The Monstrum Rifle Scope Level Bubble is a tool built to check for proper vertical alignment of your rifle
Imperfect vertical alignment of your scope when shooting introduces scope cant error - horizontal drift of your shots due to cant - An anti-cant level bubble corrects for this issue, allowing you to quickly check for proper alignment of your rifle before each shot.
The level bubble attaches to your rifle scope via the integrated ring mount - for 30 mm diameter tube rifle scopes
The innovative design folds out when needed and tucks away neatly when not in use
