10 Best Sniper Rifles

1. M24 Sniper Weapons System (U.S.A)
PEO M24 SWS.jpg
The M24 (SWS) is the military and police version of the Remington 700 rifle, M24 being the model name assigned by the U.S. Army after adoption as their standard sniper rifle in 1988. The M24 is referred to as a “weapons system” because it consists of not only a rifle, but also a detachable telescopic sight and other accessories. The M24 SWS has the “long-action” bolt version of the Remington 700 receiver but is chambered for the 7.62x51mm NATO “short-action” cartridge. The “long-action” allows the rifle to be re-configured for a dimensionally larger cartridge. 

2. Knight’s Armament Company SR-25 (U.S.A)

The SR-25 (Stoner Rifle-25) is a semi-automatic special application sniper rifle designed by Eugene Stoner and manufactured by Knight’s Armament Company. The SR-25 uses a rotating bolt and a direct impingement gas system. It is loosely based on Stoner’s AR-10, rebuilt in its original 7.62x51mm NATO caliber. Up to 60% of parts of the SR-25 are interchangeable with the AR-15 and M16 - everything but the upper and lower receivers, the hammer, the barrel assembly and the bolt carrier group. SR-25 barrels were originally manufactured by Remington Arms with its 5R (5 grooves, rounded) rifling, with twist 1:11.25 (1 complete turn in 11.25 inches or 286 millimetres). The heavy 20 in (510mm) barrel is free-floating, so handguards are attached to the front of the receiver and do not touch the barrel.

3. L42A1 Enfield (U.K.)
L42A1 Sniper Rifle
The L42A1 was a British Army sniper rifle chambered for the 7.62mm NATO cartridge which entered service in 1970. It served until replacement by the Accuracy International L96 in 1985. It was the last model in a long and famous line of Lee bolt action rifles using the rear-locking action designed by James Paris Lee to serve the British Army, which had first entered service in the Lee-Metford rifle of 1888. During its British Army service, the L42A1 saw active service during several conflicts including the Dhofar Rebellion in Oman, The Troubles in Northern Ireland, the Falklands War and Gulf War.

4. M21 (U.S.A.)

The M21 Sniper Weapon System (SWS) is the semi-automatic sniper rifle adaptation of the M14 rifle. It is chambered for the 7.62x51mm NATO cartridge. The United States Army wanted an accurate sniper rifle during the Vietnam War. The M14 was selected because of its accuracy, reliability, and the ability for a quick follow up shot. As a result, in 1969, the Rock Island Arsenal converted 1,435 National Match (target grade) M14s by adding a Leatherwood 3-9x Adjustable Ranging Telescope and providing National Match grade ammunition. This version, called the XM21, had a specially selected walnut stock and was first fielded in the second half of 1969. An improved version with a fiberglass stock was designated the M21 in 1975. The M21 remained the Army’s primary sniper rifle until 1988, when it was replaced by the M24 Sniper Weapon System; some M21s were later re-issued and used in the Iraq War.

5. Heckler & Koch PSG1 (Germany)

The PSG1 (“precision shooter rifle”) is a semi-automatic sniper rifle. The PSG1 is mechanically based on the G3 rifle and features a low-noise bolt closing device (similar to the forward assist on many M16 rifles). Its shot-to-shot variation is expected to be better than 1 minute of angle (MOA) with match ammunition. Although this level of accuracy is unremarkable in modern semi-automatic rifles, it was claimed that the PSG1 was “one of the most accurate semi-automatic sniper rifles in the world.” PSG1s are not supplied with iron sights but come equipped with the Hensoldt ZF6x42PSG1 scope with an illuminated reticle. The scope has a built-in range adjustment feature which can be adjusted from 100 to 600 m. It has a heavy free-floating barrel with polygonal rifling and an adjustable stock.

6. Dragunov SVD (Soviet Union)

The Dragunov sniper rifle (“Sniper Rifle, System of Dragunov, Model of the Year 1963”) is a semi-automatic sniper/designated marksman rifle chambered in 7.62x54mmR and developed in the Soviet Union.The Dragunov was designed as a squad support weapon since, according to Soviet and Soviet-derived military doctrines, the long-range engagement ability was lost to ordinary troops when submachine guns and assault rifles (which are optimized for close-range and medium-range, rapid-fire combat) were adopted. For that reason, it was originally named “Self-Loading Rifle, System of Dragunov, Model of the Year 1963.”

7. Accuracy International AS50 (U.K.)

The AS50 is a .50 BMG sniper/anti-materiel rifle manufactured by British firearms producer Accuracy International. The AS50 enables operators to engage targets at very long range with high accuracy using explosive or incendiary ammunition. The AS50 employs a gas operated semi-automatic action and muzzle brake, allowing for lower recoil than the AW50 bolt action rifle and faster target acquisition. The rifle is highly transportable, ergonomic and lightweight. It can be disassembled in less than three minutes and serviced without tools. The AS50 is designed for the British Armed Forces and United States Navy SEALs, the rifle is employed due to its high rate of fire (five rounds in 1.6 seconds). This high rate of fire is due mostly to the floating barrel and the lightweight titanium frame.

8. CheyTac Intervention .408 (U.S.A.)

The CheyTac Intervention an American bolt action sniper rifle manufactured by CheyTac LLC. It is fed by a 7-round detachable single stack magazine. It fires .408 Chey Tac or .375 Chey Tac ammunition. CheyTac LLC states that the system is capable of delivering sub-MOA accuracy at ranges of up to 2,500 yards (2,300 m), one of the longest ranges of all modern-day sniper rifles. It is based on the EDM Arms Windrunner. The Intervention holds the world record for best group at a distance, landing 3 bullets within 16-5/8 inches at 2,321 yards near Arco in Idaho. On the Discovery Channel TV show Future Weapons, the April 9, 2007 episode “Massive Attack’ the host Richard Machowicz, a former United States Navy SEAL, made 3 out of 6 shots, hitting a human-sized sheet of metal at a distance of 2,530 yards at Arco Pass in Idaho. CheyTac states that “the CheyTac LRRS is a solid anti-personnel system to 2,000 yards.”

9. Accuracy International L115A3 AWM (U.K.)

Designated L115A3 AWM (Arctic Warfare Magnum) is a bolt-action sniper rifle manufactured by Accuracy International designed for magnum rifle cartridge chamberings. The Accuracy International AWM is also unofficially known as the AWSM (Arctic Warfare Super Magnum), which typically denotes AWM rifles chambered in .338 Lapua Magnum. In November 2009, British Army sniper Corporal of Horse (CoH) Craig Harrison, a member of the Household Cavalry, set the current record for longest recorded sniper kill by killing two Taliban machine gunners consecutively south of Musa Qala in Helmand Province in Afghanistan at a range of 2,707 yards using a L115A3 Long Range Rifle.

10. Barrett M82 (U.S.A.)

The M82, standardized by the US Military as the M107, is a recoil-operated, semi-automatic anti-materiel rifle developed by the American Barrett Firearms Manufacturing company. Designated as a heavy SASR (Special Application Scoped Rifle), it is used by many units and armies around the world. It is also called the “Light Fifty” for its .50 BMG (12.7x99mm NATO) chambering. The weapon is found in two variants, the original M82A1 (and A3) and the bullpup M82A2. The M82A2 is no longer manufactured, though the XM500 can be seen as its successor. The M82 is a short recoil semi-automatic firearm. When the gun is fired, the barrel initially recoils for a short distance, before being securely locked by the rotating bolt.
