HOW TO CHOOSE THE CORRECT MOUNT We have the world's most comprehensive line of tactical scope mounts; it currently spans about 90 different models of various heights, tilts, lengths and ring dimensions. We have therefore compiled this short guide to help you choose the right mount for your needs. Picatinny or direct mount? The first obvious question is if the mount should be a Picatinny mount (models beginning with SP or QDP) or a direct attachment mount such as our line of ISMS mounts for Accuracy International (SA,) Sako TRG/Tikka T3 (ST,) and Sauer STR (SS.) The main reason for using a direct mount is to allow a stronger and lower positioning of the rifle scope. If there’s no other need for a Picatinny rail we generally recommend direct mounts on these rifles.
