XM2010 Enhanced Sniper Rifle

The XM2010 Enhanced Sniper Rifle (ESR), formerly known as the M24 Reconfigured Sniper Weapon System, is a sniper rifle developed by PEO Soldier for the U.S. Army.[2] It is derived from the M24 Sniper Weapon System and is intended to replace existing M24s. After winning a competitive bidding process, Remington was awarded the production contract. Up to 3,600 weapons will be procured. The Army expects to begin fielding 250 upgraded weapons to deployed U.S. Army Snipers by the end of December 2010.[3][4] Later project manager for Soldier weapons Colonel Douglas Tamilio said the XM2010 expected fielding will happen in January 2011.[1]

The major configuration change for the XM2010 system is the conversion from 7.62x51mm NATO to more powerful .300 Winchester Magnum ammunition to provide approximately 50% additional effective range. This rechambering to dimensionally larger cartridges is possible since the M24 was designed to use the "long-action" version of the Remington 700 receiver. The US Army hopes that the additional effective range helps their snipers in engagements in mountainous and desert terrain in which the War in Afghanistan is fought.[5] The general penalties for using bigger more powerful magnum rifle ammunition compared to smaller non-magnum standard rifle cartridges to obtain extra effective range are increases in recoil, jump, flash and barrel wear.

DesignThe XM2010 is considered a "total conversion upgrade", by which the chambering, barrel, stock, magazines, muzzlebrake, suppressor, and even the optics will be changed. The main reconfiguration changes compared to 7.62×51mm NATO chambered M24 rifles are:[6]

Rechambering to .300 Winchester Magnum.
Rebarreling to a 610 mm (24 in) long, 254 mm (1 in 10 inch) twist rate (using Obermeyer 5-R rifling) hammer-forged free floating barrel.
Fitting a new chassis (stock) assembly, which maximizes the amount of physical adjustments for the sniper to provide a better user customized fit. The chassis has a folding buttstock that shortens the system for easier transport and better concealment during movement and accommodates the mounting of accessories via removable Mil Std 1913 Picatinny Rails.
Fitting a five-round detachable box magazine.
Fitting a quick-attachable/detachable Advanced Armament Corp. sound suppressor with muzzle brake to reduce recoil and jump and audible and visible signature with an available thermal sleeve that reduces mirage effect on heated suppressors.[7]
Fitting a Leupold Mark 4 6.5–20×50mm ER/T M5 Front Focal variable power telescopic sight featuring a 34 mm tube diameter, first focal plane Horus Vision grid system range estimation reticle and Bullet Drop Compensation,[8] fielded with the AN/PVS-29 Clip-on Sniper Night Sight.[9]
Applying advanced corrosion resistant coatings throughout the system.
According to Remington Arms each rifle is tested to meet (and typically exceeds) the requirement to fire ≤ 1 MOA (less than a 2-inch shot group at 200 yards) before being released for fielding.

[edit] Ammunition
Project manager Colonel Douglas Tamilio with XM2010In 2009 the US government purchased MK 248 MOD 0 and MOD 1 .300 Winchester Magnum match-grade ammunition for use in .300 Winchester Magnum sniper rifles like the U.S. Navy Mk.13 SWS or reconfigured M24 SWS's. This ammunition was developed as a .300 Winchester Magnum Match Product Improvement (PIP) and uses the (190 gr) and 14.26 g (220 gr) Sierra MatchKing Hollow Point Boat Tail (HPBT) very-low-drag bullet fired at a nominal muzzle velocity of 869 m/s (2,850 ft/s) ± 15.2 m/s (50 ft/s). According to the U.S. Navy this ammunition should increase the maximum effective range of .300 Winchester Magnum sniper rifle systems to 1,370 m (1,500 yd), decrease wind deflection on bullets in flight and use a reduced muzzle flash propellant that remains temperature stable across an operational temperature range of -32 °C to 74 °C (-25 °F to 165 °F).[10][11][12] According to JBM Ballistics,[13] using the G7 ballistic coefficient provided by Bryan Litz, the Mk 248 MOD 1 .300 Winchester Magnum cartridge, when fired at its nominal muzzle velocity of 869 m/s (2,850 ft/s), should have approximately 1,286 m (1,406 yd) supersonic range under International Standard Atmosphere conditions at sea level (air density ρ = 1.225 kg/m3).

Parece un arma de Gijoe Quiero refpic xD

Ahi esta!

Don Fusco!

Buena caza tio!

Gracias!

Quiero su replica de airsoft!!

Por cierto, mi mk18 ya esta a full, solo falta darle una manita de pintura, a ver si Doc da señales de vida humana!

He conseguido algunas cosillas interesantes... CAT original y Mitch 2000 original... impresionante!!.
