Serious long range shooters will be the first to tell you that the set up for the shot is the most important part of making the hit. One of the oft overlooked issues setting up for that long shot is rifle cant. Without the rifle being perfectly level, no amount of dialing of turrets or holding off in the reticle will help you. College Station, TX based iota was showing off their illuminated, bubble leveled, semi custom fit rings at the 2017 Media Day for SHOT Show. 
According to their CEO, what sets the Triad ZL apart from the competition is the included Picatinny Key System that allows you to press fit your rings to your Picatinny base of choice, eliminating forward and backward movement. On its own, this is a very solid mount, and one I would be excited about. 
More interesting than their unobtrusive bubble level is the integrated low power LED that casts a glow on the level as well as the elevation and windage turret, allowing you to see your scope setting in near/total darkness. Given the amount night vision pig hunting opportunities available in our part of Texas, this seems to be a solution for a problem, namely confirming your zero and elevation settings in the dark.
For those who are already happy with their scope rings, iota sells the bubble level and illumination piece as a standalone item called the ZeroLight. Similarly, you can buy just the mount system with accessory keys. MSRP on the Triad ZL is $199, right in line with what a high quality set of rings will set you back. Check here in the next few months for a review as we’ll have a set for testing shortly.
