Flatline Ops TANGO RM 2.0 Ultra Precision Articulating Pic Rail Mounted Bubble Level

Description

Cant error is a small mistake that turns into big misses as distance grows. When the rifle is rolled even slightly, your elevation and wind holds stop tracking in a clean vertical/horizontal plane, and the shot drifts off-axis. The Flatline Ops TANGO RM 2.0 Ultra Precision Articulating Fine Adjustable Pic Rail Mounted Level is designed to give you a true vertical reference that’s easier to see, easier to place, and easier to dial in correctly.

This version mounts to the picatinny rail and uses a horizontal articulating arm to position the vial where it’s most readable from your shooting position—especially useful behind taller optic setups, clipped-on accessories, or when you’re driving the gun hard in awkward terrain. Visibility is a big part of speed and confidence, so Flatline Ops added the FlashBore hollow vial tip, which improves illumination through the vial for quicker bubble acquisition in low light or heavy shadow.

The body is machined from 7075-T6 aerospace-grade aluminum for high strength and rigidity, then protected with a Type III hard anodized, mil-spec finish to withstand abrasion, weather, and hard use. The level uses a high-visibility fluorescent fluid for rapid reads, and the design is ambidextrous, supporting both right- and left-handed shooters.

Most importantly, the TANGO RM 2.0 includes patented fine-adjustment capability post-install, letting you true the bubble precisely once it’s mounted—because alignment is everything. Installation is intended to be quick and practical, and in many setups you can install it without removing your scope.
