I read to make sure the letter "F" is on the front sight when buying a Colt LE6920. The one I bought - a Colt LE6920 MP-R - has the following: <B>1. What does that mean? Is it inferior? Thanks.

Eta, sorry. You're a first time poster. GD is where crap is slung faster then an constipated ape in a zoo. Your best resource for ar15 questions is in the ar15 section. Top left button.

6920s use the correct FSB, don't sweat it. Sometimes the F is stamped and very faint.
