I picked up a new LE6920 last month. Was cleaning the cosmoline out of it when I noticed the Bolt only had "C" rollmarked on it, not CMP. Worried, I called Colt cusomer service, where the nice lady informed me that Colt has not put CMP on their bolts for quite a while, and that I could rest assured it was fully tested and proofed. I suppose my fears of having a non-proofed bolt are put to rest.
But what does everyone else have in their LE carbines? Are your recent bolts marked C or CMP?
BTW it has the M16 carrier with no other markings than a rollmarked dot on the top of it. What does everyone elses carrier have?
If I seem to be a Colt newb, it's because this is my first Colt rifle since I was issued a new Colt M16A2 in 1983.
