I searched for a thread with pictures of various bolts, and was unable to find anything.

Who makes the "MP" marked bolts where the vertical line in the P is the right-hand vertical line in the M?

BCM sells them - but, do others make them. I ask because I bought a Colt bolt that has this marking style, and so I suspect it is not Colt. Thanks.  By the way, there are no other markings on the Bolt. I haven't removed the extractor yet to peek under there - but I intend to later.

Any advice would be helpful.
