The 7.62 mm caliber is a nominal caliber used for a number of different cartridges.

Bolt-action is a type of manual firearm action that is operated by directly manipulating the bolt via a bolt handle, most commonly placed on the right-hand side of the firearm. The majority of bolt-action firearms are rifles, but there are also some variants of shotguns and handguns that are bolt-action.
In firearms terminology, an action is the functional mechanism of a breech-loading firearm that handles the ammunition cartridges, or the method by which that mechanism works. Actions are technically not present on muzzleloaders, as all those are single-shot firearms with a closed off breech with the powder and projectile manually loaded from the muzzle. Instead, the muzzleloader ignition mechanism is referred to as the lock.

In firearms operating systems, the term roller locked refers to locking the bolt with rollers. Notable examples of firearms using this method are the MG 42 general-purpose machine gun and the CZ 52 semi-automatic pistol. It was also applied in the experimental Gerät 03 semi-automatic rifle and Gerät 06 and EM-1 experimental assault rifles. The MG 42's lineage continued past World War II, forming the basis for the nearly identical MG1, chambered in 7.62×51mm NATO, which subsequently evolved into the MG1A3, and later the Bundeswehr's MG 3, Italian MG 42/59, and Austrian MG 74. It also spawned the Yugoslav unlicensed nearly identical Zastava M53.

Mauser M1996, also known as Mauser M96 or Mauser M96 S, is a straight-pull rifle which was introduced by the German firearms manufacturer Mauser in 1996. The rifle had a blind magazine which was loaded from the top, and the bolt was operated by pulling the bolt handle about 30 degrees along the longitudinal axis of the firearm. The factory trigger pull weight was a little over 2 kg, and was not adjustable. Due to the construction of the trigger geometry it has proven difficult to lighten the trigger pull without experiencing problems with light primer strikes. The locking lugs are angled slightly to aid with primary extraction. The rifle was delivered with a traditional slim wooden stock where the height of the comb was adapted for shooting with iron sights. The receiver came drilled and tapped for attaching a scope mount.
