I am new to long range shooting but not new to firearms. I am doing a AR10 6.5 Creed build. Mostly Aero. I am looking for tips from people who have built AR10's. I don't so much want advice on products, unless it's general, like "you will get the most improvement for the money from a trigger/barrel/scope..." I am really looking for advice on info like does lapping the upper really help? What small things do people overlook?

I am not trying to get the most accurate rifle on the range, but more to find that sweet spot of the most accuracy for the least price.

FYI I have chosen the AR platform simply because I love to build things. Please don't tell me to go with a bolt gun. I am doing a separate build of a Tikka T3x. This AR build is simply for fun to see how accurate an AR I can build without breaking the bank.

Thank you for your input!

Lapping shouldn't be necessary for a quality receiver, but if you have a lapping tool on hand, it is a good way to check that it is square. Once the finish on the face of the receiver is fully removed, you don't need to go any further with lapping. Disclaimer* I'm merely speaking as an AR15 guy, but the same mechanics are simply working on a larger scale. I would definitely not skimp on a quality match grade barrel from a well known maker as it's one place you can usually buy some accuracy potential. Guns are just barrels, everything else in a modern rifle is there to hold, aim, fire, and reload the barrel as consistently as possible (this is where the other accuracy tricks usually come in). I would read and watch as much as you can find on this site about AR10s. They are not standardized as much as AR15s are, so you can run into more compatibility issues when building a rifle. As to accuracy, those guns are harder to shoot to their potential unless your marksmanship is on point (harder to separate the gun or ammo problems from shooter problems) Most guys seem to hover around 1 MOA accuracy.
 
You can increase your odds of a good shooting AR by doing a lot of those simple DIY things.

Gas port tuning = Adj GB .... and I polish the inlet on the gas key.. just smooth it up on the conical surface...

Also make sure the gas block doesn't sit flush against the barrels shoulder.

I could go on and on... when it comes to the tiny details.

And.... I FIRMLY believe in the merits to a snug fit between the upper and lower. Loose fit makes it harder for you to wield the firearm consistently.

As far as components go, for the buffer system I’d consider the JP silent captured spring/buffer. I upgraded mine to this and it makes for a much more enjoyable shooting experience especially if you plan to run suppressed. Won’t make the gun any more accurate but it will make it a joy to shoot. Of course I’d recommend an adjustable gas block to pair with it.
 
Adjustable gas block, quality trigger, quality barrel, and a stock that fits you and is comfortable. I do recommend a keyed handguard to make sure it stays properly aligned. The newer reinforced handguard like what Seekins and a few other companies make are nice. They provide more material where the handguard mates to the receiver providing a stronger link up with less flexing.
