Level does not properly engage picatinny rails - Hawke Sport Optics Bubble Level for Rifle Scopes

The bubble units base is approximately 2-3mm short of allowing good mate-up with units clamping element. Extreme cant of the clamping element is experienced, giving way to improper rail fit and erroneous read-out. I too was misled by those good/expert ratings. You may add Hawke Sport's offering to the long list of those who can't muster, since the passing of BSquare's good product... if you will.
