Help with the colt LE6920

This friday i plan on purchasing a colt le6920. I just read on another forum that the 6920 is not made with the chrome lined barrel anymore. And that the pin for taking it down is not size as all the other ars. And something about a blocked sear pin making it uneasy to replace the trigger? I apologize for not knowing what exactly im asking about as i am new to the ar platform. But i need to learn about this before i purchase this rifle. Please help me to make the right decision. Thanks!

Use the search button at top and look at all the 6920 threads. Whatever you read on that other site is from some 15 year old who is in the basement of his grandmas’ house.

Ok. Thanks.
