I got this off of Bushmaster.com

Gov't. M16's can show throat erosion after as little as 2,500 rounds. However, that is with the lighter Gov't. profile barrel and always under full auto conditions. Under semi-auto conditions, those barrels will typically go 5 to 7 thousand rounds before breaking down badly enough to warrant replacement. Many times, a Gov't. barrel with 1 or 2 thousand rounds will be replaced as inaccurate, when what it really needs is to have the copper fouling removed from the bore. This is a tedious job, but the reward is a "like-new" barrel. This refers only to chrome lined barrels like ours or Colt's. Mil spec. SS109 ammo will not measurably increase barrel wear under semi-auto fire and our mil. spec. (chrome lined) barrel will outlast any sporting rifle barrel - period. More barrels are ruined from over cleaning - or careless cleaning - than are ever "shot out". Chrome lined barrels really only need to be detail cleaned when the groups start to suffer. Otherwise, a little powder solvent (or "Break Free" with CLP), and a few passes with a brush, clean the chamber well, dry everything off and apply a very light coat of "Break Free" or "Rem-Oil" and put it away. We have had barrels here go 20,000 rounds and still be within mil. spec. when treated this way.

BULLSHIT!!! I have 1500 rds through by Bushy bbl and it isn't worn a bit. You will get at least 10,000 rounds out of a bbl easily. Probably 20,000 if properly maintained. Hell if that was true I would need to buy a bbl every few months.

*edit* I didnt read the whole thing. I thought is way the old bullcrap about bbls lasting only a few thousand rounds. Yes that is pretty accurate.

Will my LE M4A3 Do this?

What, work fine if you clean it once and a while?

Yup!

When I was in, I never saw them replace a barrel on anyone's M16.

I figure with the one I was issued, I fired over 50k rounds and it still grouped accurately. On top of that, when it was first issued to me, the barrel and compensator were bright silver from the previous users scrubbing the finsih off, so who knows how many rounds it had through it.

How do you know, do you have a throat erosion guage and know how to use it?

Having said that 7K rounds doesn't sound right unless someone is using a round file for a cleaning rod.
