As long as the rifle has a barrel that is at least 16" (most people cut them 16.25" just for a small margin over minimum) *and* a minimum overall length of 26", you should be good to go.
I know of no state or federal laws that would prohibit this rifle. Adding any accessories such as a bipod to this set up should also pose no problem.
It would be very important to measure the barrel/bore length from the face to the bolt, with the bolt closed, to the muzzle.
