This conversion kit can be changed out in less than 60 seconds in the field with a 5mm allen wrench. The kit includes barrel, bolt, magazine and bolt stop for short bolt throw. The 338 Lapua Magnum is the ultimate sniping cartridge because it has a trajectory and effective range that rival the powerful 50 BMG, at less than half the weight. The SRS 338LM is over 20 inches shorter and weighs just 12 lbs and has proven to be very effective out to 1800 meters. The SRS is the shortest purpose built sniper weapon in the world! The SRS is almost a foot shorter than conventional sniper weapons because it utilizes a bullpup configuration as well as a collapsible bolt design. The compact design shifts the weight reearward, creating not only a shorter weapon, but also a perfectly balanced rifle.

The SRS was designed to operate under the harshest conditions and abuse. It utilizes high-impact polymers, aircraft grade aluminums (7075-T6), ultra high-strength steels, and the strongest coatings known to man. The operating mechanisms are completely encased by the stock panels except for the ejection port area. The stock panels attach directly to the receiver which acts as a full length mounting chassis, eliminating the need for any sort of bedding interface. The SRS sustains its accuracy and reliability in virtually any environment, including: arctic subzero temperatures, extreme heat and dust of the desert, and wet jungle environments.

Other Features:
SRS magazines incorporate a "shoulder retention" feature that prevents the projectile tips from slamming into the front of the magazine during recoil. In traditional magazines the projectile tips slam against the front of the magazine, deforming the projectile, and in turn diminishing accuracy. This cannot happen with our magazines. In addition, our internal magazine length is a healthy 4" long which is .4" longer than comparible magazines, making it possible to load the 300+ grain bullets to their maximum.

CheyTac L.L.C researched the optimum cartridge case, bullet and barrel configuration for very long range use. For this the .408 Chey Tac cartridge was developed that fires very-low-drag mono metal bullets that were specially designed for the Long Range Rifle System by the now (2010) defunct company, Lost River Ballistic Technologies.
Lost River Ballistic Technologies inventor, Mr. Warren Jensen, stated that "the .408 Chey Tac was the first bullet/rifle system that utilizes a balanced flight projectile. To achieve balanced flight the linear drag has to be balanced with the rotational drag to keep the very fine nose (meplat) of the bullet pointed directly into the oncoming air. It should result in very little precession and yaw at extreme range and allows accurate flight back through the transonic region. This is hard to achieve for small arms projectiles. Mathematically you are at a great disadvantage trying to achieve balanced flight with a lead core non mono metal bullet. The rotational mass/surface area ratio is too high."
The balanced flight projectile patent can be found at the US Patent Office, Controlled spin projectile, US PAT No. 6,629,669. According to the patent, a projectile engraved and launched according to the specifications of the patented invention should decelerate from supersonic flight through transonic to subsonic in a stable and predictable manner effective to a range beyond 3,000 yards (2,743 m). It implies that, amongst several other preconditions, the rifle barrel has to have specific rifling dimensions to achieve a desired amount of axial air drag on the bullet's surface, which reduces the bullet's spinrate to achieve balanced flight.
To achieve balanced flight the rifling twist rate for the .408 CheyTac chambering was chosen at 330.2 mm (1 in 13 in), with eight 0.4080 in diameter grooves, 0.4010 in diameter bore and a 0.050" land width, square cut, with no taper. The later .375 CheyTac round, developed from the .408 CheyTac, uses a 292 mm (1:11.5 in) rifling twist rate.

The United States Navy Mark 14 Enhanced Battle rifle (EBR) is an American selective fire military rifle chambered for the 7.62x51mm NATO cartridge. It is a variant of the M14 battle rifle and was originally built for use with units of the United States Naval Special Warfare Command, such as the United States Navy SEALs. The EBRs are made with the intention of carrying out both designated marksman and CQB roles in combat. Since 2010, the U.S. Army has made available two M14EBR-RI rifles per infantry squad for units deploying to Afghanistan. The M14EBR-RI has a standard weight 22.0" barrel and lugged GI flash hider, it is not to be confused with the MK14 Mod 0 or Mod 1.
Several configurations are allowed on the Mark 14 Mod 0 rifle, among them include the attachment of the AN/PVS-4 night vision scope. Others had included the capability of adding two different scopes/sights on the Picatinny rails, for more precision or zoom level.

Barrett engineers began designing the M98B in 1997, with a goal of developing a precision tactical .338 Lapua rifle not based on any sporting rifles. The initial semi-auto design, the Model 98 was unveiled at the 1998 SHOT Show, but never went into full production. In recent years, Ronnie Barrett's son, Chris, revived the company's interest in the .338 rifle.
Many of the M98B's features are inspired by Stoner's AR-15/M16; the hinged aluminum upper and lower receivers, ergonomic pistol grip and thumb operated safety are all borrowed from Stoner's design. The upper receiver also features a full length (18.125 inches (460.4 mm)) 1913 style Picatinny rail for mounting optics, lasers, etc., and two additional accessory rails are mounted forward of the main rail on each side of the upper.
The M98B also features a fluted medium-heavy 27-inch (690 mm) barrel made of 4150 MIL-B-11595 steel. The barrel is rifled in a six groove, 1:10" right hand twist pattern, and features a two-port muzzle brake threaded on and indexed by a jam nut. The bolt rides in a new "bolt guide" design, consisting of two tubular glass-filled polymer guides which have been infused with Teflon. These guides allow the bolt to travel better, as well as reducing the need for lubrication, and helping to seal the ejection and bolt handle ports from dirt. The bolt head is made of case-hardened 8620 steel, features nine lugs (three sets of three), and is attached to the bolt body with a crosspin.This separate bolt head design allows for simple caliber changes, as well as future pre-headspaced barrel and bolt-head sets.
The lower receiver is forged from 7075 aluminum, can mount any type of AR-15/M-16 pistol grip, and features an ambidextrous magazine latch just forward of the integral trigger guard. Also featured within the lower receiver is the rifle's trigger assembly. The trigger assembly can be removed from the receiver as a single unit, and features adjustment screws for weight (2 to 4 lbs.) and overtravel, as well as a reversible AR-15/M-16 style thumb safety.
The skeletonized buttstock is also integral to the lower receiver, and features a thick Sorbothane buttpad with spacers for pull adjustment, a polymer cheekpiece with 0.75 inches (19 mm) of variable comb height, and an adjustable monopod.The rifle also comes from the factory with a Harris brand S-BR bipod attached to the fore-end.
The M98B was featured both on the cover, and in an article, of the April 2009 issue of American Rifleman magazine. Barrett's offering for USSOCOM Precision Sniper Rifle Contract the MRAD is derived from the M98B, changes include cutting back the fixed stock and intigrating a folding adjustable stock, a Desert Tan finish color, a front loading quick change barrel for caliber change although at this point the only offered barrel and caliber is a 24.5 inch fluted barrel with a 1 turn in 10 right hand twist chambered for .338 Lapua Magnum

REMINGTON MSR

A new level of surgical precision, the Remington Modular Sniper Rifle (MSR) was designed for operators by operators. It combines lethal accuracy at 1500 meters with a user adjustable folding stock, free-float handguard, and the potential to change barrel lengths and calibers within minutes at the user level from .338 Lapua Magnum to .300 Win Mag to 7.62 NATO. This patent-pending system addresses the long range and medium range needs of the modern battlefield in one package designed to meet multiple emerging US armed forces requirements. The MSR is mission-adaptable with just a change of the bolt face, barrel, and magazine, and features lightweight, efficient design and optimal material selection for performance and corrosion resistance – this system truly never has to leave the battlefield.
