Hi all I just recently picked up a clean m77 mkii boat paddle in 243. I guess I assumed all the mkii rifles were crf but this one has a lip at the bottom of the bolt and is push feed. It has a blade style ejector. From what I understand only the very early mkii were push feed? Is that lower lip something a machinist could mill off or is it something I should leave as is for reliability/ safety reasons or collectibility?
