Scope mounts for Winchester Model 70 LA

About the Company

In the year 1866, more than 150 years ago, Oliver Winchester left a significant mark on the history of rifle-making when he founded the Winchester Repeating Arms Company with the intention of producing exceptional guns and ammunition. Oliver Winchester, “a man of vision and influence,” as many considered him, fulfilled his intention and built an industrial empire around the lever-action rifle. Sporting a polished brass receiver, the Model 1866 “Yellow Boy” lever-action rifle was the first gun to bear the Winchester name. Fast forward a few years, to 1880, Oliver Winchester died at age 70, but his legacy remained.  The Winchester Model 1892 lever-action rifle soon proved itself to be the moviemaker’s favorite, while revolvers chambered in .38-40 Win., .44-40 Win. and .45 Colt were also well received.

Winchester helped pave the way for modern-day rifle manufacturers, and their decades of experience and craftsmanship can also be seen in their high-quality ammunition. They offer a variety of ammo for handguns, rifles, shotguns, and rimfire rifles. Today, the Winchester brand is owned by the Olin Corporation and made up of numerous members who are devoted to the maintenance, collecting, and learning about Winchester rifles and related products, as well as the role these products held in shaping the history of America’s firearms. 

About the Rifle

Winchester Model 70 LA (Standard)

Winchester Model 70 is a bolt-action repeating rifle first introduced in 1936. It was the successor to the Model 54 and achieved great success in the USA. It is still often called “The Rifleman’s rifle”, and in 1999 it was named the “bolt-action rifle of the century” by Shooting Times magazine.

In the years since its release, Model 70 has gone through a lot of changes and has been produced in 4 different versions. The first version, known as the pre-1964 version, was made from 1936 to 1964. It featured a controlled-feed action with two locking lugs, a steel receiver and had a premium price tag. The second version was made from 1964 to 1992 and is known as the post-1964 version. It was a redesign aimed at reducing costs to produce a more budget-friendly line of rifles but ended up being considered a disappointment by rifle enthusiasts because of its push-feed action, overall simplified design, and feeding issues. The third version of M70 was introduced in 1992 and in many ways represented a return to the pre-1964 version, except that it came equipped with a controlled round push feed (or CRPF) action. At the same time, they also released M70 Classic, which was in essence a reintroduction of the pre-1964 version (this one had a controlled-feed action). And in 2007, yet another, improved version of the Winchester M70 was introduced. This version has a lighter, but at the same time stronger action than the pre-1964 version because of CNC machining used to create the steel receiver. It still features a controlled-feed action and a three-position safety, which enables fire when pushed forward and locks the rifle when pushed backward, while the middle position enables the chamber to be unloaded, locks the trigger, but at the same time allows bolt movement.

Up to 1984, one disadvantage of the M70 was that it was made in only one receiver length, no matter the caliber, which meant that the receiver was too long for some calibers to work as smoothly as theyshould. They fixed this by introducing shorter actions, so that now there are 5 action lengths available: WSSM, WSM, short, long and extra-long.
