I've been researching M4 uppers and someone selling an M4 complete on gunsamerica.com claims that his M4 is NOT a law enforcement conversion. 1) Is there a difference between the LE6920 and the AR6920 uppers? 2) I've also seen collapsable stocks designated with the "M4 heavy buffer". Is there a difference in butt stocks currently available on the market? If so, why? Thanks!

There are actually 4 different buffers. Standard shorty buffer. These other buffers are usually only used in select fire guns: C buffer has a sliding section and is for use in the Colt Commando. H buffer is the heavy buffer, for use in the M4's. Hydraulic buffer has a piston section and can be used in place of all 3.
