The Schmidt & Bender MILITARY MK II 5-25×56 mm scope used by Harrison on the L115A3 Long Range Rifle has windage and elevation adjustment of 0.1 milliradian (mil), double turn elevation turret, and parallax and illumination control. The sight has a maximal vertical elevation range of 26 mil, and the sight adjustment increment of 0.1 mil equates to a point of impact shift at a distance of . To increase the maximal elevation range Accuracy International produces mounts for telescopic sights with a 13.1 mil (45 MOA) built in vertical cant designed for their .338 Lapua Magnum rifles fitted with the 5-25×56 telescopic sight. Even with a 13.1 mil canted mount the employed sighting system is not able to dial in over 39.1 milliradian of vertical aiming correction, which is significantly less than Harrison required during his record shot.
