A sling swivel stud, sometimes called an "Uncle Mike type swivel", is a type of mounting point used for attaching slings [1] and bipods [2] to rifles.
In the context of firearms, a sling is a type of strap or harness designed to allow a shooter to conveniently carry a firearm on his/her body, and/or to aid in greater hit probability by allowing the firearm to be better braced and stabilized during aiming. Various types of slings offer their own advantages and disadvantages, and can generally be divided into several categories.
A bipod is an attachment, usually to a weapon, that helps support and steady it. The bipod provides significant stability along two axes of motion.
A rifle is a portable, long-barrelled firearm designed for long-range precision shooting, to be held with both hands and braced against the shoulder for stability during firing, and with a barrel that has a helical pattern of grooves ("rifling") cut into the bore walls. The term was originally rifled gun, with the word "rifle" referring to the machining process of creating grooving with cutting tools, and is now used for any long handheld device designed for aimed discharge activated by a trigger, such as air rifles and the personnel halting and stimulation response rifle. Rifles are used in warfare, law enforcement, hunting and shooting sports.
Sling swivels can be mounted to a long gun in various ways, for instance with wood or machine screws attached to the stock, [3] a barrel band, or by using adapters to other mounting standards such as Picatinny or M-LOK.
A long gun is a category of firearms with longer barrels than most other types. In small arms, a long gun is generally designed to be held by both hands and braced against the shoulder, in contrast to a handgun, which can be fired being held with a single hand. In the context of cannons and mounted firearms an artillery long gun would be contrasted with a howitzer or carronade.
A screw is a type of fastener, in some ways similar to a bolt, typically made of metal, and characterized by a helical ridge, known as a male thread. Screws are used to fasten materials by digging in and wedging into a material when turned, while the thread cuts grooves in the fastened material that may help pull fastened materials together and prevent pull-out. There are many screws for a variety of materials; those commonly fastened by screws include wood, sheet metal, and plastic.
The Picatinny rail, or Pic rail for short, also known as a MIL-STD-1913 rail or STANAG 2324 rail, is a military standard rail interface system that provides a mounting platform for firearm accessories. It was originally used for mounting scopes atop the receivers of larger caliber rifles. Once established, its use expanded to also attaching other accessories, such as: iron sights, tactical lights, laser aiming modules, night vision devices, reflex sights, foregrips, bipods, slings and bayonets.
The widest round part of the stud typically measures around 8.9 mm (0.350 inches), the spacing between the flats measure around 7.6 mm (0.3 inches) and the hole for mounting a sling adapter measures around 3.7 mm (0.145 inches).[ citation needed ]
Quick Detach sling mounts (QD), also called Flush Cup sling mounts, is a type of mounting point used for attaching slings. "QD sling swivel" usually refer to the part attached to the sling, while "flush cup" refer to the corresponding socket on the firearm.

The PKP Pecheneg is a Russian 7.62×54mmR general-purpose machine gun. It is a further development and modification of the PK machine gun. It is said to be more accurate than all its predecessors due to a heavier, non-removable, forced-air-cooling barrel with radial cooling ribs and a handle which eliminates the haze effect from hot gases and keeps the barrel cooler, making the weapon more reliable. Furthermore, the weapon is capable of having a telescopic sight or other sights mounted on it, increasing its accuracy and effective range.
