Advanced Combat Optical Gunsight
The Advanced Combat Optical Gunsight (ACOG) is a series of prismatic telescopic sights manufactured by Trijicon. The ACOG was originally designed to be used on the M16 rifle and M4 carbine, but Trijicon has also developed ACOG accessories for other firearms. Models provide fixed-power magnification levels from 1.25× to 6×. ACOG reticles are illuminated at night by an internal tritium phosphor. Some versions have an additional daytime reticle illumination via a passive external fiberoptic light pipe or are LED-illuminated using a dry battery. The first ACOG model, known as the TA01, was released in 1987. History The first ACOG model, known as the TA01, was released in 1987. In 1995, United States Special Operations Command selected the 4×32 TA01 as the official scope for the M4 carbine and purchased 12,000 units from Trijicon. Between 2004 and 2005, the ACOG was selected as the official Rifle Combat Optic of the United States Marine Corps, prompting Trijicon to produce 100,000 ...

Bullet Drop Compensation
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. The optical components may be combined with optoelectronics to add night vision or smart device features. History The first experiments directed to give shooters optical aiming aids go back to the early 17th century. For centuries, different optical aiming aids and primitive predecessors of telescopic sights were created that had practical or ...

Steyr AUG
The Steyr AUG () is an Austrian bullpup assault rifle chambered for the 5.56×45mm NATO intermediate cartridge, designed in the 1960s by Steyr-Daimler-Puch, and now manufactured by Steyr Arms GmbH & Co KG. It was adopted by the Austrian Army in 1978 as the StG 77 (''Sturmgewehr 77''), where it replaced the 7.62×51mm NATO StG 58 automatic rifle (a licence-built FN FAL).Ezell (1993) p. 223 In production since 1978, it is the standard small arm of the ''Bundesheer'' and various Austrian federal police units, and its variants have also been adopted by the armed forces of dozens of countries, with some using it as a standard-issue service rifle. Steyr AUG importation into the United States began in the 1980s as the AUG/SA (SA denoting semiautomatic). President George H.W. Bush banned the AUG via an executive order under the 1989 Assault Weapon Import Ban. Six years into the ban, AUG buyers gained a reprieve as cosmetic changes to the carbine's design allowed importation on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FN SCAR
The FN SCAR (Special Operations Forces Combat Assault Rifle) is a family of gas-operated short-stroke gas piston automatic rifles developed by Belgian manufacturer FN Herstal (FN) in 2004. It is constructed with modularity for the United States Special Operations Command (SOCOM) to satisfy the requirements of the SCAR competition. This family of rifles consist of two main types. The SCAR-L, for "light", is chambered in 5.56×45mm NATO and the SCAR-H, for "heavy", is chambered in 7.62×51mm NATO. Both are available in ''Close Quarters Combat'' (''CQC''), ''Standard'' (''STD''), and ''Long Barrel'' (''LB'') variants.

Enfield L85A2
The SA80 (Small Arms for the 1980s) is a British family of 5.56×45mm NATO service weapons used by the British Army. The L85 Rifle variant has been the standard issue service rifle of the British Armed Forces since 1987, replacing the L1A1 Self-Loading Rifle. The first prototypes were created in 1976, with production of the A1 variant starting in 1985 and ending in 1994. The A2 variant came to be as the result of a significant upgrade in the early 2000s by Heckler & Koch and remains in service as of 2020. The A3 variant was first issued in 2018 with several new improvements. The remainder of the SA80 family comprises the L86 Light Support Weapon, the short-barrelled L22 Carbine and the L98 Cadet rifle. The SA80 was the last in a long line of British weapons (including the Lee–Enfield family) to come from the Royal Small Arms Factory, the national arms development and production facility at Enfield Lock, before its weapons factory was closed down in 1988.

Bushmaster ACR
The Adaptive Combat Rifle (ACR) is a modular assault rifle designed by Magpul Industries of Austin, Texas, and known initially as the Masada. In late January 2008, Bushmaster Firearms International entered into a licensing agreement with Magpul whereby Bushmaster would take over production, future development, and sales of the Masada. It was then known as the Bushmaster ACR. However, Remington Arms is contracted to manufacture the rifle for the US military and US law enforcement agencies, in which it is known as the Remington ACR. Hence, Remington Arms is responsible for the selective fire version of the ACR, while Bushmaster Firearms International is responsible for the semi-automatic only version. The Remington ACR was one of the weapons displayed to U.S. Army officials during an invitation-only Industry Day on November 13, 2008. The goal of the Industry Day was to review current carbine technology prior to writing formal requirements for a future replacement for the M4 Car ...

