I also bed the scope mounts to the receiver using JB Weld. I use Teflon spray on the receiver, bolts and bolt holes, clean the bases then apply epoxy screwing them down into a neutral position (not torqueing them). When epoxy set I then take out the screws and use blue lock tite and torque.
For me the point is to epoxy it all into a monolithic mount, screws, bases, receiver... all of it.
