The Heckler & KochXM8 is a lightweight assault rifle system developed from the late 1990s to early 2000s. The rifle was designed by German small arms manufacturer Heckler & Koch (H&K), and shares design and engineering with their G36 rifle.
The Accuracy International Arctic Warfare rifle is a bolt-action sniper rifle designed and manufactured by the British company Accuracy International. It has proved popular as a civilian, police, and military rifle since its introduction in the 1980s. The rifles have some features that improve performance in very cold conditions without impairing operation in less extreme conditions.
The 1913 rail, also known as the Picatinny rail is an American rail integration system designed by Richard Swan that provides a mounting platform for firearm accessories. It forms part of the NATO standard STANAG 2324 rail. It was originally used for mounting of scopes atop the receivers of larger caliber rifles.
A telescopic sight, commonly called a scope informally, is an optical sighting device based on a refracting telescope. It is equipped with some form of a referencing pattern – known as a reticle – mounted in a focally appropriate position in its optical system to provide an accurate point of aim. Telescopic sights are used with all types of systems that require magnification in addition to reliable visual aiming, as opposed to non-magnifying iron sights, reflector (reflex) sights, holographic sights or laser sights, and are most commonly found on long-barrel firearms, particularly rifles, usually via a scope mount. Similar devices are also found on other platforms such as artillery, tanks and even aircraft. The optical components may be combined with optoelectronics to add night vision or smart device features.
The Ares Defense Shrike 5.56 is an air-cooled, dual-feed rifle for semi or full-auto configurations that fires the 5.56×45mm NATO cartridge. The Shrike 5.56 can be supplied as a complete weapon, or as an upper receiver “performance upgrade kit” to existing M16-type service rifles and carbines. it is named after the Shrike, a carnivorous passerine bird, and was designed by Geoffrey Herring.
A Weaver rail mount is a system to connect telescopic sights and other accessories to firearms and certain crossbows. It uses a pair of parallel rails and several slots perpendicular to these rails.
The Close Quarter Battle Receiver (CQBR) is a replacement upper receiver for the M4A1 Carbine, developed by the US Navy.
The SR-25 is a designated marksman rifle and semi-automatic sniper rifle designed by Eugene Stoner and manufactured by Knight's Armament Company.
A rail integration system is a generic term for a standardized system for attaching accessories to firearms. Rail systems are straight mounting brackets on the gun's receiver, handguard, or fore-end stock to allow sliding or variable-position attachments. An advantage of the multiple rail slots is the moveable positions to adjust for optimal placement of each item for a user's preferences, along with the ability to switch different items at different placements due to varying eye reliefs on gun sights.
The Sako TRG is a bolt-action sniper rifle line designed and manufactured by Finnish firearms manufacturer SAKO of Riihimäki. It is the successor to the SAKO TR-6 target rifle, and thus the letter G within the rifle's name is meant to represent number 7.
The M6 is a series of carbines designed and manufactured by LWRC International. It is based on the M4 carbine, with which it shares 80% of its parts. The 'M' model name is not a US military designation. Like the HK416, it features a proprietary short-stroke self-regulating gas piston system and bolt carrier/carrier key design, which prevents trapped gases from contacting the bolt carrier or receiver of the weapon. The manufacturer claims that this reduces the heating and carbon fouling of the internals, simplifies field maintenance, and improves reliability.
A barrel shroud is an external covering that envelops the barrel of a firearm, to prevent unwanted direct contact with the barrel. Moving coverings such as pistol slides, fore-end extension of the gunstock/chassis that do not fully encircle the barrel, and the receiver of a firearm itself are generally not described as barrel shrouds, though they can functionally act as such.
The T91 is a gas-operated, magazine-fed, assault rifle produced by the 205th Armory of National Defense in Republic of China. It is based on the proven T86 assault rifle, incorporating features from the M16 and AR-18 with more modern features. The T91 is lighter and shorter than the T65 it replaces, and has an adjustable 3-position telescoping stock.
The karabinek wz. 1996 Mini-Beryl is a Polish compact assault rifle (carbine) derived from the FB Beryl service rifle and chambered for 5.56×45mm. It was developed in parallel with the wz. 1996 Beryl by the "Łucznik" Arms Factory in Radom and introduced into service with the Polish Armed Forces in 1997 as the 5,56 mm karabinek krotki wz. 1996.
The NATO Accessory Rail (NAR), defined by NATO Standardization Agreement (STANAG) 4694, is a rail interface system standard for mounting accessory equipment such as telescopic sights, tactical lights, laser aiming modules, night vision devices, reflex sights, foregrips, bipods and bayonets to small arms such as rifles and pistols.
M-LOK, for Modular Lock, is a firearm rail interface system developed and patented by Magpul Industries. The license is free-of-charge, but subject to an approval process.
The UIT rail, also known as Anschutz rail, is a standard used for mounting slings and other gun accessories in competition shooting, and is essentially a T-slot track shaped aluminium extrusion profile accepting attachments in the form of T-slot nuts, or similar.
A dovetail rail or dovetail mount can refer to several types of sliding rail system found on firearms, primarily for mounting telescopic sights. Colloquially, the term dovetail rail usually refer to any straight mounting bracket with an inverted trapezoid (dovetail) cross-section running parallel to the bore for mounting a scope or diopter sight to a rifle. These are sometimes also called "tip-off" mounts, and allow the user to easily take on or off the sight. Dovetail mount can also refer to a dovetail track running perpendicular to the bore.
Scope mounts are rigid implements used to attach (typically) a telescopic sight or other types of optical sights onto a firearm. The mount can be made integral to the scope body or, more commonly, an external fitting that clamp onto the scope tube via screw-tightened rings. The scope and mount are then fastened onto compatible interfaces on the weapon. Words such as mounts and bases are used somewhat loosely, and can refer to several different parts which are either used together or in place of each other as ways to mount optical sights to firearms.
Noveske Rifleworks is a high end American firearms company. They are headquartered in Grants Pass, Oregon and are known for their work with the AR-15 platform and the KeyMod system.
