is it just the barrel profile?

6920 is a 1:7 barrel w/ M4 profile.

the 6721 is a 1:9.

1:7 and 1:9...is that a big difference?

You need to read this:

Great info there.

thanks for the link

one more question, do one of the two seem to be more desirable? I might have a chance to pick up a NIB 6721 for like $920, but it seems like the 6920 is the one everyone wants.

if you can get the LE6920 for say a reasonable price $1000-1300 I'd say, TAKE IT.

Sell it for like $2000-2500 and use that money to get yourself a 6721 or a BMI pimpstick.

I don't know much about the 6721.

BOTH SHOULD BE BANNED FROM CIVILIAN USE!

well, I think for the $920, my choice is pretty much the 6721. or I can hold out for a deal on the 6920s.

6920 has the M4 barrel (1/7 twist) with the M203 cutout and M4 handguards, the 6721 is a full heavy barrel with no M203 cut (1/9 twist) and carbine handguards. Outside of that and the rollmarks I don't think there's much difference. I tell ya, I'm tempted to go for one of the 14.5" barrelled 6920s and pay the $200 tax stamp for the SBR. More authentic to the orginial M4 than the 16" version. Also not really being gouged as bad pricewise from what I've seen either.

6920 - is great if you have a m203 grenade launcher and use it regularly. The barrel diameter steps up and down about as often as John Kerry flip-flops. The oversize fore grip is about as wide as the water jacket around a 1919, so if you are into that sort of thing, I guess that's a plus. I doubt you will ever shoot a semi fast enough to justify "dual heat sheilds".

6721 - full heavy barrel with 1/9 twist which is more practical for heavier bullets and precision accuracy.

But don't let my bias affect your decision.

I tend to agree. The 6920 frenzy is largely about cosmetics, not functionality. I do like'em, but I'm not going to pay a premium for a no-ban rifle just because Colt, for whatever reason, isn't making it easy for civilians to get'em. To me, the principle involved is far greater than the cosmetics....and I have plenty of AR's already. If they become available in the future without having to bleed from the anus as part of the price, I'd likely buy one. Plenty of other AR's that are close to identical to the 6920's minus the roll marks. Not hung up on labels either.

Actually, the slower twist is better for lighter bullets as they do not need as much "spin" to get them stable.

As for which one to buy, if you get a chance at the 6721 for that price, take it. If I where going to buy one today, it would be the 6721 for two reasons;

1. 6721 is cheaper

2. I already have a 6920. hadnt
I would say if you can get it for less that $950, do it. A quick check of several dealer sites shows they are selling for $1100 give or take a $100.

Whose would you buy in stead?
Link Posted: 10/27/2004 3:01:37 PM EST
Colt LE6920 = 5.95lb
Colt LE6721 = 7.0lb
Colt M16A4 = 7.5lb

You know .... blah blah blah, whine whine whine, whatever.

LE6920 is the shiz and everyone knows it. Those that have it, sleep with it. Those that don't have it, are just jealous.

Just kidding!
