Dimitri with Primary Arms does a great job in this video of explaining CoWitness both absolute and lower 1/3. One of the reviews we are working on and should have up in the next week is the Texas Weapons Systems (TWS) Kalashnikov Handguard. Right out front, one of our major issues with this handguard is the lack of CoWitness. This is a great video that explains what we will be discussing when we talk about lower 1/3 CoWitness.
