Yes, that's true UT, but remember the insides of the rings are concave. The outside of the inserts are convex. THis may sound like an over-simplification, but there's a madness to the method here. When tightening down the rings,
theoretically the inserts should slide into position within the confines of the concavity of the rings. But, if they don;t, it means there's a little space there that they'll eventually want to get to. Recoil may eventually fix that problem for you........ and leave you with loose rings and an ineffective scope.
Now, if you loosened the rings and pushed the (front) insert back a little, so it was centered in the rings, then when you tightened it wanted naturally to squeeze back forward again, that would be different. That would mean the insert truly was aligning itself with the concave inner side of the ring. That would be good(!). But if it squeezed forward just that first time when you tried to install it, but then didn;t squeeze forward after you fixed it, that would mean something else. I think anyway........
What I did when installing mine was to take an upper ring half and push the insert into it. It slide around pretty easily, which is why the halves won;t always stay even with the ring halves. But if I pushed the insert into the ring half with my thumb, using a noticeable amount of pressure, the ring was centered in the ring half. Why? Because the apexes of both the ring and insert aligned themselves. The insert did not protrude forward or rearward of the ring.
I hope that explanation makes sense. I'm beginnign to wonder if it even makes sense to me!
