What do you all think of the 6721 ? mt understanding is that the only differance is the 1/9 twist and barrel profile . Seems that alot of departments are using th 6721

It's a good gun. I have an LE version I got during the ban years. The only thing that I wish was different is the ramped/half circle carrier.
Colt didn't always put M16 carriers in even the LE guns.
They are very heavy for a carbine, and 1/9 isn't for shooting 70GR and up rounds....but other than that they are a good gun of typical Colt quality.
New ones should come with the fat M4 handguards, M4 stock, M16 BCG, standard size trigger pins, carry handle, etc.
Basically just a 6920 with a different roll mark and barrel.
I have one,
its a good gun and the weight helps keeping the carbine tacticool-crap-free
I prefer 1/7 as all around twist ratio but 1/9 works great too...not a huge difference

they are gtg...i carried one in my trunk for several years. if you see one at a decent price grab it, otherwise just get a 6920.

1/9 twist and a heavy barrel. If those aren't an issue for you, it's a great choice with typical Colt quality and reliability.

I thought they were just a 6920 with a factory 14.5'' barrel.
Damn. I was wrong. Glad I didn't advise anybody to buy one.

We miss you, AC.
We miss you, ToddG.
Yeah. That's the 6921 I believe.
I probably wouldn't buy a 6920 or 6721 today. If I'm going to have a carbine gas system, I'm not going to suffer with a full 16" of barrel too.
If yours has the hardened steel block in the lower preventing the use of a M16 carrier and want it removed check out www.HatfieldsGunsmithing.com. I've seen two they did and they do an excellent job of the removal of it. Then you could add whatever trigger you want into the lower as well as use a genuine Colt M16 carrier.