Heckler & Koch HK416
The Heckler & Koch HK416 is a gas-operated assault rifle chambered for the 5.56×45mm NATO cartridge. It is designed and manufactured by the German company Heckler & Koch. Although the design is based on the AR-15 class of firearm (specifically the Colt M4 carbine family issued to the U.S. military), it uses a proprietary short-stroke, gas piston system from Heckler & Koch's earlier G36 family of rifles. The HK416 is the standard assault rifle of the Norwegian Armed Forces, and it has been selected by the French Armed Forces to replace the FAMAS. Other users of the HK416 include the German Army and the Irish Army Ranger Wing, as well as the US Navy's SEAL Team Six, who used it to kill Osama Bin Laden in 2011. History The United States Army's Delta Force, at the request of R&D NCO Larry Vickers, collaborated with Heckler & Koch to develop a new carbine in the 1990s for use in close quarters combat. At this point, they were equipped with the Heckler & Koch MP5, whose 9mm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SIG SG 550
The SG 550 is an assault rifle manufactured by Swiss Arms AG (formerly a division of Schweizerische Industrie Gesellschaft, now known as SIG Holding AG) in Switzerland. "SG" is an abbreviation for ''Sturmgewehr'' ("assault rifle"). The rifle is based on the earlier 5.56×45mm NATO SIG SG 540. History Development In 1978, the Swiss armed forces formulated requirements for a successor to the Stgw 57 battle rifle (known commercially as the SG 510) using the 7.5×55mm GP 11 cartridge. Emphasis was placed on modularity; the weapon family was to include several variants of the base design, including a compact carbine that would be issued to rear-echelon and support troops, command staff, vehicle crews, special forces personnel and paratroopers. Another aim was to reduce the overall weight of the rifle while retaining comparable or improved accuracy out to 300 m. The solicitation was narrowed down to two designs: the W+F C42 (developed by the state-owned Waffenfabrik Bern, using ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beretta AR70/90
The Beretta AR70/90 is a gas operated assault rifle chambered for the 5.56×45 mm NATO cartridge, and is the standard issue service rifle of the Italian Armed Forces. The weapon is also designed to be fitted with a rifle grenade, and has grenade sights. The AR series comes in many variants such as the AR90, with a wire folding stock, for use by paratroopers. History Beretta AR70 In 1963, SIG and Beretta began a joint development of the SIG SG 530. In 1968, Beretta decided to cease development with SIG, with the latter developer choosing to continue work on the SG 530. Beretta instead pursued development of its own off-shoot of the SG 530, using the information and experience they had gained from the project. The result was the Beretta AR70, which externally resembled its parent weapon, the SG 530, while differing in the internal firing mechanism/locking system. The AR-70 was introduced in 1972. Following the successful testing of the rifle's capabilities, it was adopted b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waterproof
Waterproofing is the process of making an object or structure waterproof or water-resistant so that it remains relatively unaffected by water or resisting the ingress of water under specified conditions. Such items may be used in wet environments or underwater to specified depths. ''Water-resistant'' and ''waterproof'' often refer to resistance to penetration of water in its liquid state and possibly under pressure, whereas '' damp proof'' refers to resistance to humidity or dampness. Permeation of water vapour through a material or structure is reported as a moisture vapor transmission rate (MVTR). The hulls of boats and ships were once waterproofed by applying tar or pitch. Modern items may be waterproofed by applying water-repellent coatings or by sealing seams with gaskets or o-rings. Waterproofing is used in reference to building structures (such as basements, decks, or wet areas), watercraft, canvas, clothing (raincoats or waders), electronic devices and paper packag ...

Picatinny Rail
The Picatinny rail ( or ), or Pic rail for short, also known as a MIL-STD-1913 rail, 1913 rail or STANAG 2324 rail (cancelled), is a military standard rail interface system that provides a mounting platform for firearm accessories. It was originally used for mounting of 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, holographic sights, foregrips, bipods, slings and bayonets. An updated version of the rail is adopted as a NATO standard as the STANAG 4694 NATO Accessory Rail. Significance Because of their many uses, Picatinny rails and accessories have replaced iron sights in the design of many firearms and available as aftermarket add-on parts for most actions that do not have them integrated, and they are also on the undersides of semi-automatic pistol frames and grips. When adding a Picat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reflex Sight
A reflector sight or reflex sight is an optical sight that allows the user to look through a partially reflecting glass element and see an illuminated projection of an aiming point or some other image superimposed on the field of view. These sights work on the simple optical principle that anything at the focus of a lens or curved mirror (such as an illuminated reticle) will appear to be sitting in front of the viewer at infinity. Reflector sights employ some sort of "reflector" to allow the viewer to see the infinity image and the field of view at the same time, either by bouncing the image created by lens off a slanted glass plate, or by using a mostly clear curved glass reflector that images the reticle while the viewer looks through the reflector. Since the reticle is at infinity it stays in alignment with the device to which the sight is attached regardless of the viewer's eye position, removing most of the parallax and other sighting errors found in simple sighting devices. ...
