Although its action is based on the revered Mauser ’98 design, there were several significant differences and distinct improvements, but other changes were controversial. Find parts for your Hawkeye, M77 Mark II, SAR, Scout and other Ruger 77.Introduced in 1968, the Ruger M77 was designed primarily as a hunting rifle.After years of engineering, testing and obtaining patents, the Ruger M77 was formally announced in 1968. Metal finish - polished and blued Stock - satin finished black walnut with rubber butt pad Sights - none (supplied with Ruger scope rings) Barrel length - 22' (most standard calibers), 24' (most magnum calibers) Overall length - 42' to 44.5' (depending on barrel and action length)Upgrade your Ruger 77 bolt action rifle with quality OEM & aftermarket small.

Other options include the Ruger M77 tang safety stock for sale. Affordable Ruger M77 Zytel stocks for sale provide a premium Zytel nylon coating for protection. Its design and appearance were refreshing to many riflemen as the initial production run quickly sold out, and over the next 22 years more than 1,000,000 rifles were produced, which is impressive by any standard.Ruger 77 hunting rifle stock options. However, the Ruger bolt action was conservative and usually featured a straight-grained, American walnut stock in classic configuration with a simple, yet attractive checkering pattern.ADTAC RM4 10/22 Rifle Stock by TacStar Adaptive Tactical. 149.00 (74) Select Options.

However, Sullivan is generally credited for being the actual designer. 1 rifle, but his first real assignment was to develop a bolt-action rifle to compete directly with the Winchester Model 70 and Remington Model 700, with the two 7s of those models eventually becoming “77” in the M77 nomenclature.Ruger outlined his ideas of what the new rifle should be and had continual influence in its design features throughout its research and development period. He arrived at Ruger in time to help with the final engineering touches to the No. Sullivan had worked for Gene Stoner at Armalite and played a major role in the development of the M16 rifle and other firearm designs. In 1965 by personal invitation from Bill Ruger.
However, testing revealed that bolts machined from bar stock featured a lengthwise grain structure that set them up with a natural fracture point when put under extreme stress, whereas cast bolts feature a rearranged grain structure that proved much stronger. Industry “experts” warned that a cast bolt would not last and that it must be machined from solid bar stock steel. For example, from the beginning it was planned to be manufactured using investment castings for the receiver and bolt. Ruger also came up with the idea for a slanted front guard screw designed to pull the action down and to the rear when tightened.Sullivan’s experiments during the development of the M77 are revealing. Also requested were a hinged floorplate and a flange to the left side of the bolt sleeve to protect shooters from gases in the unlikely event of a ruptured case. He also wanted a shotgun-style tang safety that locked the bolt when in the “on” position, which was changed on later production rifles to allow the bolt to be lifted with the safety in the “on” position for improved safety. Cruzer glide 16gb formatThe bolt is fitted with a plunger ejector, however, and the bolt face is countersunk with approximately half the circle measuring around. The bolt stop is similar in shape and size to the Mauser ’98, but it is simpler, strong and features a unique buffer that serves to absorb shock.Similar to the Mauser ’98, the M77 features a full-length, non-rotating claw extractor. Ruger and had a unique swept S-shape that was soon changed to a more conventional design with a round bolt handle.A bolt guide (anti-bind lug) was dovetailed into the bolt, but that was soon changed to be machined as a part of the bolt body that, along with other design features, resulted in smooth operation. Early M77s were fitted with a flat bolt handle at the request of Mr. Remarkably, the cast Ruger bolt proved strongest of all.Early M77 rifles featured a nearly S-shaped, flat bolt handle (bottom) while later rifles were fitted with a more traditional swept handle and round knob.The bolt is a one-piece design (for greater strength) with an integrated bolt handle that results in it being nearly impossible to break off, and it also serves as a third locking lug. After firing and extracting the case, the plunger ejector kicks the case out the ejection port as soon as the case mouth clears the receiver ring.All M77 rifles featured a sliding tang safety that locked the bolt handle down when set on “safe.” By the early 1980s the design was changed to allow the bolt handle to be lifted when the safety is in the “on” position.Ruger’s remarkable casting technology results in the receiver weighing a mere 20 ounces in billet form, which only requires around 3.7 ounces of steel to be machined off to reach its final form. Rather, as the cartridge is stripped from the magazine, it stays in front of the extractor until it is chambered, at which point the beveled extractor snaps over the cartridge rim when the bolt closes. This is a rather unique arrangement as it is not a controlled-round feed system. Computer cpu historyThe resulting profile is attractive to many people, this writer included, but it should be pointed out that this is more of a personal taste. For example, the sides are flat, as is the bottom. This manufacturing process substantially reduces production costs and allows Ruger to offer rifles at an attractive price.The Ruger receiver has a rather distinguished shape. Some shooters feel that it fails to adequately secure the action in the stock while others are quick to point out that it prevents popular aluminum pillar bedding that normally surrounds the guard screws. The simple trigger was adjustable for pull and after-travel.The recoil lug is rather conservative in size and is often criticized. While this locking system was okay, it had a tendency to be rather loose, and in rough conditions the aluminum trigger guard could be broken. The floorplate is hinged, and the release is located inside the trigger guard. The one-piece firing pin is robust, has a mass of 1.784 ounces and is encompassed in a coil mainspring that results in a lock time of 3.5 milliseconds. It is true that the flat-bottom receiver combined with the 62-degree angle guard screw that mounts directly into the recoil lug is not a common or popular choice among precision rifle builders, but in sporter-weight field rifles it can produce excellent accuracy.The Ruger M77 was offered in both (top) long- and (bottom) short-action lengths.Many Ruger M77s (of all three generations and in many calibers) are in my personal hunting rifle collection. The walnut used by Ruger is rather soft and prone to splitting with heavier recoiling rounds, and the glass bedding serves primarily as a preventive measure. However, I personally glass bed the lug area when firing heavy-recoiling magnum calibers. If different rings are desired, Leupold, Warne, Redfield, Burris, Millet and Barska offer versions, and Weigand and Burris offer bases that clamp directly to the receiver to permit the use of cross-slot Weaver-style rings.The M77 receiver is dovetailed to accept factory supplied rings made of steel. Constructed of solid steel with four attaching screws per ring, they are very strong. The rings are available in different heights and allow proper mounting for virtually all common scopes. The Ruger mounting system has several advantages, including that there is no base to install, and neither can it work loose from recoil. 5 inch with carefully tailored handloads.Though early production rifles were fitted with a drilled and tapped round-top receiver that accepted traditional bases and rings (M77ST and M77PL), almost immediately the integral Ruger rings that attach directly to the receiver were offered as standard, with the “R” in 77R indicating factory rings included at no extra cost. 30-caliber barrels (as well as others) are of lesser quality, which results in groups that often vary from 1.5 to 2.5 inches (sometimes larger) even when using top-quality ammunition. On the other hand, many 7mm and. 338 Winchester Magnum rifles that each produce cloverleaf groups upon demand and are among my most accurate sporter-weight rifles.
