Installing a free-floating front rail on an AR is a common upgrade, especially for this who want to hang extra optics, flashlights, or other doo-dads on their guns. But you need to make sure that the rails are perfectly aligned, especially if you are mounting optics.
In this product review Jack Landis looks at one tool from Brownells that can help make this job much easier. Handy to have for your own guns, and certainly a good tool to have for the professional gunsmith.
