Replacement aperture for all C4 Front Sights, available in many sizes for your specific application.
Features and Specifications:
Manufacturer Number: UD10640
Aperture Type: 14 MOA
Elevation: 1.25 MOA per 1/4 turn
MOA measurements are for applications that install the front sight at 27 inches from the user's eye. This is equivalent to the C4 Dynamount sight mounted on the end of a 16-inch barrel. Shorter mounting distances will increase the effective MOA, longer mounting distances will decrease it.
For precision shooting, USA Shooting recommends a front aperture size that provides at 3 MOA or more all around the target. For precision shooting with 4 MOA targets, our 10 MOA aperture is a great fit. Those with less precise but greater speed requirements will find larger sizes to be a great fit.
The size included with all C4 Front sights is 12 MOA.
