Question for AR Experts

[Redneck1919]

Can anyone tell me the difference between a Colt LE 6920 and Colt LE 6940 models beside the obvious numbers and why the LE 6940 lists for more?
Thanks,
Jim

for the most part the two are mechanically the same. The difference is the 6940 has a true one piece full floating quad rail and is comes with the Socom style sights. Those are really the only two differences between the two.
