The Boyd stock I got formy mountain rifle fit fine, didn't have to have it free floated. It shoots great in that stock. The magnum model sevens had 22" the standard newer model sevens have 20" barrels. Call them they should know if it will work they were helpful when I had questions before I ordered. Gandermountain in york pa had probably 10 remington 700 adl combos in 243 and a couple in 223 for $480. I got 13 rem 700 and one model seven.
