fold along the left hand side of the stock and it also can hold 6 additional rounds of ammunition. The rifle is issued with a special case that has been designed to attach to the Search and Rescue Technicians parachute harness.<ref>30.06 Cal SAR (Search and Rescue) Rifle</ref><ref>World Infantry Weapons: Canada</ref>

Working closely with Gunsite Training Center in the development of the rifle and thus meeting the criteria of the modern scout rifle set forth by Jeff Cooper. The rifle is chambered in .308 Winchester and weighs

and sports a 16.5” barrel and black laminate stock. It features ghost-ring iron sights, flash hider and a picatinny rail for optics mounting. It takes 5- or 10- round box magazines.
