Remington 700 Footprint
Also: Rem 700 Footprint
The action dimensions of the Remington 700 that became the industry pattern for stocks, bases, and aftermarket actions.
The Remington 700 footprint refers to the external dimensions and mounting geometry of the Model 700 action: the round receiver profile, the screw spacing that holds it to the stock, and the related layout that the rifle made ubiquitous. Because the design was produced in such numbers for so long, its receiver shape became the reference point that the wider industry tooled up to match.
That standardization is why so much gear interchanges today. Stocks, a chassis, bottom metal, triggers, and a scope-base are routinely built to drop onto anything sharing this footprint, and many custom action makers copy those dimensions on purpose so buyers can use the deep aftermarket. For a precision builder, choosing a 700-footprint action opens the widest menu of parts.
