Like the 10/22, the MkII is supported with a variety of after-market accessories. The 22/45 is similar to the Ruger Standard family of pistols but features a different grip angle, Ruger Casting has plants in Newport, New Hampshire and Prescott, Arizona, making ferrous, ductile iron and commercial titanium castings. Ruger Golf makes steel and titanium castings for golf clubs made by a number of different brands, Sturm, Ruger stock has been publicly traded since 1969, and became a New York Stock Exchange company in 1990. After Alex Sturm’s death in 1951, William B, Ruger continued to direct the company until his death in 2002. From 1949 through 2004, Ruger manufactured over 20 million firearms, and currently offers models for hunting, target shooting, self-defense, collecting, and law enforcement.

In firearms, rifling consists of helical grooves in the internal surface of a guns barrel, which impart a spin to a projectile around its long axis. This spin serves to stabilize the projectile, improving its aerodynamic stability. Rifling is often described by its twist rate, which indicates the distance the rifling takes to complete one revolution, such as 1 turn in 10 inches. A shorter distance indicates a faster twist, meaning that for a given velocity the projectile will be rotating at a spin rate. Barrels intended for long, small-diameter bullets, such as the ultra-low-drag, 80-grain 0.223 inch bullets, extremely long projectiles such as flechettes may require high twist rates, these projectiles must be inherently stable, and are often fired from a smoothbore barrel. Muskets were smoothbore, large caliber weapons using ball-shaped ammunition fired at low velocity. Due to the high cost and great difficulty of manufacturing, and the need to load readily from the muzzle. Consequently, on firing the ball bounced off the sides of the barrel when fired, barrel rifling was invented in Augsburg, Germany in 1498. In 1520 August Kotter, an armourer of Nuremberg, Germany improved upon this work, though true rifling dates from the mid-16th century, it did not become commonplace until the nineteenth century. The most successful weapons using rifling with black powder were breech loaders such as the Queen Anne pistol, the grooves most commonly used in modern rifling have fairly sharp edges. More recently, polygonal rifling, a throwback to the earliest types of rifling, has become popular, polygonal barrels tend to have longer service lives because the reduction of the sharp edges of the land reduces erosion of the barrel. Supporters of polygonal rifling also claim higher velocities and greater accuracy, polygonal rifling is currently seen on pistols from CZ, Heckler & Koch, Glock, Tanfoglio, and Kahr Arms, as well as the Desert Eagle. Such guns have achieved significant increases in velocity and range. Examples include the South African G5 and the German PzH2000, gain-twist rifling begins with very little change in the projectiles angular momentum during the first few inches of bullet travel after ignition during the transition from chamber to throat. This enables the bullet to remain undisturbed and trued to the case mouth. After engaging the rifling the bullet is progressively subjected to accelerated angular momentum as burning powder propels it down the barrel. By only gradually increasing the rate, torque is spread along a much longer section of barrel. Gain-twist rifling was used as early as the American Civil War, colt Army and Navy revolvers both employed gain-twist rifling
The.30 refers to the caliber of the bullet, and the 06 refers to the year the cartridge was adopted—1906. It replaced the. 30-03, 6mm Lee Navy, and. 30-40 Krag cartridges and it remains a very popular sporting round, with ammunition produced by all major manufacturers. In the early 1890s, the U. S. military adopted the smokeless powder. 30-40 Krag rimmed cartridge, the 1894 version of that cartridge used a 220-grain round-nose bullet. Around 1901, the U. S. started developing an experimental rimless cartridge for a Mauser action with box magazine and that led to the 1903. 