..on the rear, exterior surface of the receiver.
If you have the recent Czechpoint Sporter with the fixed, black plastic buttstock, you know about the >> Very narrow, rectangular openings << in the receiver.
* My receiver's rear surface has no round openings (

-except for the stock screw's hole-), certainly nothing which remotely corresponds to the round shapes of the three 'dimples', all of which seem to protrude from the ferrule.
----If receivers on the original military VZ-58s had No corresponding recessed areas, why did ferrules have three dimples?
Nobody else ever seems to discuss this basic, specific subject for mating the beaver stock to a modern Sporter. Naturally my beaver barf furniture arrived with No metal accessories.
