Haven't received it yet but now wondering if I should cancel and get a BCM upper. Thoughts?
**Update** Shipped it back. Read on for why **Update2*** Just got off the phone with Colt. He said there were a number of uppers that were accidently missing the BCG and CH. I admit I was really fuming so I shipped back on reaction, but I plan to get a LMT or BCM. So giving ya guys a heads up not to freak out like I did.

Just built a complete Colt Upper with Colt 14.5" SOCOM Barrel Which is what I've got and I'm quite happy with it. http://www.ar15.com/media/viewFile.html?i=68430 An excellent choice in barrels. I performed an accuracy (technically precision) evaluation of the Colt SOCOM barrel following my usual protocols. All shooting was conducted from a concrete bench-rest from a distance of 100 yards (confirmed with a laser rangefinder.) For the accuracy evaluation, the barrel was free-floated using a Daniel Defense Omega rail. 
This accuracy evaluation used statistically significant shot-group sizes and every single shot in a fired group was included in the measurements. There was absolutely no use of any Group Reduction Techniques (e.g. fliers, target movement, Butterfly Shots). As many of the significant variables as was practicable were controlled for. The free-float handguard of the carbine rested in a Sinclair Windage Benchrest, while the stock of the carbine rested in a Protektor bunny-ear rear bag. Sighting was accomplished via a Leupold VARI-X III set at 25X magnification and adjusted to be parallax-free at 100 yards. Wind conditions on the shooting range were continuously monitored using a Wind Probe. The set-up was very similar to that pictured below. 
The Wind Probe. 
Using match-grade hand-loads topped with Sierra 55 grain BlitzKings, I fired three 10-shot groups from the Colt SOCOM barrel in a slow, steady manner from 100 yards. Those groups had extreme spreads of: 0.90” 1.02” 0.93” for a 10-shot group average extreme spread of 0.95”. All three of the 10-shot groups were over-layed on each other using RSI Shooting Lab to form a 30-shot composite group. The mean radius for the composite group was 0.35”. The smallest 10-shot group.

Colt is just as good as BCM. No issued BCM uppers out there. What did I miss regarding that being what measures the overall quality of a product? nothing. Assumption being a 6921 was purchased for clone purposes. quality was not being discussed, personally I would rather have a non-union upper myself. |

I think you'll be fine with the 6921. I'd personally choose it over a BCM upper of similar specs, including one with a mid gas system(the difference is argued a lot around here, but it's insignificant)
I've owned plenty of uppers and never regretted buying and keeping my 6921 upper, it will do everything you want a 14.5/16" non-precision upper to do, it also has the "Colt M4"name, which carries a lot of weight if/when you ever decide to sell it. |

I've sold off an Afghan upper, Infidel upper, 12" MRP piston upper, 10.4" 416 upper, CQBSS, Short Dot, TA31F, NF 2.5-10x24 and that's just the "finer things" At least I still have my BkII Noveske 14.5" N4 upper, LMT 10.5 "mk18" and my 6921. PVS 14, M4-2000, 2 Colt 1911s, 2 G19s, P226. |

The 6921 was from when I used to live in CA, so it's already pinned. and I have a lower registered there, so I can have evil features and I still have plenty of pre-ban 30 rounds mags still there. I'll pin the AAC 51T on my Bk II upper as well. NFA stuff wil have to reside at a "trustees"(brother) house until I'm free again. |

I'm always amazed at the love and view of quality that BCM gets here. BCM was made to be 'colt like' and is nothing more than a 'more aesthetically pleasing' Colt. I'd choose colt over bcm everyday of the week and I say with a brand new bcm upper and 2 bcm barreled rifles in the stable.
I do own a 6921 standard profile and a socom version as well as for the gas system....makes zero difference |

| Regardless of the brand you bought dont listen to the bickering here about what brand is better. Everyone has their oppinions and youre not going to change that. Around here bashing brands is like talking politics and religion with normal people. Shoot your rifle, enjoy it and learn it. When/ if ever you have to pull the trigger on something 2 legged or 4 legged. You will be glad you took the time to learn/shoot/inspect your stuff! |
| Well it has shipped already, I would have to ship it back to return it. I guess I had cold feet as in regard I could not find anything online about others who got one (most recent production), plus I plan to add a Centurion C4 rail besides pinning a pws traid, going to be sending it to Rainier for that. So the fact I wouldn't shoot it till it was done made me flinch. I know colt is good but I have heard of occasional issues and of course BCM is gold right now. So can I get more reasons to keep it or not? Also seems like everyone is going middy though. |

| Got to FedEx before it closed, so it's on its way. Really just blown away, I half wonder if a FedEx employee got in it because that piece of cardboard or what ever that is supposed to be in the barrel was gone as well. Colt will probably charge me a 20% restock fee and hopefully not charge me because they think I have. |

I like my 6921, I got the upper from he who cannot be named with the BCG/CH for $575 last year. Put the furniture/optics from my duty weapon in Iraq on it and cloned the gun from my avatar. http://i800.photobucket.com/albums/yy285/docrock184/Mobile%20Uploads/image_zpshegjsszr.jpg What laser is that on your rifle? |
OP, your choice is great don't over think it! Colt is top of the line and it will serve you well. I had three ARs and traded one to fund a BCM build just because I wanted a BCM. Get what you want but don't worry about what you already bought. Just wait you will build more, this is ARFcom just get both

Thinking a middy might be better for what I want. Depends on what you want to spend. Quality wise, they're on par. BCM wasn't just made to match Colt in terms of specs, but they're also a lot more open to new features and configurations. BCM is going to offer much more modern configurations (i.e., midlength), but you may have to pay more for it. The Colts are lower in price now than they've ever been - under 900 for a complete rifle. If you don't need a middy, or don't want one enough to pay extra (assuming it costs more), then just stick with the Colt. Both make fantastic rifles. Most people can tell a difference between shooting the carbine and midlength gas systems, with all other components being equal. Some people don't care about the difference. What tipped me over towards the middy was shooting with a can. |

Thinking a LMT 14.5 right now. I will get back to guys in couple days when I hear from Colt. You are all over the place. Just keep the Colt because chances are you'll never notice an appreciable difference between Colt, BCM, or LMT along with mid or carbine length gas. All of them are fine choices and none of them will let you down. |
