I know this might be a long shot but I am looking for anyone that might have a model 99 using a SPUHR sp4003b mount with a us optics 5-25x58. As the 99 comes with a 27 MOA rail and the SPUHR for this model of scope comes in one height (38mm), I calculate that it should fit on principle of height measurements; however, I wonder if I will have issues with a 27 MOA rail on the far end with an 18" optic. The pitch of the rail drops from (roughly) 12.7mm down to 10.4mm on the far end and I imagine I will have 8+ inches of scope after the end of the rail.
