The entire idea behindthe CheyTac LRRS (Long Range Rifle System) is to provide long range soft target interdiction (read: anti-personnel sniper) rifle package, with maximum effective range, but relatively compact and light. To achieve this goal, the professor John D. Taylor designed
the.408CheyTac cartridge. Being mid-way in size between the mighty .50BMG and
already established long-range
favorite .338Lapua, the .408 features a streamlined bullet with advanced patented design. This design allows the standard 419
grain (27.15gram) bullet to retain its supersonic velocity at the ranges beyond 2000 meters (2200 yards). At the ranges beyond 700 meters the .408 bullet has more
energythan the standard .50BMG ball bullet.
The .408 cartridge also is lighter than.50BMG cartridge by about 1/3, and generates less recoil.
The original CheyTac Intervention M100 rifle is based on the Windrunner .50 caliber take down rifle from EDM Arms. Current
Intervention M200 sniper rifles still are based on Wind runner design, but with several modifications.The Long Range Rifle System also includes CheyTac tactical computer (commercial PDA with CheyTac ballistic software), Nightforce NXS 5.5-22X
scope, and Kestrel 4000 wind/temperature/
atmospheric pressure sensors, linked to the PDA. The Tactical Computer with sensors and internal ballistic database provides all necessary data for long range fire.
CheyTac papers state that:The entire System is capable to deliver sub-MOA accuracy at the ranges of up to 2500 yards (2270 meters).
The Intervention M200 is a manually operated, rotating bolt rifle. The retractable butt stock allows for adjustment of the length of pull, and can be fully collapsed for storage and transportation. The barrel can be quickly removed for replacement, or storage and transportation. The butt contains integral real monopod, which is hinged,and can be folded up when not in use. The heavy, fluted barrel is free floated,and its rear part is
enclosed by tubular shroud, which serves as a mount for integral folding bipod and carrying handle. Barrel is provided with effective muzzle brake, which can be
replaced with OPSINC suppressor (silencer).
M200rifle is fed using detachable single stack magazines, which hold 5 rounds.Topo f receiver is fitted with permanent
MilStd Picatinny rail. Standard scope is Nightforce NXS 5.5-22X, which can be upgraded with AN/PVS-14 Night Vision
moduleand AN/PEQ-2 IR laser. No iron sights are provided with M200 rifle.
CheyTac Associates also offers a less expensive, non-takedown single shot rifle in .408caliber, the Intervention M310. This
bolt action rifle with adjustable
polymerstock is suitable for long range sport shooting, as well as for police longrange snipers.
