Ok, we are dealing with two different parts here.
1. The upper: You say, flat top with m4 above gas port. 2. Barrel: You say, 16inch HBAR. What does the barrel have marked on it, toward the muzzle? Remeber a M4 means 14.5 inch barrel with m203 stepdown. What I mean is, barrel orginal to upper? |

Thanks for the quick response. The upper, towards the muzzle says "5.56 NATO HBAR 1/9"-- or something similiar to that, its been at the gunshop for a couple weeks. Now the book did say that colt made a limited number of these uppers with this barrel. I of course do not know hardly anything about AR's even less about Colt's. If this is really 2 different parts then it will not hurt me too bad to get it cut on, plus the bayonet lug is so far back, only about an inch of blade comes past the suppressor.

Reptilex,
i am a Colt AR-15 collector, what i think you have there is a bastardized "A3 Tactical", as there is no "M4" stamped in the upper on a true 6721 upper the only Colt AR-15 that i know of that demands a price above $4,000 is the "Colt AR-15 A3 Tactical".., YES...!!! there were 134 of them made & i have one, if the lower receiver does not have that specific designation it is NOT an original "Tactical" also the "Tactical" has a S/N starting with BD000XXX & the barrel is 16", has no "step" & is a heavy weight if that "Tactical" has a S/N above BD000134 it is considered a LEO/Military only weapon, cutting off the bayo lug & changing the FH will render the gun "JUNK", & will NOT make it legal under any circumstances, it is the S/N that determines whether a rifle is or is not pre-ban... can you post a photo ? if not, give a full & complete description of this gun..., i mean every single stamped lettering, both upper & lower..., my best guess is that someone is trying to sell you somthing priced about $3,000 too high !!!!!!!!!!! |

Quoted: as there is no "M4" stamped in the upper on a true 6721 upper Err... Both of my 6721's, serials < BD000100 and received by me NIB, have the M4 marking above the cloverleaf. |

I cannot post a pic because the upper is at the shop right now. I will describe it best as I can from memory. It is a flat top receiver. It does have "M4" stamped on it behind the handguards. There is no serial number anywhere on it. It has C AF stamped on the side and I believe it has an "F" stamped on the front sight post. It has the "5.56 NATO HBAR 1/9" stamped on top of the barrel. I cannot swear that the barrel is chrome lined. It doesnt have LEO or military use on it anywhere and I do not have the lower. I was wondering what lower I would need to make it original even though the price of preban colt lowers is astronomical. Thanks again....

The gun will have C on the [b]barrel[/b] if it is a colt. Look at this pic [url]http://www.biggerhammer.net/ar15/barrelsbolts/[/url], to see what I mean. Lots of people get a M4 flat top upper, and put a 16inch barrel on it to make it a legal length upper assembly. There are no serial numbers on the upper receiver, or barrel. Only the lower receiver has the serial number. Just call the shop and ask what the barrel has stamped on it, and let us know. |

Sorry I am confused here...do you have the whole gun including the lower or just an upper? I could be wrong here but there would be nothing on the upper to indicate that it came off one of the Rare BD guns except the matching lower. If all you have is an upper in 6721 configuration then all you have is a Colt heavy barrel upper??? Nothing special. A 6721 upper could easily be duplicated from parts, with out the lower there is no collector value in my opinion.

Quoted: Sorry I am confused here...do you have the whole gun including the lower or just an upper? He has the upper only. It is most likely one of uppers sold by Colt as a "conversion kit" in the late 90's. In exc. condition with the b/c/ch included, the value is about $600. |

First off, thanks for all the feedback, it has been helpfull. The barrel does have " C MP 5.56 NATO HBAR" stamped on it. Also I found out that cutting the bayo lug off will not harm the value if I just get a new front sight assembly from Colt and put the suppressor back on it. I believe there is probably no way to tell if this came off one of those weapons. I just wanted to find out before I mutilated a rare find. Thanks again, everyone.

