Leupold QR 30mm Low Matte RingerDen store forskjellen mellom QR (Quick Release) og dual dovetail og STD systemet er QR systemets mulighet til å ta av og på kikkerten fra riflen uten at det påvirker presisjonen.Dette produktet anbefales til:40mm Objectiveswill almost always have enough clearance with LOW rings in a given style, though MEDIUM rings will give slightly more clearance, particularly when using a barrel with a thicker shank portion or a heavier contour.28-36mm Objectiveswill almost always use LOW rings in a given style. Again, in certain instances of a heavy barrel or heavy shank portion of a custom barrel, MEDIUM rings may have to be used, but LOW rings will almost always suffice.20-24mm Objectiveswill almost always be able to use LOW rings, but in some cases may also use SUPER LOW rings. In this instance, bolt handle clearance of the eyepiece will come into play more so than objective/barrel clearance and should be carefully considered.VX-3L 50mm Riflescopeswill almost always use LOW rings, but in some instances, where there is a very small barrel shank or relatively light barrel, they will be able to use SUPER LOW rings for the lowest practical mounting. Again, as in 20mm riflescopes, eyepiece versus bolt handle clearance will be more critical in many cases than objective/barrel clearance.VX-3L 56mm Riflescopeswill almost always use LOW rings, but in some instances, where there is a very pronounced barrel shank or relatively heavy barrel, they will use MEDIUM rings.
