Tactical Outdoor Mini 2Pcs Magnetic Bubble Level Mounting Leveling Tool with Magnetic Base and Adaptable Gunsmithing Maintenance Rifle Scope Misaligned crosshairs rob you of accurate bullet placement, especially at long range, where it counts. Crooked crosshairs cause your scope adjustments to be unreliable and even make zeroing your firearm a frustrating and costly experience. The Level-Level-Level works because the scope is leveled to your receiver, not to the top of a scope base. ACCURACY: Ensure crosshairs are aligned for in line shot placement and reliable doping adjustments EASE OF USE: Place the Scope Turret Level on the top scope cap and the Action Level above the bolt; once the levels show a level scope, simply tighten the rings down VERSATILITY: Works with practically any bolt action rifle and can be adapted to work with other rifle designs COMPACT: Small size allows for convenient storage and transport INCLUDES: A magnetized Action Level and a non-magnetized Scope Turret Level
