98 rings
Dear Shooter:
Yes, I've seen that abortion they call a mount. I'm right with CNTRYBOY1289 on that!
I would recommend the Redfield one piece mount already with the clearance for the clip bridge clearance.
The problem I've run into on Mausers using the Weaver system is the rear clip bridge. I grind (grind and file) it down to the rear radius on that bridge and you can not be sure it is ever in line with the front ring!
The way I do it for Weaver is to do the rear work, get the action level, use my calipers on the front flat with the bottom of the reciever, scribe a hole through the front hole (put it almost flush with the front of the reciever rin so your rear doesn't go into the lug area) ream, drill and tap that hole, attatch the front base, check for level and then coat the rear bridge with dykem, take a level to check the front and transfer to the rear bridge and with a flat file under my level (that has been checked out on the front) draw the file across the rear with the level, level. I then put the base on towards the front of the altered bridge, scribe a hole and see if it is on the center line made with the file. If not I move my punch over to the center line and drill and tap; if the base doesn't then level with the front use a file to dress one side or the other to get it level with the front. (Weaver baes only)
With the Redfield just get it flat with bottom of reciever and drill and tap - any axial mis-alignment can be taken up with the two rear screws.
Hope this helps.
