AR6720CK-NHG

AR/M4 AR General Discussion

Got one of these in with a shaved front sight base and (understandably) no delta ring assembly from Guns Midwest this month.

Anyone else know that was an option?

EDIT: this is an AR6720CK-NHG (conversation kit, no handguard)

Also note, this is actually a very welcome surprise, though I did specifically want one with front sight. I had thought about purchasing a second specifically to shave the FSB and do this.

I did not. But I have been wishing for one. Can you post a pic? Where did you buy it? I can’t find any ’ 6729’ uppers, just the 6720.

Posted the link to imgur, seemed a little easier than trying to post the pictures. I also corrected this to be “6720.”

According from the ad from Guns Midwest and other I looked at, it should have a FSB and Delta ring. Here are a few of the ones I looked at.

I would actually prefer the one like the OP got with the shaved FSB. Interesting…

6

I certainly do…just want to make sure it is “legit.”

From what I saw at other sites, as Renegade shows even more thoroughly, the ads clearly have it with a FSB…

7

You could always contact the seller, and see if they provide you with any clues.

8

I would say it’s legit. Dam wish I saw these.

It ain’t no thang to shave an FSB

10

True, but to have one that looks good and that is phosphated after it’s been shaved is quite nice.

I think I would have a hard time not buying one of these if they became available again.

556cliff, where I purchased has more, as far as I know. Thanks for the link to G&R, I should have checked there. I received what is in their picture. Not a knock on G&R, I’ve spent money there before; however, I paid $503 shipped. Despite the inaccurate description, I received something I really wanted and am happy.

Did the upper from Guns Midwest include a BCG and CH? It’s not mentioned in the description.

Thanks for the heads up.

Colt shaved the FSB on these incorrectly. They left the “web” of material between the gas tube journal and the barrel journal.

15

Do you mean it’s not “rounded” enough (best way I can think of to say it). Like the top on the front and rear could be rounded more and less flat?

16

Included was the assembled upper receiver, bolt carrier group, and charging handle.

17

Is this what you’re talking about? Kinda like they did the job halfway?

I’m gonna guess that is what he was referring to. I have a Colt 6920 OEM-2 and the shaving looks MUCH better than that pic, much more “rounded” and slim-line.

19

I would LOVE to have a 6960 CCU upper in that configuration, i.e. no handguard. I never expected this configuration so maybe they will do it for the CCU also one of these days.

Thanks; that is a screaming deal.
