Magnetic Acrylic Action Scope Level

Crafted from sturdy ABS plastic and featuring a crystal-clear acrylic bubble vial, this scope level tool measures 6 x 4 x 1.7 cm (2.36 x 1.57 x 0.67 in) and weighs only 20 g (0.04 lbs). Its powerful base magnet allows effortless attachment to ferrous firearm parts — particularly useful on rifle actions, scope rings, and Picatinny rails. The spirit level is calibrated to provide reliable horizontal reference points during scope mounting, helping ensure reticles remain level relative to gravity — essential for predictable ballistic performance. It functions effectively in two primary configurations: placed on the scope’s top turret for reticle-level check, or positioned above the bolt on the action for receiver-level baseline verification.
