 | | The XM107 rifle, meanwhile, has a pop-up iron sight that, when raised, is directly in front of the objective lens. |
 | | As noted by the agency, however, front and rear pop-up/fold-down iron sights are a permanent part of the XM107 rifle, as specified in the official configuration for that weapon. |
 | | Further, the agency tested the sights with the iron sight folded down, since it is positioned directly in front of the night sight’s objective lens, and thus would obscure part of the lens if left in the raised position, thereby reducing the amount of incoming light and the resulting image quality. |
