You might try burrisoptics.com. They have a pretty complete website with FAQs and an e-mail contact setup. With the dovetail type mount, if you know scope eye relief and how much working space you have between the power adjustment ring and the adjustment turret you can figure whether extension rings are necessary. As for action length, a two piece mount would resolve that if the one piece wouldn't fit. Then your only problem is what ring height to get. midwayusa.com probably has information on Burris ring heights or Burris could supply that info. Good luck.
