Good point. I looked at the Qloader website, and while they have a bunch more options than I knew about, none of them seems quite right (if I ever decide I like my Qloader enough to put it on my vike, i'll use one of those adapters).
I'd prefer at this point to stick with the 90* warp adapter from AGD, since it also fits perfectly on my Automag. And the powerfeed plug can be rotated to stop balls from entering the breech.
When I end up with a solution I'll post it up with pictures.
