DISCOVERYOPT Multi-Compatible Scope Bubble Level | Fits 25.4mm/30mm/34mm Tubes | Precision Alignment Tool

Solid construction and easy to mount. Works well when positioned so you can monitor it with your non-dominant eye while aiming. That said, the fluid is quite thick, which makes the bubble slower to react. After each shot, the bubble tends to split into two and takes some time to settle back, which can be a bit distracting.

Livella x ottica

La livella non è indispensabile ma è un buon accessorio per livellare l'ottica e anche l'arma stessa
