Basically the M4 is a compact version of the M-16

it's writen by a russian so sometimes it's hard to understand what he means but pretty informative
There just different variants. Most of the Military trains and uses the M-16 A2, but the new rifle being uses in close combat is the A4. same rifle its just that the A4 is shorter and a little bit lighter. You can also modify it easier
What would make it easier to modify? They are the same basic gun, with different options. ALL AR's are the same basic design with "cosmetic" changes in stocks, bbls, handgaurds, sights, internal parts, ect. M4 is a COLT trademark for a CURRENT miliary contract spec rifle. AR versions are the SEMI auto version of the M series guns, ie. AR-15A2 would be the same an M-16A2 just one is semi auto and the other full auto (to include 3rd burst). Just as there are many versions of the AR-15 the are many versions of the M-16.
Here are a couple more good links for you to check out:

AGAIN ANOTHER STATEMENT THAT ONLY MAKES SENSE IF YOU HAVE NO IDEA WHAT YOU ARE TALKING ABOUT: "the only reason they are just as accurate is because of the optics they slap on there. a barrel that is 6" shorter isnt going to be near as accurate. Yes they are the same out to about 200m. Past that is when they start acting "like" not exact, like an AK. I wouldnt buy one way to short."
Accuracy of the FIREARM has nothing to do with optics. If you take a gun and put it in a gun vice and fire it and it shoots 1MOA adding a scope will NOT change the group size. This is true for the M4 as well. Another reason you statement makes no sense is that you can put optics on any of the AR/M series rifles. Colt made scopes for the M-16A1's over 30years ago so what is your point? You make is sound like optics are a new thing on M series rifles. I will agree that the numbers of optics being used are on a scale never before seen but this has nothing to do with the accuracy of the FIREARM.
I dont have a FACTUAL answer for the distance before accuracy degrades below Militay standards in each BBL length, so I wont try. I do have this to say though the M4 was not designed to be a long range target rifle, end of story. The M4 was designed to be lighter and more compact for the "normal" type of conflicts we are currently fighting. The length was to help with being able to use from vehicles. If you are planning on using the rifle for what it was designed for it is perfect. If you are trying to shoot Nationl Match 1000 yrd comp with it you are going to have problems. It is the same as trying to use a screwdriver for a pry bar. It may work ok, or for a while but that is not the intened use for it!
nards444,
What are you saying? I've shot both and believe me the M4 is dang near as accurate as the A1 if not the A2. The AK good group was 12" at 100m.
Like Nwcid said they are basically the same rifle. The tolerances of the M16/M4/Car15 are tight. AK's are not. I qualifed one year at full range with a Car15 and still shot 40/40. The M4 is right along the same lines, you just have a lot more sight options with the picatinny top on the M4 is all.
