Flatline Ops - Leupold Mark 4 30mm Ring Top Folding Level


A Flatline Ops folding bubble level built in to a replacement ring top for your Leupold Mark 4 30mm Rings!

Flatline Ops custom fitting level for MARK4® Leupold® 30mm scope mounts*. Our MARK4® Adapter replaces the top of your existing Leupold scope ring for a custom seamless one-of-a-kind fit. 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 a dual-position detent locator to make sure you are locked into place before taking that critical shot.

Solid, Durable Construction

Each level is machined from advanced 6061-T6 aircraft aluminum and then black hard anodized to protect it from the extremes of the outdoors. The level is also designed to fit right- or left-handed shooters.

High Visibility

High-visibility fluorescent fluid level is easy to visualize and locate before each shot. You also have the ability to make fine adjustments to the level in the open and closed positions.

  • Each ACCU/LEVEL™ comes complete with a Dovetail Accessory Lug for fast and easy addition of the Flatline Ops STRONG ARM™. If you have different size levels on multiple firearms, the STRONG ARM™ and ADI accessories are interchangeable with every ACCU/LEVEL™ size.
  • Quick and easy installation
  • Install without removing scope (in most cases)
  • Ships with instructions and all installation tools

* MARK4® level does not come with base rail mount. Level mounts directly to your existing MARK4® Leupold® 30MM scope mount.
