Not in question:
1. chromed barrels last longer and are probably more reliable especially under full-auto fire.
2. Chromed barrels are not generally considered as accurate as non-chromed bores.
Please help with these questions and correct my understanding (assume were talking about non-full auto here):
1. From my understanding (correct if wrong), AR rifles in the non-chromed configuration, tend to lose there accuracy from throat erosion more than rifeling wear. Does the chrome stop this erosion (or at least lessen it to a great degree)?
2. If the chrome helps protect the throat from this erosion, does anyone just chrome the Chamber and throat area and leave the rifling alone? (or is the throat considered part of the chamber?)
3. As I am sure that sooner or later, even a chromed throat area would wear faster in this area due to the high heat. When it does, does the chrome start chipping/flaking? How exactly does chrome wear off here?
4. How would a chromed chamber only, affect accuracy? Or would it? I understand why the rifling cant have thousandths variations and be accurate, but does thousandth variations in chambers have any real affect once the bullet is on the rifling?
5. Can a chromed barrel be lapped like a conventional barrel to remove the variations of chrome thickness. Obviously I would expect it to be more time consuming as the chrome is harder to wear away, but would it be that significantly more difficult to have the benefits of a chromed barrel while also being accurate?
Thanks!
