The sight plane for the Centurion Arms C4 sights sits 2–3 mm below standard AR-15 sights. This poses no problem with Aimpoint's 30 mm optics, but the sights aren't visible with a T1 on a LaRue LT660 mount. Does anyone have a recommendation on a good T1 mount to run with the C4 sights? I tried a LT660HK mount, but it gives an absolute co-witness, which I don't care for.

Thanks,

Andreas
