EZshootScope Leveling Kit, Scope Level for Single Picatinny Rail and Universal Magnetic Scope Level Tool,High Precision Scope Bubble Level

This scope leveling kit is great, especially for the price. I like that it is magnetic and that it is extremely accurate. It will work on multiple firearms and would be a great gift for a firearms enthusiast.

Although I have not actually used these yet to help sight in a scope at the range I did attach them to check them out for ease of use and quality. And I have to say they are very easy to attach and use. However the view status is not as precise as promoted. These are nicely made levels, but to me the bubble indicators should have been made a little more tightly aligned. I have some other use type levels that are exceptional and these are just average. However, they will do the job of assisting you in getting your scope matters under control when trying to zero things in best you can. The one magnetic level of two levels received arrived with the bubble glass itself dislodged from the metal holder probably from rough shipping conditions. But nevertheless it should have been better secured on the manufacturing end. Especially at the price point these are going for. For those 2 issues I have to remove a star.

This items quality is quite poor but I guess you get what you pay for

great design in theory but fatal manufacturing flaws rendering product uselessI am disappointed in the poor manufacturing flaw that made this product useless. The website headline falsely claimed quoting verbatim, “High Precision Bubble Level”. Please look at the attached photographs. Both of the levels are useless because the bubble is too small. A truly “High Precision Bubble Level” has a bubble that just barely touches the level lines on both sides so that you can accurately see when you have a level surface. The bubbles, in both of these levels, are so small that you have to guess the middle position of the bubble which IS NOT precision. You can accurately align a level only when the bubble is the correct size. Apparently the manufacturer has no Quality Control inspections and no shame. The person who assembled these levels should have rejected the bubble vials. The Quality Control inspector should have rejected the finished product.I have a buddy that helped me set up my rifle scope and he introduced me to this system. I was so impressed that I bought my own only to receive a useless product.

Two levels are in the set. The spirit level intended to level the 1913 Picatinny base worked well enough to do the job. Despite the description of the product as "High Precision", it is a standard spirit level, not one you might use to level a machine bed. But for this purpose, I'm calling it adequate.In the package I received, the level intended to sit atop the scope cap is another matter.The bubble changed position almost every time I placed it on a surface. If it indicated level, all I had to do was rotate it 180 degrees to swap ends and it would be a full bubble off. Fiddling with it often brought the bubble back to center-ish, but how could I trust that? A spirit level needs to work identically each and every time.On a positive note, an Allen wrench is included to adjust the scope cap spirit level to plumb. But if the bubble returns to a different position each time, or 'sticks' to one end, adjusting the plumb is impossible.A little about me. I owned and operated a pawn shop and gun store for 17 years. I've put a lot of scopes on rifles and handguns. Getting it right is a bit of an obsession. Am I judging this device too harshly? I don't think so. Is my sample a fluke? YYMV.To illustrate how the scope cap spirit level was fiddly, I put two dots of white out on one end to help identify orientation.Image 1: Both levels on a 1913 rail. After fiddling with the top level, they seem reasonably in agreement.Image 2: The base spirit level with the rifle showing plumb.Image 3: The base spirit level simply rotated 180 degrees. Nothing changed with the scope or rifle. It shows a full bubble off plumb.Image 4: A projection from the scope objective through the ocular. Projecting onto a plumb bob string hanging on the pantry door, showing the reticle is in perfect orientation to the rifle.

I am impressed. These levels were spot on, right out of the box. And if they get off they are adjustable, so you can true them up easily.A level only has one job. If it is not level it is worthless. It is easy to check a level to see if it is on. Just set it on your bench and then rotate it end for end. Make sure it is in the exact same spot. If it reads the same both ways it is on. If they are not the same, send it back because it is not level. The last couple of levels I received ended up going back. I have no tolerance for levels that aren’t.But I like these. They are right on and adjustable too.

Granted I already had my scope dialed in at 100 yds but this leveling system did show me that my vertical was off ever so slightly, I never would have caught it had the bubble not showed the difference.

With the rifle in tripod I was able to align the scope crosshairs. No issues with the level attaching to the Picatinny rail.Worth having but probably will not see a lot of use after the initial setup.
