Who owns a CZ MTR,or an RAP?

I think, in my simple-engineering style mind, that the RAP problem has to do with switching it from a centerfeed (as the original mags) to a right-left feed (as an AR mag). The feed ramp in the front of the rcvr has been left as a single ramped slope/gap (which also works for the AI style 243, 6Creed/308 etc), whereas if you consider the AR, there is a double feed ramp, as in the "M4" style. It extends into the receiver metal but just the fact that each round has a guide more lined up than it would in a single-ramp setup... anyway that's what came to me last night as I was looking at the action and feed path. the tip -- about 90% of the time -- hits the back of the barrel, the vertical flat "wall" about 0.2" or so below the chamber entry. there are 2 spots of brass marks (90 gr Fed factory AE's) one lower left and one lower right, from the chamber entry.
I don't necessarily need it to feed suuppper-slow on the bolt..... but at a normal bolt cycle rhythm, we should be talking near 100% feeding... just like any other rifle would.
