Stevens Model 110E series K, .308

I have a Stevens Model 110E series K in .308. I am looking for a one piece 20 moa scope base to fit this rifle. Can someone please tell me what the action length is (short, long, or intermediate) and where I might find a base that will work? This is non-accutrigger model with flat rear receiver. Thanks, JD.

THat would be a long action flat back.

Well, the action might be considered intermediate, but I believe the hole spacing for the mount is the same.

What is the space, center to center, of the two inside screw holes?
