DuraSight Sighting Systems was created in 2005 after a group of gunsmiths got frustrated in dealing with the sheer number of accuracy complaints related to what seemed to be quality rifles.
When these gunsmiths would inspect (and shoot) the rifles in question, they almost always determined that it was not the rifle or the scope that was causing accuracy problems but rather the cheap aluminum mounts being used. Once the gunsmiths replaced the aluminum mounts with a stronger scope mount system, the accuracy issue went away.
These gunsmiths also realized that not every shooter could afford to spend $80 to $100 on scope mounts alone. So the group of gun builders set out to find a material that performs like steel but can be manufactured at a more affordable cost. Enter Z2 Alloy.
