The Ruger 77/22 is Ruger's premium bolt-action rimfire — a Mauser-style controlled-round-feed bolt action on a 22 LR platform. The 77/22 uses the same rotary magazine concept as the 10/22 in a bolt-action package. The stainless variant provides corrosion resistance for field use. The 77/22's Mauser extractor and controlled-round-feed are unique in the 22 LR category, providing a manual of arms identical to the 77 centerfire rifles.