30-03 rimless service round that used the same 220-grain round-nose bullet as the Krag. The. 30-03 achieved a velocity of 2,300 ft/s. Consequently, the round-nosed U. S. 30-03 service cartridge was falling behind. For these reasons, the U. S. military developed a new, lighter, cartridge in 1906, the cartridge was loaded with Military Rifle 21 propellant, and its maximum range was claimed to be 4,700 yd. The M1903 Springfield rifle, which had been introduced alongside the. 30-03 cartridge, was modified to accept the new. 30-06 Springfield cartridge. Modifications to the rifle included shortening the barrel at its breech and resizing the chamber, other changes to the rifle included elimination of the troublesome rod bayonet of the earlier Springfield rifles. The M1906 maximum range was originally overstated, when the M1906 cartridge was developed, the range tests had been done to only 1,800 yards, distances beyond that were estimated, but the estimate for extreme range was wrong by almost 40 percent. The range discrepancy became evident during World War I, before the widespread employment of light mortars and artillery, long-range machine gun barrage or indirect fires were considered important in U. S. infantry tactics. When the US entered World War I, it did not have machine guns, so it acquired British. When those weapons were replaced with US machine guns firing the M1906 round. Firing tests performed around 1918 at Borden Brook Reservoir, Miami, patrone was inroduced in 1914 and used a 197. 5-grain s. S. - schweres Spitzgeschoß boat-tail bullet which had a maximum range of approximately 5,140 yd. Its maximum range was approximately 5,500 yd. Additionally, wartime surplus totaled over 2 billion rounds of ammunition. Army regulations called for training use of the oldest ammunition first, as a result, the older. 30-06 ammunition was expended for training, stocks of.30 M1 Ball ammunition were allowed to slowly grow until all of the older M1906 ammunition had been fired. By 1936, it was discovered that the range of the.30 M1 Ball ammunition with its boat-tailed spitzer bullets was beyond the safety limitations of many ranges. An emergency order was made to manufacture quantities of ammunition that matched the ballistics of the earlier M1906 cartridge as soon as possible
The Mini-14 is a lightweight.223 caliber semi-automatic rifle manufactured by Sturm, Ruger & Co. that is popular with law enforcement, security personnel, hunters, ranchers and target shooters. It is made in a number of variants including the Ranch Rifle with a scope base on the receiver, the Mini Thirty which is chambered for 7. 62×39mm, and the AC-556. The Mini-14 was first introduced in 1973 by Sturm, Ruger & Co, the name Mini-14 was coined because it resembles a smaller version of the military M14 rifle. Designed by L. James Sullivan and William B, Ruger, it incorporated numerous innovations and cost-saving engineering changes. The Mini-14 rifle employs an investment cast, heat-treated receiver and is similar to the M1 Garand rifle, with a self-cleaning. Initial rifles were produced with a complex, exposed bolt hold open device with no button for manual engagement, stocks were somewhat angular and heat shields were made of wood. These rifles, with serial number prefixes before 181, were tooled and redesigned with a new stock, new bolt hold-open mechanism, the original Mini-14 rifle had a rear aperture sight with large protective wings, and no integral scope bases. In 1982, Ruger introduced the Ranch Rifle with a scope base on the receiver. It introduced a heat shield and ejected spent cartridge cases at a lower angle to avoid hitting low-mounted scopes. In 1987, Ruger introduced the Mini Thirty rifle chambered for the Russian 7. 62×39mm cartridge, at the time, large quantities of surplus military ammunition were being imported into the United States at rock bottom prices. Also, the 7. 62×39mm is ballistically similar to the. 30-30 Winchester cartridge, as a result, the Mini Thirty proved to be an effective deer rifle. The design was overhauled to improve accuracy and update the styling while at the same time reducing production costs, the standard Mini-14 was discontinued and the name became the family name for all Mini-14 type rifles. These upgraded rifles have serial numbers beginning with 580 and are referred to as 580 series Ranch Rifles. They have new iron sights and a gas system designed to reduce barrel vibration and are capable of shooting 2 inch groups at 100 yards or 2 minute of angle accuracy. Sometime between 2007 and 2008, Ruger added a heavier tapered barrel to the Mini series, the heavier barrel had an overall larger diameter with the barrel visibly becoming thicker in the final inches as the barrel approaches the gas block from the muzzle. These changes combined with tighter tolerances result in greater potential accuracy, all Mini-14 type rifles are available in stainless steel or blued finish with hardwood, synthetic, or laminated stocks with 16. 12-inch or 18. 5-inch barrels. Most Mini-14s have a classic sporter appearance in contrast to comparable autoloading rifles such as the AK-47, however, Ruger now offers some Mini-14 rifles in a black ATI-brand adjustable folding stock with a pistol grip. Also, Ruger factory-made 5-, 10-, 20- and 30-round steel magazines are available along with numerous aftermarket options
