Most Helpful Positive Review US Optics Rail mounted bubble level
The device is well made, and works just as you would expect. The swivel is worth the extra money because otherwise, unless the level is removed after shooting, it is only a matter of time until the fixed level is accidentally broken off. It is worth noting that the rail mounted level actually indi...

Most Helpful Negative Review Not Grunt Proof
This thing didn’t even survive the mounting process. I put it on my rifle, tried to swivel it closed, pin fell out, whole thing came apart. Worst piece of junk I have ever purchased! Needs major engineering work to fix: make with a pin retainer, use better detects, add a lock/unlock function th...

Super simple / easy install

by Steve, Verified Owner from NJ, United States Written on February 2, 2025
This level fit perfectly under my scope, just in front of my parallax adjustment. Folds easily out of the way. The liquid is bright green, bubble is about half the size of a bubble on a construction level. Easily seen without breaking your cheek weld vs levels atop scope rings.
Pros:
  • EASY INSTALL
  • Protective cover included
Cons:
  • bubble a little small
Best Used for:
  • long range
Would recommend: Yes

Quality Upgrade

by Mike Diggs, Verified Owner from AE, United States Written on February 28, 2024
Hasn't failed me yet; easy to install and operate. Nice of them to add threading on the other side to hold the cap so it's not misplaced.

Light weight but cheaply made

by Gunflash, Verified Owner from AR, United States Written on November 23, 2022
Looks good and is very lightweight aluminum as is the screw that tightens it to be able to secure it to the picatinny rail. I mounted it and tightened it down and the aluminum screw broke. Why would a company use an aluminum screw? For almost $95 they should give it a metal screw and a inch lbs to be tightened. Just a FYI.
Pros:
  • Lightweight
Cons:
  • Aluminum screw is cheap.
Best Used for:
  • Anti-cant
Would recommend: No

Disappointed so i returned

by Dave K, Verified Owner from AZ, United States Written on November 7, 2020
I received the level and mounted to my egw rail and it is not level. I could also touch it with my finger and it would change. It looked as though the pin in the bottom was too deep and maybe not catching enough material. Not sure if this is normal for these but definitely not what i needed.
Pros:
  • Looks nice
Cons:
  • Didnt function correctly
Would recommend: No

Do not buy ���

by joe, Verified Owner from CA, United States Written on September 12, 2020
I purchased this product expecting it to be a quality product with how much it costs. The level will not level on any surface(tested against 2 levels). I would not recommend this product. The machine quality is okay but feels really flimsy.
Pros:
  • None
Cons:
  • exspenive
  • dose not level
Would recommend: No

Very Nice, Very Expensive

by CC, Verified Owner from CA, United States Written on September 8, 2020
All around really nice folding bubble level, but crazy expensive for what it is. The cap is very easy to lose too. Easily installed. Easy to see on gun. If you use levels a lot and have the cash to blow, this is one of the best.
Pros:
  • Easy to see
  • constructioin quality
  • Cool Looking
  • Ease Of Use
Cons:
  • Expensive
Would recommend: Yes

No longer level

by Anthony, from IN, United States Written on July 27, 2020
I guess I'm the only that's run into this problem but it's no longer holding true. I thought something was off and compared it to carpenter levels I had at home with a noticeable difference. I've had it mounted to my Ruger for the past year and change, hauling it back forth to the range but no more excess wear than one would expect
