Vortex Bubble Level for 30mm Riflescope Tube

Vortex Bubble Level for 30mm Riflescope Tube SKU: BL30

Rated 5 out of 5 by from Great quality This level is super easy to install and works about as well as a level can. I have used these in the past, and put them on every hunting rifle I use. In Wyoming close shots are rare, so using these to verify rifle angle before taking that shot can mean a hit vs a miss at normal Wyoming distances, and this is the level I choose for the value and quality.

Rated 3 out of 5 by from very bulky if you're trying to keep a low profile to your scope, but is very easy to see when behind the optic you just have to open your other eye
Date published: 2024-05-05
Rated 1 out of 5 by from Poor execution Ring is too large and bulky lends me to believe they used sub par metal for ring and had to make it this bulky monstrosity to actually work. I'm going to try to return it.

Rated 2 out of 5 by from Poor execution The two screw installation makes this item extremely difficult to install and get it level to the scope reticle. The issue is exacerbated when attempting to use it in conjunction with one-piece scope mounts with limited clearance between the rings and the base. If you truly believe you need a level to enhance your long-range shooting performance, I would recommend something which either mounts to a rifle's top rail or is integral to the scope mount instead.

Rated 5 out of 5 by from It's level Fairly easy alignment, just putting pressure on the screws can change where the level sits, so you will need to offset it slightly, but once on, it sticks out perfectly above the turret where you can see it. Works great for hunting or benchrest, it's light so not hurting you on a hunting rig. Anybody can use this, and should for a more ethical shot placement.

Rated 5 out of 5 by from If you’re shooting at anything passed 500 yards or so having a bubble level starts becoming more important. For the price and making you a better as well as more of an accurate shooter I highly recommend having this on your scope so you’re not shooting canted.

Rated 4 out of 5 by from 90% of the way to perfect. No issues with the level from a mounting or durability perspective. If Vortex used more markings with narrower margins and chose a small plastic pendulum, it would would be in the top 1% of levels. Otherwise, this is the best cheap level on the market.

Rated 5 out of 5 by from Great Product I attach these levels to all of my hunting rifles.223,25-06,308,300 win mag and 300 RUM. Very easy fix for missing a long range shot with left/right bullet drift.
