Stock inlet question

[Petersen]

Stock screw spaced Remington long action. Bottom is milled out a little different. No stock material in front of trigger area and rear of mag box area a little wider and that area goes most of the way up. BDL floorplate will fit with small gaps on sides. Kwik Klip is too tight but could be opened up for it. It was definitely cut for something specific, trying to figure
Out. Any ideas appreciated. Thanks
