Barrett MRAD
The Barrett MRAD (Multi-role Adaptive Design) is a bolt-action sniper rifle designed by Barrett to meet the requirements of the SOCOM PSR. The MRAD is based on the Barrett 98B and includes a number of modifications and improvements. The Barrett MRAD was named the 2012 Rifle of the Year by the NRA. Design After the United States Special Operations Command (USSOCOM) announced their desire for a new precision sniper rifle in December 2009, Barrett created the MRAD in accordance with the specifications laid out by SOCOM. Building off of the successful Barrett 98B, the MRAD features multiple improvements such as a folding stock which allows the rifle to be transported more easily. When folded, the stock latches around the bolt handle which increases the security of transporting the rifle without increasing the width when it is unfolded. A major MRAD feature (and requirement of the military PSR solicitation) is a field-changeable barrel/caliber capability. Loosening two Torx sc ...

Sniper Rifle
A sniper rifle is a high-precision, long-range rifle. Requirements include accuracy, reliability, mobility, concealment and optics for anti-personnel, anti-materiel and surveillance uses of the military sniper. The modern sniper rifle is a portable shoulder-fired weapon system with a choice between bolt-action or semi-automatic action, fitted with a telescopic sight for extreme accuracy and chambered for a high-ballistic performance centerfire cartridge. History The Whitworth rifle was arguably the first long-range sniper rifle in the world. Designed by Sir Joseph Whitworth, a prominent British engineer, it used barrels with hexagonal polygonal rifling, which meant that the projectile did not have to bite into the rifling grooves as was done with conventional rifling. His rifle was far more accurate than the Pattern 1853 Enfield, which had shown some weaknesses during the recent Crimean War. At trials in 1857, which tested the accuracy and range of both weapons, Whitworth' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Precision Sniper Rifle
The Precision Sniper Rifle (PSR) was a program by United States Special Operations Command to replace all bolt-action sniper rifles in use by United States special operations snipers with a single bolt-action rifle chambered for a large caliber Magnum chambering like .300 Win Mag, and .338 Lapua Magnum. The solicitation was placed on January 15, 2009. The contract was awarded to Remington Arms for their Modular Sniper Rifle as Mk 21 Precision Sniper Rifle History A 2008 United States military market survey for a Precision Sniper Rifle (PSR) called for 1 minute of arc (0.3 milliradian) extreme vertical spread for all shots in a 5-round group fired at targets at 300, 600, 900, 1,200 and 1,500 meters.

AR-15
An AR-15-style rifle is any lightweight semi-automatic rifle based on the Colt AR-15 design. The original ArmaLite AR-15 is a scaled-down derivative of Eugene Stoner's ArmaLite AR-10 design. The then Fairchild Engine and Airplane Corporation division ArmaLite sold the patent and trademarks to Colt's Manufacturing Company in 1959. After most of Colt's patents for the Colt AR-15 expired in 1977, many firearm manufacturers began to produce copies of the Colt AR-15 under various names. While the patents are expired, Colt retained the trademark of the AR-15 and is the sole manufacturer able to label their firearms as ''AR-15''. The "AR" in Colt AR-15 stands for "ArmaLite Rifle", not " assault rifle". The Federal Assault Weapons Ban restricted the sale of the Colt AR-15 and some derivatives in the United States from 1994 to 2004, although it did not affect rifles with fewer listed features. After the term modern sporting rifles was coined in 2009 by the US National Shooting Sports F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Length-of-pull
Length of pull (sometimes abbreviated as LOP) is the distance from the trigger to the part of a rifle or shotgun which fits against the shoulder of the shooter. Length of pull is an important ergonomic factor for ease of use; and optimum length of pull may vary with the size of the shooter, the thickness of chest clothing and body armor being worn, and whether the shooter is firing from a standing, sitting, or prone position. Variation Many rifles and shotguns are manufactured with a standard length of pull assumed to fit most shooters. This is often approximately for rifles and about longer for shotguns. Shooters with short arms may find the buttstock dragging along the underside of their arm as they attempt to raise the firearm into firing position. Shooters with broad shoulders or a long neck may experience face injuries from collision with the telescopic sight or thumb of the trigger hand as the firearm recoils. Modern firearms may be equipped with a telescoping stock or remov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fluting (firearms)
In firearms terminology, fluting refers to the removal of material from a cylindrical surface, usually creating grooves. This is most often the barrel of a rifle, though it may also refer to the cylinder of a revolver or the bolt of a bolt action rifle. In contrast to rifle barrels and revolver cylinders, rifle bolts are normally helically fluted, though helical fluting is sometimes also applied to rifle barrels. The main purpose of fluting is to reduce weight, and to a lesser extent increase rigidity for a given total weight or increase surface area to make the barrels less susceptible for overheating for a given total weight. However, for a given diameter, while a fluted barrel may cool more quickly, a non-fluted barrel will be stiffer and be able to absorb a larger amount of total heat at the price of additional total weight. In barrel chamber In the barrel chamber, fluting refers to gas relief flutes/grooves used to ease the extraction of cartridges. They may also ...

Stock (firearms)
A gunstock or often simply stock, the back portion of which is also known as a shoulder stock, a buttstock or simply a butt, is a part of a long gun that provides structural support, to which the barrel, action, and firing mechanism are attached. The stock also provides a means for the shooter to firmly brace the gun and easily aim with stability by being held against the user's shoulder when shooting the gun, and helps to counter muzzle rise by transmitting recoil straight into the shooter's body. The tiller of a crossbow is functionally the equivalent of the stock on a gun. History and etymology The term stock in reference to firearms dates to 1571 is derived from the Germanic word ''Stock'', meaning tree trunk, referring to the wooden nature of the gunstock. Early hand cannons used a simple stick fitted into a socket in the breech end to provide a handle. The modern gunstock shape began to evolve with the introduction of the arquebus, a matchlock with a longer barrel a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
