weaver / picatinny question

Is there such thing as true picatinny rings??

I have bought a Warne picatinny rail. Picatinny rails seem to be available in abundance from most base manufacturers. However most rings are listed as "weaver type".

Now I learned the difference between the 2x systems on here before and I have discovered that my burris signature rings which are listed as weaver; do fit my rail.... However there is a little front to back movement.

I've been advised to push the rings to the front of their slot before torquing accordingly, but I'm wondering if any of the manufacturers make a "true" picatinny ring with which I'll have no front to back movement? ? Is this even an issue? Is a little movement to be expected?

Please settle my curiosity?

Once they are torqued down there should be no movement at all. They are pretty much the same.

Makes no difference.

The reason for pushing them forward is the backward movement of the rifle under recoil. If the rings are pushed forward then they cannot"slip" forward any further. As said above if they are pushed forward and torqued down there won't be a bother.

Thanks for the replies. Just purely curious though if rings are available with lugs / pins that fully occupy all of the space inside the picatinny groove? I'm guessing though that the tolerances would have to be minute to make such a ring worthwhile.

There probably is, but i'd say most manufacturers just make them Weaver as it suits both types of rails. The cost of making, marketing and selling picatinny specific might be more than it's worth.

As for the actual difference i believe it's in the region of 0.6mm per recoil groove. That is the width of the groove only and not the spacing between them.
