scope ring mounts best for vulcan

o got my swfa 16x coming in the mail now what brand of rings fit the vulcan best and i don’t want to spend 100.00 more like 30-50.00 i tried some b-square and they fit ok but didn’t look like they had much grip on one side, good on the other …and the bolt is small looks like theres room to move some ….. it looks like weaver rings have a square bolt that would fit the gap in the mount much better less room to move.and had a bigger bolt to tighten it all down are they good …… without spending as much as the scope … have u guys found a ring that fits the vulcan rail better ….
