AR 15 Barrels and recievers
I have always been under the impression that if you wanted your barrel to last long at all you should get a chrome lined barrel and chamber or a chrome molly barrel. Yesterday I was told that you don't need any of those things unless you live around or have your firearm around saltwater. Is there any truth to this? I am wondering because I am planning on buying a new upper for my Olympic Arms AR rifle and don't want a barrel that will only last a few hundred rounds. I thought that the reason the M-16 had so many problems at the onset of Vietnam was because the barrels were not chromed and the chambers were not chromed lined. Of course I know that the forward assist helped too. Any information that you all could give me would be great. Thanks:D

The chrome lined barrels were designed for heavy rate, sustained, autofire.

In a standard AR, you don't need a chrome lined barrel, though they will last a little longer, they are just not as accurate.

For a minute of bad guy weapon, chrome lined barrels are fine.

For a varmint shooter at 500 or 600 yards, then you want more of a dedicated accuracy barrel.

Chrome lined barrels are more forgiving and easier to clean, but the 5.56/.223 round is particularly fast, nor is it a high pressure, "barrel eating" type of round.

With good cleaning and moderate understanding of firearm's maintenence, a normal barrel will last you much longer than you will probably use the weapon, to be perfect honest, in most shooting situations.

Now, if you are part of a tac-team, with entry drills, live fire scenarios, thousands of rounds a month leaving the weapon, yes, you would prefer a chrome lined barrel.

Thanks for the advice. I am going to go to Knob Creek's Machine Gun Shoot this weekend and am going to try and find me a decent upper for plinking and maybe some varment and deer hunting as well.

Thanks again.
