couesaddict, you are correct about the feed lips, if using a detachable magazine but, a Remington 700 BDL and ADL use an internal magazine box with no feed lips. Instead, it uses the underside of the action, the bottom of the bolt slide rail, as feed lips. When going to a detachable box magazine from a Remington 700 ADL or BDL action, you usually have to modify those bottom rails to make the magazine feed properly.
The replacement Wyatt's internal magazine box works just like the original Remington box, except with a little more room lengthwise. There are usually no feed lips on the Wyatt's internal box magazine either. That would suggest to me that the gunsmith altered the action bottom, widening the bottom of the bolt slide, but for what reason I have no idea...
