Anyone have a Leupold Alum 20MOA pic rail on an Xbolt?

[HockeyDad]

I just mounted an aluminum Leupold 20MOA picatinny rail on an X-bolt. Notice the screws in the back go all the way into the body of the rail, but the screws up front don't.

Is this normal / correct?

I tightened all of them to the 22 inch pounds Leupold said to.

The screw holes up front are shallower, most all manufacturer's use the two different sized screws with the X-Bolt. Make sure you have the correct length bolts in the correct location.

10in lbs up front & 20in lbs out back is what Murphy Precision recommends, so that is what I used with blue Loctite

I am curious about one thing, did you put a bubble level on the rail after you installed it? Was the front and back in the same plane or was there a slight difference between the two?

It took 2 tries to get the rail on the newest X-Bolt flat and square front to back. I thought I was going to have to bed it. I apparently was inducing a twist into the rail with the method I employed tightening it down. Baby steps fixed it.
