Daniel Defense now makes one for Docter and JPoint mini red dot sights, it's patterned after the KAC mount for the TA01NSN
clickieOtherwise, I know C4Grant has a mount/sight combo, it has ears to protect the relatively fragile, plastic JPoint, I can't find a pic but maybe he can post it.
Being mounted so high, the cheekweld is not ideal, but it is usable, it's a backup sight after all. Below is must my opion: I wouldn't use the high mounted Docter/JPoint as a CQB sight just because it is one in itself, I'd just learn to use the ACOG for both CQB and longer distance shots, and rely on the mini red dot as a backup the way I'd treat the TA01NSN's built-in BUIS.
Back in 2001 a few of us started a project to make our own JPoint mount, at the time everyone was told the KAC mount was a prototype, and maybe it was then. Of the folks involved that are still here I can remember: KevinB (went by Boland back then), and Victor (now of Tactical Night Vision). A member by the name of jg made some prototypes, we all agreed on one of them. Meanwhile, other people were making their own mounts too, some commercially, some started as private projects. Our project had none of the polished looks of the KAC and Daniel Defense, but it did work.
Anyway I do have some experience with it. I don't use my Optima2000 (JPoint) on my TA01NSN anymore, I got a TA31 and TA31F, I prefer to use BAC equipped ACOGs for both CQB distance and longer shots, for which it was designed, without the addition of another optic.
