The Ruger Precision Rimfire is a rimfire bolt-action rifle manufactured by Sturm, Ruger & Co. in the United States. The firearm has some visual similarities with the larger centerfire Ruger Precision Rifle , and both are marketed as budget precision rifles.
Since #6–48 and M3.5x0.6 have near identical diameters and almost equal pitch, there is a potential for confusion, and upon mixing the wrong screw will enter the threads, but will gradually become tighter to screw until the thread is destroyed. In case of damage, the hole must often be drilled and re-threaded, and M4x0.7 or #8–40 may then ...
For example, factory and aftermarket receivers using the Remington 700 footprint are produced with various types of action threads, all with a 26.99 mm (1 + 1 ⁄ 16 in) diameter, but with a pitch of either a 1.588 mm (16 TPI, Remington standard), 1.411 mm (18 TPI) or 1.270 mm (20 TPI, Savage standard).
The bolt of the rifle pushes a cartridge from the metal feeding lip of the magazine with each shot, allowing the next cartridge to feed into place. The rotary magazine is also used by the Ruger's American Rimfire series bolt-action rifles, as well as the 10/22-footprinted "Summit" toggle-action rifles produced by Primary Weapon Systems/Volquartsen.
Animation showing the operation of a screw. As the screw shaft rotates, the nut moves linearly along the shaft. This is a type called a lead screw. A machine used in schools to demonstrate the action of a screw, from 1912. It consists of a threaded shaft through a threaded hole in a stationary mount.
The Anschütz Fortner action used in biathlon is a good example of an ergonomical straight-pull rifle with good economy of motion and high operating speed. The action lever is located close to the trigger, and is accessed by slightly moving the index finger off the trigger. Pulling the lever rearwards ejects the spent casing.
The applied torque causes the bolt to "climb" the thread causing a tensioning of the bolt and an equivalent compression in the components being fastened by the bolt. The preload developed in a bolt is due to the applied torque and is a function of the bolt diameter, the geometry of the threads, and the coefficients of friction that exist in the ...
Adequate screw torque setting between the action and the stock is also important for the overall rigidity of the system. Some companies, such as Savage Arms , have even introduced features like floating bolt head to provide better bolt-breech engagement for more adequate breech seal and headspacing .
