Re: EGW mount shows gap after installation
Very good advice by 'Broz' and 'bigngreen'.
I would add: While the bedding epoxy is wet and not set up, the idea is to lightly torque the base screws down until the base just makes contact with the top of the receiver, so that when the bedding glue sets up, it fills any voids from uneven contact. You don't want to overly tighten down on these base screws, deform the rail to fit any unevenness on the top of the receiver, and squeeze out all of the epoxy bedding compound.
Then - only after the JB weld sets up 24-48 hours - torque down the 4 base screws to final torque.
PS: Place a straight edge along each side of the one-piece rail and make sure it's running parallel to your barrel - not pointing leftward or rightward along the length of the barrel - before letting the bedding epoxy set up. That way your rifle won't shoot curve balls/bullets... seriously...
I use EGW one-piece rails on my Tikka T-3 Lites, but those receiver tops are perfectly flat the full length of the receiver, and the flats of the EGW bases fit on these flat top receivers like a glove. Never used an EGW on a round or oval topped receiver, but if the top of the rail is reasonably flat after your epoxy bedding sets up, I'd mount the scope and go for it.
