I am fairly new to the AR world, have a 223, decided to get a 204 Ruger as I really like that round, buddy suggested the WOA. So, I got the 24" varmint edition, put it on last weekend, 1st 50 rounds and have 2 groups that are 1 hole, 1 is litterally 1 hole and 2nd are stacked on top of each other vertically. Also tried out the Brass Goat brass catcher, worked perfectly. Shot the groups at 100 yrds, indoors, 32gr vmax, 3950 fps. I am going to have some fun in the P dog towns this summer!
