Attaching the barrel to the receiver using a barrel nut and a barrel with a shoulder is an alternative to action threads, which has been used in firearms such as the Sten gun and AR-15. Hand tools Quick barrel change systems is an increasingly popular alternative, as seen in for example SIG Sauer 200 STR, Roessler Titan or Blaser R8.
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.
While standard rifle barrels taper from breech to muzzle, high precision rifles will often use a barrel with far less taper, called a heavy barrel, sometimes leaving the barrel cylindrical all the way to the muzzle, called a bull barrel. Either technique greatly increases the stiffness of the barrel by enlarging the average diameter, but this ...
Gun dynamics describes the physical causes of barrel and shot vibration, and the effect they may have on accuracy and consistency. It is employed to predict firearm performance, such as recoil , using theoretical methods and mathematical modelling techniques.
The hand-lapping technique uses a wooden or soft metal rod to pull or push the slug through the bore, while the newer fire-lapping technique uses specially loaded, low-power cartridges to push abrasive-covered soft-lead bullets down the barrel. Another issue that has an effect on the barrel's hold on the bullet is the rifling.
The Ruger American Rifle is the first to use the trademarked "Ruger Marksman Adjustable™" trigger, which is similar in design to the Savage "AccuTrigger" and allows the user to adjust the weight of pull between 3–5 lb (1.4–2.3 kg) by means of turning a set screw on the trigger housing. [2]
A muzzle brake or recoil compensator is a device connected to, or a feature integral (ported barrel) to the construction of, the muzzle or barrel of a firearm or cannon that is intended to redirect a portion of propellant gases to counter recoil and unwanted muzzle rise. [1]
It also lacks the "Gunsite Scout Rifle" name and logo found on the grip cap. [5] As of 2013, the standard model Ruger Gunsite Scout rifle with the 16.5 inch barrel and flash hider and the Matte Stainless is now available for sale in Australia, Canada and other countries. In addition, a model chambered in 5.56×45mm NATO was announced in 2014. [6]
