I've just started playing with an at-10 upper build. 22" fluted stainless barrel in 243 caliber. Have tested the upper with barrel attached on my existing lower and BCG feeds and chambers fine. Still looking for a 0.936 adj. gas block for it. Anyone with experience building an upper to give me hints or pitfalls to avoid. 1 discovery I've made is with a heavy-assed barrel like this you can change the center of gravity by shortening the stock a click or 2 and really change the feel of the gun.
