I miss the 20" barrel for various reasons:
1. They are cool
2. I like them
3. I believe they are a little more reliable than the carbines. Also, more accurate and offer improved performance...maybe not that much but somewhat better in any case.
4. Everybody and their sister have carbines and I would like something different.
5. I am not a tactical guy, nor do I play one on TV.
6. I do not like middies
7. I want something I can keep light and simple (yes the 6520 is light and simple too...and very sweet)
8. I do not clear buildings or rooms for a living, nor do I expect to have to do this any time soon....so compactness does not really make much of a difference to me
9. Full size rifles feel better to me
10. I can use a bayonet on a 20" barrel and not that much with a 16" barrel unless I haveone of those middies which I do not like to begin with.
With that said, I will concede that there are some advantages to the carbine just not for what I need it. Regardless I will probbaly end up with a carbine as well at some point

Well I like 16" and 20" myself.. My next rifle will be a 20" but I do like my 16" its an Armalite Middy.. I find it to be the best gas system, its very smooth.. I will prolly get a Armalite 20" and put a the EOTech 557.4X MPO Multi Purpose Optic Holographic System.. I like fast short to long range shooting so this will be very good for that or I might put Another TA31F like I have on my Armalite Middy 16"HBAR.. I find the ACOG to the the fastest Optic for all around use.. But I know I will be getting a 20" as my next if not a 16" I never shoot past 600 yards so a 16" is good for me but still I know a 20" will help some at any range..
I think the M4 Carbine setup was developed in response to different combat/application situations. Much easier to manuver with a carbine and collapsed stock in a squad car, then a full size. The shooting patterns are also changing. Many departments really stress "cutting the pie" when taking corners, and those extra inches out front make a convenient hand hold for someone to grab the firearm. The M4 is also easier to use in tanks, and when going in with parachutes. Yes you sacrifice a bit of accuracy; for nearly all urban settings now, the planned range is within 150 yards. In that distance, the accurracy difference isn't significant enough to matter. You will still find a couple of the platforms in the departments with the 20" barrels, for those situations demanding higher accurracy at longer distances.
i'm compromising and going with the 16" barrel and adjustable stock.

Barrel length doesn't have anything to do with accuracy, that's a fallacy. To steal a quote from someone. "Intrinsic accuracy is a matter of quality, not length."
In the AR platform barrel length affects sight radius, velocity and thus effective range.
I would like to see someone offer a nice 20in 1/7 twist milspec barrel with an A2 upper. I'd like to replace my old Colt AR-15A2 I sold off in the mid 90's for some unknown reason.

Well it can in alot of many ways.. Even as simple as somthing like having a 4" barrel on a pistol then moving to a 7" barrel.. you will notice a difference in ease of aiming.. Accurcacy is not all about the gun it is about the shooter to.. It affects the range most but there are other things it will affect to.. I use a 16" non match HBAR and I get under 1" groups at 100 yards with my Armalite Middy.. That is on my good days and when I am using good ammo.. I pull off 1" group's 80% of the time with UltraMax 62gr or Prvi 62gr FMJ but I found that Prvi 75gr BTHP Match ammo will give me my best groups along with 69gr BTHP Match.. But They rounds just cost to much so I stick with UltraMax 62gr most of the time.. 1"-1.5" groups are good enuff for me.. and I found out of all the barrel lenths I like a soild 16" the best.. Perfect for 600 yards with 62gr and if you put some good match ammo in it you can get it out to 800+ with ease.. 14.5" Barrels are nice if you are going to be doing alot of close range stuff and never need to pass 600yds.. and a 20" would be good for doing alot of shooting past 400 yards.. a 24 is best for 800-1200 yds.. But the avg shooter will pretty much be around 25 yards to 600 yards with an AR.. so I find the best for the avg shooter is a 16".. and it can be about luck I never would have thot my Armalite would shoot sub moa with match ammo and it being a 1/9 twist.. some people will say you need a 1/8 for 73gr+ but I shoot 75gr best with my 1/9.. It is pretty much due to the fact some 1/9 barrels are closer to 1/8 and some are closer to 1/10.. if you buy a "good" rifle you have a better chance of getting a 1/9 that will shoot heavy rounds but it still is not about that... it is pretty much just luck.. Unless you buy a match rifle/Barrel then you dont know if you will get sub moa.. but it will be around 1" for sure not any higher then 1.5" in most cases..
