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.
These posts are not compatible with standard A2-style sights.
