What manufacture makes the most accurate upper ? 18" or 20" lenght. Many of them say sub-moa at 100yds but what about 300,400,500 yds ? Let me know what you think. Thanks

The common saying in the car world is "Speed costs money, how fast do you want to go?" In the firearms world, it's "Accuracy costs money, how small do you want your groups to be?" Honestly, you could spend $500+ on a Krieger barrel alone, which is more than most complete uppers cost. Have it assembled by a top notch custom gun smith and you might be looking at $2000+ for a complete upper assembly. The limiting factor for range though isn't your barrel, it's the .223/5.56 caliber. If you want long distances, then something like the 6.5 Grendel is probably the way to go.

I'm talking fully assembled froma manufacture. Colt, Bushmaster, DPMS, Olympic Arms, Armalite, etc. Not a custum build.

Armalite offers a 20 and a 24" upper with a float tube, Wilde chamber and a eight twist. Each rifle is its own..... but this is a good combo for a factory set up. What ever you buy, you will not know how well it will shoot until you pull the trigger, so to speak.

Also, semi custom uppers are available for not much more. This way you begin to have a little more control of the quality and expertise in the product. If you are interested in shooting beyond 300, This is an option to more closely consider.

eta; I just remembered seeing a particularly nice and proven Knights upper, SR-15 match, mabie, Excalibur Arms, near Daytona I think. That may be worth a call.

Try Fulton Armory's Predator Upper with the 26" Krieger barrel. 1/2 MOA guarenteed. $1050 and quite possibly the longest barrel you can buy off the shelf for an AR. It doesn't get any better than that.

You can get them in 20" too but the range you're talking about will be harder to achieve. Sorry, but in this case it's an either-or type of deal. Longer barrel = more time for the bullet to accelerate = longer range. Like I said before, if you want those sorts of ranges with a 20" barrel, 5.56 is not the way to go.
