Weaver makes an extended rail. I've got it on my 110 Long 30-06 Accu round back. Not sure that it's much longer as far as amount of slots though?
Be careful not to get too long of a rail! I battled with 3 sets of rings of various heights to finally get eye relief and clearance correct. Of course, if your rings are a mile high, then it wouldn't matter how long the rail as long at the eyepiece and obj bells clear it...