The SR-556 is a semi-automatic rifle carbine manufactured by U. S. firearms company Sturm, Ruger & Company, Inc. The rifle was introduced in 2009, marking Rugers entry into the popular AR-15 market, and it would continue with a.308 AR-10 variant and it is one of several new AR-15 rifles to use gas piston operation. In January 2016 Ruger discontinued all SR-556 rifles and introduced a new Takedown variant with a lightweight Keymod handguard, the rifle features a patent-pending, two stage piston mechanism as opposed to the standard AR-15 direct impingement system. Gas flow is controlled by a four position regulator, several key parts, such as the short stroke gas piston, gas regulator, and bolt/carrier group are chrome plated. The bolt carrier features an integral lug in place of the AR-15s gas key, the flash hider is similar to Rugers AC-556 and Mini-14GB. The SR-556SC comes with three 10-round magazines and does not have the flash hider or collapsible stock, making it compliant in several states with restrictive assault rifle laws. The barrel is 409 millimetres, chrome lined, and features a six groove, in August 2010, Ruger announced that the rifle would be offered in the 6. 8mm Remington SPC cartridge. Pricing suggests that its intended to compete with other entry level AR-15s such as the Smith & Wesson M&P15 Sport, Rugers introduction of the SR-556 was met with some criticism for its high price tag. The SR-556 was also criticized for its weight than other AR-15s. Ruger addressed these shortcomings by introducing a lighter and less expensive rifle, Ruger Official Site Gunblast Article Ruger AR-556 official site
The Ruger SR-Series is a line of semi-automatic pistols manufactured by Sturm, Ruger & Company. At 1.18 in thick through the grip, it is touted by Ruger as one of the thinnest double-stack pistols available, the SR-series has been marketed as a backup/concealment weapon for law enforcement as well as for civilian concealed carry. The Ruger SR9 chambered for the 9×19mm Parabellum cartridge was introduced in October 2007, the Ruger SR40 chambered for the.40 S&W cartridge came out in October 2010, and the compact SR40c in June 2011. Ruger specifically designed the SR9 pistol to address the very active and profitable concealed-carry handgun market segment, the SR9 is the first large-caliber striker fired pistol designed and manufactured by Sturm Ruger. Similar to Glocks safe action, the striker fired SR9 features a pre-set trigger, with this type of action, the striker is partially cocked when the slide is cycled, then is fully cocked and released when the trigger is pulled. Due to safety concerns, the long and heavy trigger pull of this type is seen as ideal for law enforcement. The SR9 and SR9c have identical trigger groups, the difference in trigger-pull is most likely due to variances between individual guns, and not to a change in specs by Ruger between the models. The trigger travel is 7.8 mm, the SR9 is recoil operated with a locked breech. It features a staggered column box magazine with a capacity of 17 rounds, the slide is available in either brushed or blackened through-hardened stainless steel, and the frame is fiberglass-reinforced nylon polymer, resistant to warping or failure. The frame is offered in black or olive drab, the SR9 also has a reversible backstrap which allows the owner to select either a flat or arched grip housing, based on personal preference. In addition, the SR9 sports a Picatinny rail for the mounting of laser sights, the SR9 also features a magazine disconnector. The Ruger SR9 can safely be dry fired with an empty magazine in the pistol, the SR9s open iron sights are of the three-dot enhanced contrast variety, and offer drift adjustment on both front and rear blades for windage, as well as rear-sight adjustment for elevation. The Ruger SR-series factory accessories consist of spare magazines, a grip adapter, the Ruger SR9 started to ship in October 2007. It is the first model of the Ruger SR-series, the full-size Ruger SR9 is chambered in 9×19mm Parabellum, and it is shipped with two 17-round, flush-fit magazines and a loading tool. An economy version of the SR9, the 9E, was released in 2014, the Ruger SR9c started to ship in January 2010, according to Ruger. The SR9c is lighter and dimensionally smaller compared to the SR9, the manual safety, adjustable rear sights, and updated version of the trigger are all present in the compact version also. In contrast to the SR9 recoil spring assembly the SR9c pistols are fitted with a recoil spring assembly. The SR9c is normally supplied with two magazines, the standard 10-round compact magazine features a flat bottom floor plate, with an extended floor plate also included
