Bubble level that fits onto a weaver railing - offset to left or right, depending on fixture.
46mm in length, 11mm maximum diameter.
Weighs in at 8 grams.
Comes prepacked with an allen key.
Manufactured entirely out of steel, with the exception of the bubble retainer.
Useful for longer range shooting, to keep your horizontal crosshair plumb and to ensure that your milrad compensation follows perfectly horizontal or vertical. If your scope is level, you'll have one less factor to account for when calculating trajectory
