I have a 20" J&T Wilson Bullbarrel. It is an A3 flattop with freefloat hand guards. With handloaded ammo and a good quality scope I have gotten 5 shot 1/2" MOA groups at 100 yards with this upper. I can easily get consistently less than 1" MOA with just about any type of quality off the shelf ammo.
It looks just like this upper except it has the standard A3 flattop with forward assist and ejection port cover not the highrise style shown.
I am currently looking to sell it since I am funding a new project. I have less than 500 rounds thru it and the barrel was painstakingly broken in. I would be willing to sell it complete with bolt carrier and bolt assembly for $400 or best offer(less scope of course).
Let me know if you are interested. E-mail is
