Clever Bubble Levels from Flatline Ops

    To my knowledge, this is the first time TFB writes about Flatline Ops. They are based in between Seattle and Vancouver, British Columbia, in the city of Bellingham, Washington, where they design, engineer and manufacture their products.

    Their product line consists of shooting bags and accessories as well as a wide assortment of scope levels. Flatline Ops’ latest development is a scope level that can be mounted to most if not all Spuhr scope mounts. In case you do not own such a mount, they also have levels for other brands as well as Picatinny mounted solutions.

    TANGO SM SPUHR Mounted articulating, fine-adjustable level:

    The TANGO SM ACCU/LEVEL™ is Flatline Ops’ newest SPUHR® mounted scope level. It boasts the industries only SPUHR® adaptable level that is ‘micro fine-adjustable’ after installation. The Tango SM™ features interface locating rings that nest into the SPUHR® interface to assure a precision fitment.

    Machined from 6061-T6 areospace grade aluminum and Mil Spec type III hard anodized for harsh conditions and abuse. The Tango SM™ boasts its patented articulating level arm, when not in use, the arm can be tucked into the body for safe travel and protection. When you are ready to use it, simply articulate the level arm out and you are ready to go.

    A long-range shot has many factors to take into consideration to be sure you are on target, and our ACCU/LEVEL™ system aids in the correction of “cant error,” giving you dead-on true vertical hold. The level also features an ultra-low profile and machine precision design to make sure you are locked into place before taking that critical shot.

    Here you can see the bubble from “your” position in the “on” and “off” positions.

    My suggestion is that you do not buy a bubble level that doesn’t have the micro-tuning like this solution from Flatline Ops. I did, and it was off by quite a bit.

    The price is $129.99.
