| I've owned 3 Colt bolts and I have noticed that all of them have little dents behind each bolt lug. What are these marks? Also, I noticed that my third bolt only has these marks behind half of the lugs. What does that mean? |
Thanks for the info. Why would they only stress relieve 4 of the 7 lugs, though? |
| I'm looking at one of my Colt bolts and it has the straight line relief mark behind every lug. Yet another seems to only have four. Both of these are marked MPC. I have a later M4 Colt bolt (MPCK) that doesn't have ANY of the relief marks. I also have bolts (can't remember if they are Colt or not, but chances are Colt) that have a half moon type relief cut instead of a line mark. Interesting. |
