m40a3


Match-Grade Ammunition

  • 7.62 x 51mm M118 Match Grade A 173-grain round.
  • Development of the M40A3 began in 1996, and the final product was revealed in 2001.[4] Since then, numerous minor changes have occurred to the platform. It is highly possible that more changes will occur to the platform as it gains operational use in Iraq and Afghanistan. Listed here is the latest configuration known to be used in an M40A3.

    Action: The M40 has always been based on the proven Remington 700 Short Action and this is no different in the M40A3.[5] These actions are all chambered in 7.62 mm NATO and are house tuned by Marine armorers; the trigger guard assembly is manufactured by the DD Ross Company, though several M40A3s use Badger Ordnance trigger guards.[4] In 2007, the Marine Corps began replacing the DD Ross trigger guard assemblies with the M5 detachable magazine trigger guard manufactured by Badger Ordnance.[5]

    Barrel: The barrel is a Schneider 610 /24-inch, 6-groove, 1:12" match-grade heavy barrel.[5][6]

    Stock: All service M40A3s are based upon the A4 Tactical Riflestock, a high-quality benchrest-style fiberglass riflestock made by McMillan Fiberglass Stocks and cast molded in an OD Green color.[4][6] The action is glass bedded into the stock with aluminum pillars, while the barrel is allowed to "float" (it is attached only to the action), ensuring maximum accuracy. The stock has adjustable length-of-pull (through a buttstock spacer system) and a Marine manufactured adjustable saddle-type cheekpiece.[6] The stock also has six mount flush cups, two on each side front and back and one each on the front and rear underside.[4] One bipod stud is located on the underside of the forearm.[6]

    Sling: The Model 1907 sling that has been historically used on M40A3s has been replaced with the Quick Cuff Model Two sling manufactured by Tactical Intervention Specialists.

    Bipod: The M40A3s use a 6–9" Harris notched swivel type bipod with a KMW podlock.[6] The QD bipod attaching screw is replaced with a screw made by Jon Tank of Tanks Rifle Shop.

    Dayscope: A modified Schmidt & Bender 3–12× 50 Police Marksman II LP rifle scope with illuminated reticle has replaced the Unertl MST-100 10× fixed day scope, previously used on both the M40A1 and M40A3.[6] This dayscope is mounted with Badger Ordnance USMC M40A3 34mm scope rings, which utilize a standard ring in the rear and a wider MAX-50 ring in front.[4] The standard front ring cap is replaced with a SPA-Defense B634 34mm Male Dovetail, as a mounting platform for the Simrad KN200 Night Vision Weapon Sight. The scope and rings are mounted on a DD Ross 30 minute-of-angle lugged Picatinny rail.[4][5]

Mk 12-special purpose rifle

 

Specifications

  • Barrel: An 18-inch (457 mm) threaded-muzzle match-grade free floating stainless steel heavy barrel with a 1:7 (178 mm) rifling twist ratio is standard for the SPR. The barrels are manufactured by Douglas Barrels with a special contour to maximize accuracy and to minimize weight. An OPS Inc. muzzle brake and collar (to align the OPS Inc. 12th Model Suppressor) is installed with the barrel. These barrels were designed to take advantage of the new Mk 262 cartridge, which uses a 77-grain (5 g) bullet.
  • Buttstock: SPRs have been seen with M16A1 or M16A2 fixed buttstocks, telescoping M4 buttstocks, and the Crane Enhanced telescoping buttstock. The rifles are compatible with any type of stock system developed for the M16.
  • Handguards: In all cases a free-floating forearm is used, which does not touch the barrel directly. This increases the accuracy of the weapon by removing vibration and pressure exerted on the barrel by the rest of the gun. The first SPRs used PRI Gen I or Gen II carbon-fiber free-float tubes. The SPR/A, SPR/B, and Mk 12 Mod 1 all use the Knights Armament Company M4 Match Free-Floating Rail Adapter System. The Mk 12 Mod 0 uses PRI Gen III free-float tubes. The Gen I and Gen II Freefloat Forearms are combined with the Atlantic Research Marketing Systems #38 SPR MOD Sleeve, while the Gen III Freefloat Forearm, due to its it larger barrel nut, only works with the ARMS #38 SPR PEQ-2-3.
  • Sights: The original SPR used an early PRI flip-up front sight with an elevation dial, which has since been discontinued. The Mk 12 Mod 0 uses the current PRI flip-up front sight. The SPR/A, SPR/B, and Mk 12 Mod 1 use the KAC rail foreend flip-up front sight. The SPR and Mk 12 Mod 0 use the ARMS #40 flip up rear sight. The rest of the models use the KAC 600 meter flip up rear.
  • Optics: Due to the relative modularity of the system, optics (as well as almost everything else) can be mounted according to the operator's wishes. However, SPRs are most often seen with a 3.5–10×40 mm Leupold LR M3 (SPR/A), a 2.5–9×36 mm TS-30 (SPR/B), or a 3–9×36 mm TS-30 A2 (Mk 12 Mod 0/1) Mid Range/Tactical Illuminated Reticle Dayscope. Night vision devices can also be attached. These scopes usually come with flip open dust covers and a honeycomb anti-glare anti-reflection device. Given Nightforce Optics' NAVSPECWAR contract, it is believed that many NAVSPECWAR issued SPRs will use the Nightforce 2.5-10x24 NXS scope.[3]
  • Suppressor: The OPS Inc. 12th Model SPR Muzzle Brake Suppressor threads directly onto the OPS Inc. muzzle brake and uses the collar to stay centered.
  • Ammunition: 20rd mag's or 30's (Arma2 only)

m24 sniper weapon system

 

Sights: Leupold Ultra M3 10 x 40mm fixed power, Leupold Ultra M3A 10 x 40mm fixed power, or Leupold Mk.4 LR/T M3 10 x 40mm fixed power scope. Detachable emergency Redfield-Palma International back-up iron sights, fitted with tabs that fit into slots machined into the front and back of the barrel.

Barrel: Free-floating; made of 416R Stainless Steel. The bore twist is 1-turn-in-11.25 inches [1:285.75 mm] and the rifling is 5 radial lands and grooves (5-R) with a right-hand (RH) twist.

Stock: H-S Precision PST-11 stock. The stock secures the barrel via an aluminum bedding block to keep it rigid. A twin-strut extension that pulls out of the butt is adjustable for a 2-inch [50.8mm] length-of-pull. This is effected by a thick wheel on a central grooved pillar for adjusting the length and a thin locking ring behind it locks the thick wheel in place. The latter is notorious for failing, causing the extension to slide back and forth. Also a styrofoam core designed to reduce the stock's weight would absorb water if it was carried in the rain or soaked in a stream or river, making the weapon heavy and unbalanced.

Accuracy: According to MIL-R-71126(AR), the M24 shall achieve the accuracy results stated below when using M118 Special Ball and fired from a Government approved machine rest. The average mean radius shall be less than or equal to the following values:[3]

  • 200 yards [182.8 meters]: 1.3 inches
  • 218.7 yards [200 meters]: 1.4 inches
  • 300 yards [274.3 meters]: 1.9 inches

Maximum effective range is given as 874 yards [800 meters], but record shots have been made with the M24 at 1,000+ meters.
