Buying SCHIT glass,is false "economy" and same goes SCHIT mounting systems. Start with SCHIT and you will fhuqking always end with SCHIT. Hint.
Were your VERY Tender Feelers not involved,you could have basked in the long term sanctity of wares,that actually fhuqking work...start to finish and been into same for under 350 Clams turn-key,with glass,mount,rings and caps. Then you could have learned that which dictates POA/POI intersections,as per fhuqking whim. Hint.
Just sayin'.............
