I tried and immediately removed the Springfield (Inc.) "Scout Squad" rifle mount with the M68 CCO (Aimpoint). It works, but obscured the iron sights and has a slightly different zero than the irons. The mount gets quite hot if you shoot a lot, but I don't know if this affects zero or not. This was a standard issue M68 CCO, so different mounts may not block the iron sights. The Springfield Scout Squad mount itself is merely held on by a couple of set screws and I'm not confortable it'll withstand even slight abuse without moving out of zero.
I use the M68 on my M4 Carbine, but am quite happy with the iron sights on the M14.
