Here’s Rival Arms’ release about the new R-700 Precision Chassis System:

November 2020 (Dallas, TX) Recognized for premium aftermarket handgun and rifle components, Rival Arms® expands its offering of drop-in chassis systems with the new R-700 Precision Chassis for Remington® 700 rifles.

The R-700 chassis is designed to accept the Remington 700 short-action barreled action. The chassis is CNC-machined from aluminum billet and available in three finishes: Type III hardcoat anodize matte black (Item RA90RM01A), KG GunKote™ FDE (RM90RM01B), and KG GunKote Satin Gray (RA90RM01C).

Like the R-22 chassis developed for the Ruger® 10/22 barreled action (released by Rival Arms earlier this year), the R-700 is designed to accept AR-15 grips and buffer tube style buttstocks. This includes the Rival Arms ST-3X Precision Stock or any AR-15 stock that uses a 1-3/16″ 16 MILSPEC buffer tube. This versatility allows builders to add any buttstock that suites their needs, while also accommodating most A2 pattern pistol grips.

Precision inletting means the R-700 is a drop-in fit for factory Remington 700 short-action barreled actions and aftermarket precision actions. The forend/barrel channel delivers barrel free-float with all factory barrel contours and barrels up to one inch in diameter. Fourteen machined M-LOK® slots allow builders to install a broad range of readily available accessory mounts to adapt the chassis to any mission. The chassis also comes tapped with a sling swivel stud and is ergonomically designed with a scalloped forend for a positive grip when shooting without a rest.

MSRP for the new Rival Arms R-700 chassis is $381.99. The chassis is currently available on and starting to ship to dealers and distributors nationwide.
