Follow some expert gunsmiths at Brownells as they walk you through simple procedures for customizing, repairing, and maintaining your firearms. This weapons video tutorial will teach you how to measure rear sight heights on your rifle.

Brownells shows you the step-by-step process to correctly measuring back sights for your rifle using your work bench. This is handy for rear sight height calculations for a gun that's never had sights put on before. You only have one continuing line on any firearm, like a pistol, handgun, rifle or shotgun, and that's the bore line. Just take a measurement at the front sights and do some simple math.
