Remington RACS vs Cadex

What is Remington RACS?

RACS is the acronym for the Remington Military “Remington Accessory Chassis System” . The Remington RACS was developed by a joint effort between Remington Military and Cadex Defence.

The patent pending Remington Accessory Chassis System (RACS) incorporates state-of-the-art operator-defined attributes such as a free-float tubular design and a fully featured front handguard section. Operator selectable auxiliary rail sections in various lengths can be attached to any of the seven remaining facets of the octagonal handguard, which allows the operator to install clip-on in-line night vision systems. The folding RACS buttstock provides the operator with a wide variety of adjustments to allow setting the system to suit the shooter and the operating conditions.

Now the above all sounds good right? Remington also refers to the RACS as “Remington Arms Chassis System” The Remington Military website uses both variations. It took me a few minutes to realize the difference

Observant shooters have noticed that the Remington RACS closely resembles Cadex Defense Chassis. This makes perfect sense. The Original Remington XM2010 was developed by a partnership between Remington Military and Cadex Defence.

What Cadex Chassis did the Remington XM2010 sniper rifle use? The Cadex Dual Strike is the closest match but not identical.

What’s Better Remington RACS or Cadex Dual Strike? Cadex has been upgrading the Dual Strike pretty regularly. At this time Cadex is on their 4th generation Dual Strike. Remington Military has made no publicly known changes to the RACS since release. While I can’t say first hand which is better but I will be putting my money down on the Cadex. The Cadex is also less expensive then the Remington.

Remington Defense Chassis System versus Remington Accessory Chassis System

The Remington Arms Chassis System refers to the Remington RACS on a complete Remington M2010/XM2010 ESR Enhanced Sniper Rifle when bought or fielded as a package.

The Remington Accessory Chassis System version of the RACS is how Remington Military refers to the RACS when purchased as an accessory and without a barreled action. Remington only list this as being available in sort action.

Now my take is the Remington Military website is simply out of date. EuroOptic list the RACS as being available in 300 Winchester Magnum, Remington 700 Long Action.

There are multiple versions of Remington RACS. The RACS chassis that is used in the XM2010, M2010 Sniper Rifle and the RACS chassis’s used in the Remington MSR, CSR and PSR Sniper Rifles.

Remington MSR, CSR and PSR RACS versus Cadex Chassis Systems

The Remington RACS Chassis in use on the Remington Defense Modular Sniper Rifle “MSR” and Remington Defense MK21 Precision Sniper Rifle “PSR” use a proprietary bolt action receiver and interchangeable barrels. This Remington RACS chassis in not compatible with any other receiver or barreled action. This RACS Chassis will not accept a Remington 700 receiver or barreled action.

The Remington RACS is only compatible with the Remington 700 and Remington 700 clone long and short actions. On the other hand the Cadex line of Chassis is compatible with the following brands of rifle actions (not all chassis, not all rifle models).
