Us optics rail mounted fixed bubble level, bbl-100 - U.S. Optics Rail Mounted Fixed Bubble Level

The US Optics Rail Mounted Fixed Bubble Level, BBL-100, is a well machined and quality built anti-cant level at a reasonable price. Light weight and relatively compact, this level only slightly protrudes a little more than my angle degree indicator. If you do not have an angle degree indicator and do not want this protruding off the side of the gun permanently, step up another $20 and buy the BBL-300 swivel level. The BBL 300 will swing out of the way when not in use. Easy to transverse from dominant eye back to non dominant eye to check for level with the advantage of not needing to look over scope at a ring mounted bubble. This translates into faster shot acquisition and better shooter accuracy/consistency as the shooter does not need to constantly reposition the shooting eye behind the scope. I would like to see a lanyard attached to the aluminum level cover as this is a small piece and can be easily lost.
Pros: Quality construction, sturdy, US Optics excellence, ambidextrous, reasonably priced
Cons: Needs a lanyard for the protective cap.
