You do loose accuracy with a chome-lined barrel. It should be bight like chome.

So what are the pros and cons of having a chrome lined barrel??

The accuracy impact is very small.

Take apart your upper and use a light to light up the chamber, you should be able to see a light "gray-white" ring around it. That is the chrome.

You can do the same thing at the barrel end. If your FH is off, look at the end of the barrel. You will see a small white ring in the cross-section of the barrel. That is the chrome.

Besides loss of accuracy of course.

Most barrels will be marked on barrel by the front sight. On my bull barrel, its marked under the handguard. Chrome lined barrel will last much longer and is easier to clean plus chrome lined chamber will make feeding and extraction easier. Over all, accuacry difference won't be noticed unless you are one hell of a good shot.

Is crome lining really necessary in this day and age with non-corosive ammo when you own a semi-auto weapon?

I bet the accuracy loss is almost unnoticable and 99% of shooters on this board wouldn't even be able to tell the difference.

I guess the question is, why not? Ease of cleaning and corrosion resistance isn't a bad thing so I'll take it any day over non-lined...

I have a non chrome lined J&T 20" upper, and I can't tell the difference in accuracy between it and my shorter chrome lined ARs. I do know that the J&T takes about 4 times as many patches before it starts to get clean, whereas my chrome lined barrels only seem to take a few. YMMV
