Op, it looks like a cool rifle.
Ceracoat turned out really nicely. Hopefully you enjoy it and get tons of use out of it.
Please don't take my comments too hard, or even as a critique of your build, I'm just trying to share some of what I've learned about building ARs over the years. In the end, it's your gun doing what you need it to do, just don't get too hung up on the approval of the people on this board. Your gun should reflect your needs and wants and not the opinion of others.
Don't get too hung up on the "should have bought a factory gun comments." While it's true there may be some better values out there in factory guns, I firmly believe that building your first AR is a rite of passage into serious gun ownership. It also teaches you important lessons about the actual function of the weapon and the relationship parts all have with each other. You can also diagnose and troubleshoot more easily knowing your gun in and out. I have also had just as many reliability issues with factory guns as builds.
In the future, as I'm sure you can tell from the comments, focus on the barrel and trigger. Those will make the biggest difference to your rifle. Nothing wrong with Faxon either, great barrels. This is just where I would have put more of my budget.
An adjustable gas block and a sturdy BCG are next on my list. I've used just about every brand of BCG out there, from basic PSA to eye-wateringly expensive top teir brands. Unless it's a purpose built competition rifle or I'm chasing a weight number, I now stick with Toolcraft milspec ones. They have been every bit as accurate as my JP, Young, etc ones. And usually more durable. Daniel Defense, Colt, and a few others have been just as good, but are more costly.
Finally I look for a handguard/barrel nut combo with as little flex as possible. I have found Geissele to be the best, but there are plenty out there that work great. In a true precision build, I'm also not running an extremely long 15" rail, as that extra length can put more torque on the barrel/nut/receiver and affect accuracy. Otherwise
In the long run, you're not likely to notice much of a difference in performance with your receivers across the budget spectrum as long as they are properly in spec. Looks, etc. are another story and completely subjective.
I've also spent a lot of time looking to improve my reload times and increase performance/decrease times with a huge range of lower parts. An ambi safety and good trigger, and MAYBE a larger mag release are all I have found to make a difference. I stick with cheapo LPKs now sold without a trigger and drop in a Geissele.
Finally, I think the majority of the negative reactions you got in this thread we're due to your thread title. I don't think you meant it as such, but it came across as a bit braggadocious. That can rub people the wrong way here, whether it's because they can't afford a build like that, or they know that putting 3k into a build is no guarantee of performance. Or they just don't like people flaunting their money. Frankly a lot of the replies here were more fitting for General Discussion and not a tech forum, but OP, you did kind of walk into it with that thread title. Again, I think your heart was in the right place, but it's hard to get a read on someone in a thread.
Remember, this website contains some of the meanest, snarkiest, most malcontent sons of bitches you'll find anywhere (kind of reminds me of the line of villains in Blazing Saddles) but you also will never find a group of more knowledgeable and helpful folks in regards to the AR rifle and guns in general.
If you have any questions about future builds, feel free to IM me. I'm far from the most knowledgeable person here, but I will always try and give you straight answers on AR15 stuff, and let you know if I don't really know. Enjoy your build and welcome to the hobby.