I agree with the guess that you most likely have the upper from an R6721DC conversion kit.
However the prices I've seen for those are around $800/$900 if bolt and carrier are included. (NIB prices) If it were mine I don't think I'd be doing any cutting on it. I'd at least hang on to it until next Sept. and see what happens with the AWB. |

I just checked out the Colt R6721DC and it looks excactly like what I have. How can I tell if I have the conversion upper or one of the real deals ? There are no numbers that I can recall. Can anyone tell me if there are numbers and where they would be located ? If this conversion kit has the M4 stamped on the reciever it most likely is what I have. I am a pessimist by nature and while I know the awb will sunset I figure they will have a newer bill that will take effect as soon as it does. nO sense in getting my hopes up. I am going to cut off the flug and change the FH so I can take it to the range and fire it with no worries. I don't have the money to buy another upper and I definately don't have the money to buy a preban lower (those prices are insanely overpriced). Thanks again !

I am not familiar with the 6721 as a complete rifle and don't know if there is any definitive way to tell whether the upper was from a 6721 conversion kit or from a factory assembled 6721 complete rifle. I suspect there isn't but perhaps someone more knowledgable can provide one.
I can't tell you from memory what the markings and inscriptions are on an R6721DC conversion kit upper are but I'll try to remember to check and post after I get home this evening; probably around 7:00pm PDT. |

_____________________________________________ Ok, has anyone that reads, frequents this site, ever been out shooting, and had [b]ANYONE[/b]come up to them and ask if... their gun was a pre/post lower with pre/post upper.

Reptilex72,
The markings on my R6721DC conversion kit upper are as follows: 1. Barrel marked on top: C MP 5.56 NATO 1/9 HBAR 2. On the right side of the receiver above the forward assist it has a "C" followed by a symbol which looks like it is formed by taking an "A" and an "F" and squeezing (highly technical term) them together; it sort of looks like "C AF". 3. On the left side of the receiver towards the front about 1/2" below the rail it has a symbol which looks like a "C" rotated 90 degrees to the left and surrounded by a square or a rectangle. 4. On the front of the receiver above the gas tube it is indeed marked "M4". 5. On the front site base it has an "F" on the left side and on the right side it has an "A" followed by a symbol which appears to be a circle containing the letters "RI" (or maybe its "R1") and then followed by a "1". 6. I didn't notice anything else but its been a long day.... Hope that helps. |

there is NO difference in a kit 6721 & a 6721 on a complete factory made rifle......
as for destroying a $900 upper by hacking on it....., i am with Spooge on this one..., leave it alone !!!!! or sell/trade it to me & i'll get you a "LEGAL" upper...., very cheap !!!!! |

Reptilex72,
Another way to play this... Is your upper NIB or LNIB? If so that 6721 upper is a reasonably valuable commodity in its own right. Given the price an un-hacked on 6721 upper might command you may be able to sell it for around the price of a brand new post-ban. I haven't priced any lately but I'd bet you could get a pretty decent brand new post-ban Bushmaster for around $800 or thereabouts.... I don't think you'd have too much trouble selling it on the EE here.... just some early morning rambling.... |

This is a lot of food for thought. I would have considered selling this upper and gotten one of those with the 203 stepdown except for the fact that this one I have is kinda rough. Some of the finish is completely worn away in places and the FH is scraped from where it looks like someone tried to twist it on too tight. So if nothing else, I am just going to have it refinished. I had no idea that these AR's were so complicated AND expensive. Heck, I have 500 bucks in just this upper and the colt bolt/carrier. Not to mention the flip up sight that was a hundred bucks. I hope I don't get addicted to these things.
So... If I have this upper "legalized" it will be worthless ? Even with a new Colt front sight assembly and a new A2 suppressor ? The finish is a given,, that would have to be redone anyhow as it looks like crap now. |

Well I think "worthless" is way to strong a statement.
It's just that if you take a firearm or in this case a significant subassemby thereof and modify it you usually find that you have taken away some of its inherent value even if there is no functional degradation. That may or may not be important to you. It doesn't have to be; it's a personal thing; maybe what is more important to you is that it is put into a configuration that makes it useable; in this case making it legal to use with a post-ban lower. Everybody has their own priorities and needs. We are probably over analyzing this and making a bigger deal out of it than it deserves. |
