مستوى فقاعات 34 ملم من فورتكس أوبتكس للنطاق

I was skeptical about needing a bubble level at first, but this one fits snugly on my 34mm tube and the bubble is easy to see while shooting prone. It helped me get consistent vertical alignment for three consecutive shots at 600 yards.

The mount was rock solid on my 34mm tube, and the bubble moves smoothly with no hesitation. It slid right into place and feels much more secure than cheaper plastic levels I've tried.

I was worried about canting throwing off my shots, but this bubble level made zeroing in perfectly vertical super easy. It clamps onto my 34mm tube without shifting, and the level itself is clear and responsive.
