The M24 Remington Bolt Action Rifle has been the standard in accuracy and reliability for the US Army since 1998. Consistently delivering sub MOA performance on demand, the M24 is 43" overall length is very much, a traditional sniper rifle.
Today, more than half the world's population lives in urban spaces. Drawn by economic opportunities, social connectivity, infrastructure and better standards of living, the useable landmass of these metro areas can only support so many people giving rise to a sprawl of smaller cities, suburbs and slums, often built directly adjacent to the primary area. Built specifically around zero fail
missions in these settings, we needed a sniper rifle that was maneuverable and could be end user carries with a reduced signature.
At first, we explored gas guns. While making excellent battle rifles, a gas gun, no matter the tolerances, cannot predictably deliver the pronounced accuracy of a bolt gun.
From the ground up, the receiver on AR10 pattern rifles simply does not have the mass to retain a heavy contour precision barrel in a predictable position after it settles from a shot. Also, while tight chambers improved accuracy on manually fed bolt guns, in practice, they caused reliability issues when magazine fed by a gas or piston weapon system because, even 95% performance is not 100% of the time.
Built for the M118LR round, we started with the Surgeon 591 SA(Short Action) and a 16" 308 barrel. This "short" barrel would make the weapon system easier to maneuver and could be removed to further reduce the end user's profile. The barrel could then replaced with zero effect to the 1/2 inch groups the CSR consistently delivered, thanks to the tolerances Surgeon used/uses in manufacturing their barrels.
Housing the Surgeon action and barrel, is a Remington Accessory Chassis System (RACS). Not only the lighter than other rifle chassis, it is one of the fastest to break down and set up, with only 3 bolts needed to remove the handguard. The free float handguard is modular, allowing user configuration to keep the weapon as light as possible and features wire channels and plugs to route and manage cables.
The RACS also features a skeletonized folding stock with adjustment in the recoil pad and cheek height to support a range of scopes with bells and objective lenses of varying size. Stock folded, it can be fit into a normal sized bag, something seen in every day life, and still be immediately accessible to the end user if the situation dictated. That put a 800 meter gun in a day pack. A capability unlike any other at that point in time.
Fully loaded, the CSR is about the size of a M4. It can be maneuvered quickly through doors, windows, alleys, ladders, and hallways without encumbering the end user. It can live alongside of a carbine in a vehicle, meaning it can go everywhere and be deployed at the same speed as a carbine.
Today, the CSR is employed by law enforcement and security professionals in the exact settings and mission it was designed for. It is second to none.
