Innomount build German quick-release and fixed mounts. The range is organised by base (Weaver/Picatinny or Tikka T3), ring size and height, and you need all three right.
Working out the height. Measure the objective bell diameter, halve it, and add clearance to the top of the base - then check the bolt handle clears on the way up. Heights here run 14mm, 17mm, 19mm, 20mm, 22mm and 27mm. Mount as low as the objective allows: every millimetre of extra height is more hold-under at close range and a worse cheek weld. If you have to go high to clear a 56mm objective, budget for a cheek riser as well.
One piece or two. One-piece mounts hold alignment for you and suit a flat-top action; two-piece are lighter and give clearance for loading a magnum action through the port. Tikka T3 bases are cut for Tikka's own dovetail and will not sit on a Picatinny rail - the two are not interchangeable, and this is the single most common ordering mistake on this page.
Thermal and clip-on. The zero mounts take 30mm tube digital and thermal units on Picatinny. If you are swapping a clip-on between rifles, the QR is what makes that practical - it returns close enough to zero to be worth checking rather than re-zeroing.
