204 20 inch upper
Delivered to me very fast and packed well. The FDE cerakote that I got was beautiful. This is by far the best shooting upper in my arsenal for accuracy. I loves 35 gr vmax. Groups were almost touching and that's probably my fault. Bring on the prairie dogs.

204 Upper Assembly
Planning a prairie dog hunt in the spring and this is what I'm taking with me. Furthest shot I'm told is 300 yards so with some good glass, this is plenty. Already getting 1" groups with some hornady 35 gr vmax factory so should improve with my hand loads.

Shipped quick.
Got it out to me next day, so thats impressive. Very satisfied with grouping at 100. Got right at 1" MOA with some cheap factory loads but I'm sure with match or handloads it will be 1/2" or so.
