Yes the 6720 is the pencil barrel but you won't notice any accuracy differences in a carbine IMO and the heavy barrel is why the 6721 is too heavy to you. I've put older smaller diameter 6 hole Colt handguards on the 6720's that I've owned. Makes it into a more modern 6520 in essence since it has a flat top and thus lighter depending on mount/optic used. Other than a SBR Colt has never made a lighter 5.56mm AR15. Earl

I would like to see a dissipator model with a midlength system...that would be sweet...don't forget the flat top for those who want to use optics.

The 6720 has the thin profile, doesn't it? I thought it wasn't super accurate? Also, the 6720 has a 1/7 barrel and will handle heavier loads. The 6721 and its 1/9 cannot. You won't regret the 6720 and it sounds exactly like what you're looking for. |

If we are putting Christmas wishes out there, I would like a MK18 OEM variant.......factory 10.3" barreled upper receiver mated with a M4A1 CARBINE lower receiver, complete with 5.56mm roll mark, low profile gas block, no furniture, etc. But my guess is we will probably just get another 6920 with the latest Magpul furniture marketed as a completely new and redesigned model for 2018.

I'm curios now as to the accuracy difference between the 6721 barrel and the 6920 barrel. From looking online, it does not seem to be that big of a difference.

Depends on the individual guns and the bullets you are using. The 6721 is a 1/9 twist, the 6920 1/7. Generally speaking this means that the 6920 should be more accurate than the 6721 when using heavier bullets - especially anything above 62gr. That said, some 1/9 twist barrels do handle the heavier bullets ok so that's what I mean by it can vary depending upon the gun. I currently own and have owned many 6920 carbines. I've also owned 6520 and 6720 carbines - I love them. Personally, I have never owned a 6721 and never will because I have no use for a 1/9" Colt barrel - none.

I know, but I'm looking for uppers like Colt Canada Mlok, or even the slick side non picatanny rail version |

So maybe a barrel with the mass of the 6920 govt profile barrel, but with a different profile? Better heat dissipation under the hand-guards and maybe without the m203 cutouts (which might negatively effect accuracy)?

I would like an LE694x upper that has the 901's awesome threaded modular handguards. Maybe make it a mid-length heavy barrel to boot and it can be an "official" 901 5.56 companion upper.
