I called Kyle to ask him a few questions he was very helpful and he agree to upgrade the bolt carrier for the price difference between the two. Shipping was fast. When I got the upper it was in good condition
It fit perfectly on my Anderson upper. I do not have good sites for it yet but it functions flawlessly.
Except it does not like steel casing ammo. If you are thinking of getting this upper remember the fluted bull barrel it was heavy it makes the rifle weigh about as much as a SKS rifle. If you're okay with the weight it is a great upper. If you found this website you been looking very hard for the best deal and I believe this is it. But don't wait long Kyle said this deal will not last!..

My first AR build. This barrel is very finely finished and looks awesome. I paired the BC upper with an Palmetto lower loaded with Magpul furniture. All I can saw is "WOW!". I'm totally blown away at the accuracy. I'm no marksman, but he very first round down range was low and to the left by 4 inches and I was drilling every round through a baseball-sized pattern; standing up, using a cheapie red-dot at 75 yds! I'm completely sold and in love with my AR. I can't wait until I get some real optics on it. It's a fine weapon at a finer price. The BC barrel is the key element. Grab one, you won't be disappointed...
