| Can a cam pin being too tight or too loose cause any extra wear, reliability, or accuracy issues? Or is a cam pin just a cam pin? If you were able to choose, would you pick one that is a little tight going in and out of the bolt or one that goes in and out with ease? Thanks in advance for the info. |

Gee... my thoughts are that they should "fit". The pin should be able to slide in and not be overly tight (they only go in one way).
But if it is so "undersize" so it is sloppy; the slack (now I am guessing) could cause extra wear by allowing sloppy parts to slam together; not operate smoothly. Usually if the bolt flops in and out (too) easily the gas rings are worn (on the bolt). |

Accuracy? I bet you could argue that the cam pin has to do with bolt positioning and repeat location, and thus consistency/accuracy. But id bet carrier bore and bolt fit would effect that even more. If the tolerance stacking worked out right it could have an effect. I would have to believe it would be such a small difference to be a non issue.
Wear or reliability? No way. You have to figure with as many rifles as the DoD fields and as many rifles there are in our hands a cam pin tolerance issue would be known-addressed-and fixed by now. I don't mean to sound like a dick but none of us weekend warriors will ever discover a problem inherent in these systems. They are too widely fielded and worked on by armies of engineers to have issues. Sleep tight in knowing you have one of the the best weapon systems In the world. |
