FLATLINE OPS, INC. - Tango RM Accu/Level

Easy install and use.

Extremely high quality, well-made item. Tight hinge with no vertical movement. Thank you Brownells for sending the upgraded Tango RM 2.0 (7075-T6 Aluminum) version rather than a left over stock Tango RM (6061 -T6 Aluminum) as shown on your website. Nothing but good experiences when purchasing from you.

Love this whole concept. Quality construction. Being able to fine tune any level is awesome

I wanted an easily transferable anti-cant device that could go from one gun to another without the necessity of removing it from the scope body, and then remounting/leveling on another scope. Ive found mounting/leveling anti-cant devices on the scope tube to be tedious. This product caught my attention with its ability to fine tune the accuracy of the level. Ive avoided other rail mounted levels as Ive seen several products that werent level from the factory with no accommodation for adjusting them. I mounted the Tango RM Accu/Level on a Badger Ordnance Dead Level (093-000-051WB) to fine tune it prior to installation, secured the set screw with a dab of purple loctite, and mounted it to a 6.5 CM AR-10. This combination has held level for a couple hundred rounds. Long term durability is still unknown, but the adjustment and installation were simple. My only concern is the durability of the two rather slim screws that secure the mounting hardware to the picatinny rail. I like being able to fold it out of the way when not in use to reduce the chance of damage. In a perfect world, I wish it had some ability to put a small LED light or chemlight on the device for use in limited visibility, but perhaps someone can 3D print something to accept a small chemlight while blocking the illumination from the front.
