Have seen a few XBolts now and have seen the rings mounted 2 ways. 1 the way stated with the L part both facing in and the other with both L's facing to the rear.
Mine is the later(know of 3 this way) and seems to center the rear ring better on the tube. Not sure it would fit turned around. Im just looking at a pic I have though. Ill have to look better when I get home.
It was done by a reputable gun shop but was one of the first X Bolts in Alberta so maybe it was done wrong. Sits level and shoots good but will have to have a look.
