Designated Marksman Rifle
A designated marksman rifle (DMR) is a modern telescopic sight, scoped high-Accuracy and precision, precision rifle used by infantry in the designated marksman (DM) role. It generally fills the engagement effective range, range gap between a service rifle and a dedicated sniper rifle, at around . DMRs are distinguished from sniper rifles in that they are semi-automatic rifle, semi-automatic to provide higher rate of fire, rates of fire (with some also having selective fire to switch to Burst mode (weapons), burst or Automatic firearm, automatic) and have larger magazine (firearms), magazine capacities (10, 20, or 30 rounds depending on the firearm and operational requirements) to allow rapid engagement of multiple targets. DMRs have to be effective, in terms of probability of kill, hit rates and terminal ballistics, at application ranges exceeding those of ordinary assault rifles and battle rifles, but do not require the extended-range performance of a dedicated sniper rifle.

Designated Marksman
A designated marksman (DM), squad advanced marksman (AD) or squad designated marksman (SDM) is a military marksman role in an infantry squad. The term ''sniper'' was used in Soviet doctrine although the soldiers using the Dragunov SVD were the first to use a specifically designed designated marksman rifle. The DM's role is to supplement the attached squad by providing accurate fire upon enemy targets at distances up to . Due to the need for repeated effective fire, the DM is usually equipped with a scoped semi-automatic rifle called a designated marksman rifle (DMR). Like snipers, DMs are trained in scouting and precise shooting, but unlike the more specialized "true" sniper (who often operate independently), they operate as an intrinsic part of an infantry fireteam and are tasked to lay down accurate support fire at valuable targets as per tactical necessity, thus extending the reach of the fireteam. The growth of the DM rifle can be attributed to two main influences; the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Picatinny Rail
The 1913 rail (MIL-STD-1913 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 telescopic sights atop the receivers of larger caliber rifles. Once established as United States Military Standard, its use expanded to also attaching other accessories, such as: iron sights, tactical lights, laser sights, 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. History Attempts to standardize the Weaver rail mount designs date from work by the A.R.M.S. company and Richard Swanson in the early 1980s. Specifications for the M16A2E4 rifle and the M4E1 carbine received type classification generic in December 1994. These were the M16A2 and the M4 modified wi ...

Pistol Grip
On a firearm or other tools, a pistol grip is a distinctly protruded handle underneath the main mechanism, to be held by the user's hand at a more vertical (and thus more ergonomic) angle, similar to how one would hold a conventional pistol. In firearms, the pistol grip is located behind the trigger (firearms), trigger and generally held by the hand that operates the trigger. Rifles and shotguns without pistol grips are generally referred to as having "straight" or "upland" (shotguns only) style stock (firearms), stocks. Some firearms, starting from a 1840s Belgian carbine, and some automatic weapons in the 20th century (e. g., Chauchat MG, Thompson submachine gun, Thompson submachine gun, AK-47 assault rifle), have a second vertical forward grip, frontal pistol grip (or foregrip) on the firearm's forearm (firearm component), fore-end to be used by the support hand for better stability in operation. Pistol grips can also serve multiple functions, such as a magazine (firearm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

M40 Rifle
The M40 rifle is a bolt-action sniper rifle used by the United States Marine Corps. It has had four variants: the M40, M40A1, M40A3, and M40A5. The M40 was introduced in 1966. The changeover to the A1 model was completed in the 1970s, the A3 in the 2000s, and the A5 in 2009. Each M40 is built from a Remington Model 700 bolt-action rifle, and is modified by USMC armorers at Marine Corps Base Quantico, using components from a number of suppliers. New M40A5s are being built, and A1s are upgraded to A3s and A5s as they rotate into the armory for service and repair. The rifles have had many sub-variations in telescopic sights, and smaller user modifications. The M40A5 incorporates a detachable magazine and a threaded barrel to allow for the use of a sound suppressor or another muzzle device. The original M40 was a military type-classified version of the Remington 700; it was factory-made, and had a one-piece wooden Stock (firearms), stock. The M40A1 and A3 switched to fiberglass ...
