I have sets of M40 A3 type rings I sent off for coating. After sending them off I remembered my marks on which way the ring caps face will be removed. Are they indexed front and back? I don't mean between the rings as the front is 6 screw and the back 4 but does it matter which way the cap faces on the individual ring? Never realy thought about it before but have always tried to keep them the way they came out of the package. Neither set is lapped. Any help appreciated.
