I wussed out on the starfish. Lol. I only have two so I’ll have a 19.5” 223AI and 20.5” -21” 6 creedmoor. I’m a little curious about barrel lengths anyway. 300 win will be 21”. 280AI 19” 18” 6creed and 17” 223 17-18” 243. Curious about balance too. Will see what’s what with these and go from there.
