May be a bit late to jump in here, but +1 on what bkt said.
Colt makes a good product, and they have been around a long time doing it. They have had their ups and downs with quality, just like every other manufacturer out there. Having said that, they will be there in ten years if you want to resell the weapon. Colt has a name that people know, they also know that and charge accordingly.
There is nothing wrong with the right Colt. But, and I have said this a hundred times, for the MOST part, a receiver is a receiver is a receiver. There is a difference if you are buying a pot metal, pressed one out of junk, but I am talking the average, good old US of A made AR Receivers.
Unless you are buying a specific receiver that is either 1) CNC machine cut for a specific purpose, or 2) You are a brand name bigot and can't see beyond that fact, you aren't going to get some magical performance out of Brand X that you aren't going to be able to get out of Brand Y if the internals are all the same.
I don't have too many facts on the rifle you are looking at, so please allow me to think out loud on a few things.
Colt makes two types of receivers, ones with large pins ( around .172" or so depending on who is doing the measurement ) and ones with small pins ( around .154").
If you buy a model with large pins, and you wish to change the trigger group, you will have to buy a Colt compatiable model, which usually runs $10 to $20 more. Most models of "drops ins" will say something to the effect of "fits most model ARs ( except Colt ).
$1190 is a LOT of money in the AR world, even with the election looming.
If you are getting a free floated front handguard, with fold down analog sights, a good trigger and a good quality barrel, I can maybe see going that high.
However, if you want to throw $1200 at a 16" chrome lined, generic front end, fixed sight, A3 platform that goes bang, PLEASE PM ME
- I could use the ( at least ) $350 profit from making this for you.
EDIT: I JUST REALIZED YOU MAY HAVE POSTED IMAGES OF THE RIFLE IN QUESTION. I AM AT WORK AND THE NAZI I.T. DEPARTMENT FILTERS ALL HOSTED IMAGES. IF THAT IS THE CASE, I APOLOGIZE FOR THE OBVIOUS QUESTION ABOUT IT'S CONFIGURATION.
