yes as long as the Remington model 700 sps is chambered for 308 Win.
Since 1921 Remington has date stamped the barrel you can find the details/table on the Remington Society of America under the Manufactured Date link.
What I have found is its 1-10" for 308.
If its a .308 its a short action.
If you can find a Remington Sportsman 78 for less than $300 and it is in good condition buy as many as you can. $400 - $500 would be fair.
There is no such model.
