The XM2010 Sniper Weapon System is a sniper rifle developed by PEO Soldier for the U.S. Army. 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.[1][2]

Design

The 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 7.62x51mm NATO chambered M24 rifles are:[3]

  • Rechambering to .300 Winchester Magnum.
  • Rebarreling to a 610 mm (24 in) long, 254 mm (1 in 10 inch) twist rate (5R) 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 5-round detachable box magazine.
  • Fitting a quick-attachable/detachable Advanced Armament Corp. sound suppressor with muzzle brake to reduce audible and visible signature with an available thermal sleeve that reduces mirage effect on heated suppressors.[4]
  • Fitting a Leupold Mark 4 6.5-20x50mm 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,[5] fielded with the AN/PVS-29 Clip-on Sniper Night Sight.[6]
  • 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.

Ammunition

Project manager Douglas Tamilio with XM2010

In 2009 the US government purchased MK 248 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 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 defection on bullets in flight and use a reduced muzzle flash propellant that remains temperature stable across an operational temperature range of -32 °C tot 74 °C (-25 °F to 165 °F).[7][8][9] According to JBM Ballistics,[10] 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).
